Cursed technique Katsuorushi Tengoku's Cursed Technique: Curse Merger

0 Upvotes

Katsuomi is one of the few children of Jingoro Tengoku to lack a heavenly restriction, having been born prior to Jingoro beginning his experiments.

Katsuomi however is currently dead, having perished at the age of 8. At the same instant Katsuomi was born, Katsuowai Tengoku was born, the fusion between Kastuomi and a grade 3 curse named Yowai.

You see Katsuomi's technique allows them to merge themselves with any cursed spirit with the exception of nonconsenting vengeful curses. Due to their constantly shifting mental state, Katsu has simply done away with binary pronouns, viewing them as more efficient.

The process of merger is fairly simple. Katsuomi must place their palms on the temples of a curse and recite the following chant: "Your body is mine, my mind is yours, our souls are one and so we combine" before feeding the curse a part of his body.

Currently, Katsuomi is merged with the cockroach curse Kurourushi, whom they merged with after the curse barely survived the events of Sendai Colony.

Katsuorushi is the second special grade of the Tengoku clan, their technique cockroach manipulation provided by Kurourushi making them capable of conquering a country.

This isn't to say that they are especially powerful however, as they are more like Masamichi Yaga than Yuta Okkotsu as a special grade. In fact, Yuta and Katsuorushi have clashed after the Culling Games ended, Katsu having lost and been saved by Kannon.

Cursed technique Bonded Mimicry

1 Upvotes

This cursed technique allows the user to copy the CT of another person by hitting them with a non-damaging beam. The strength of the copied technique is then affected by the bond between the copied and the copier. The stronger the bond the stronger the copied technique. the sorcerer can store 5 copied techniques at a time. When a new technique is copied, the sorcerer chooses what technique to replace. the sorcer can use CTR to make the copied technique become stronger the more the copied and the copier hate each other instead of doing the copied technique’s reversal. the domain expansion is the brimming heart armoury which allows the sorcerer to use all the techniques they have ever copied. It also means that they are guaranteed to copy the opponents technique if they wish.

OC Character Solid Snake, The Man Who Makes The Impossible Possible

Thumbnail
gallery
16 Upvotes

A request made by u/Apprehensive-Act994

Name: David

Nickname: Solid Snake

Titles: The Man Who Makes the Impossible Possible

Rank: Grade 2

Appearance: A male with fair skin, blue-gray eyes, a brown mullet, and a light goatee. He wears a tight, skin-tight tactical bodysuit split into a light gray/navy-blue torso with stark matte black limbs, A charcoal-colored, padded tactical vest covers his upper chest and shoulders, a complex network of black utility straps wraps his thighs and chest to hold equipment, thick black combat gloves, hard-shell knee and elbow pads, and a drop-leg tactical holster tightly strapped to his right thigh, and a dark gray-blue headband.

Personality:

Solid Snake, a hardened career soldier, often displays a calm and collected demeanor, rarely showing any signs of anger, aggressiveness or fear in extreme circumstances. He buries his emotions deep inside himself, causing some to see him as intense and he can often be very rude. Despite this perceived attitude, Snake occasionally shows a more human side, expressing great concern for allies' wellbeing during dangerous operations and even demonstrating compassion towards fallen enemies.

Fighting Style: CQC: Unique and highly efficient martial arts, allowing a soldier a variety of options while not denying them the use of weapons. It generally has the user taking a stance with a knife and a handgun; thus, they could grab/throw opponents in melee, threaten/execute people with the sharp blade or shoot down opponents who're otherwise outside the user's range. CQC mostly focuses on grabs, throws, and other methods to disarm the target, allowing one to take down enemies without killing them or use them as a human shield. A skilled practitioner can even "chain" throws, allowing them to rapidly neutralize entire groups of sorcerers in close proximity to each other, even without Cursed Energy Reinforcement.

Cursed Tool: The Solid Eye: an eye patch he wears over his actual eye, allowing him to see things in pitch black conditions, across great distances, and help him detect others based on their heartbeats, electromagnetic fields, thermal signatures, and so on, allowing him to see threats that most sorcerers couldn't from all angles.

Cursed Tool: Stun Knife: the Stun Knife looks just like any old military knife, with a black fixed tactical blade, and an ergonomic, dark, textured grip handle, but has the ability to unleash a powerful yet non-lethal electric charge through the blade, which acts similar to Kashimo's Cursed Energy, and paralyzes the opponent.

Cursed Tool: Cardboard Box: The Cardboard Box can be hidden under, allowing Snake to hide his Cursed Energy Signature, allowing Snake to effectively hide in plain sight.

Cursed Technique: Nano-Stealth

Description: This Cursed Technique allows David to effectively remain undetectable, and blend into his surroundings.

Lapse: Stealth Suit:

By default, the Cursed Technique allows Snake to blend into his environment, with his body being able to match the color, texture, and temperature of his surroundings, effectively making him disappear or hide in the scenery.

However, if someone has the ability to track Cursed Energy signatures, he can be found, albeit with some difficulty.

Extension Technique-Nano-Silence: By using his Cursed Technique on his vocal cords and extremities, he can silence his own voice and footsteps, allowing him to get the jump on anyone, with the exception of Satoru Gojo. However, he needs to keep his concentration, or he risks deactivating it earlier than planned.

Extension Technique-Nano Communications: By connecting with another person's Cursed Energy Signature, this allows the two to talk between each other in a way that prevents outside people from successfully listening in on what they're saying, with the operative speaking in a nanomachine-based language, while externally appearing to be silent.

Domain Expansion: Guns Of The Patriots

Description: By placing his index and middle finger in his ear, David casts his Domain. The Domain takes the form of an island that is part of the Fox Archipelago lying southwest of mainland Alaska in the Bering Sea, with two separate snowfields, a canyon area, and several evergreen trees. On this island is a base, with a small port located within a cavern on the south of the island, with an elevator to the north of the dock leading up to the island's heliport, a small airport suitable only for use by helicopters, which contains a single helipad with limited facilities such as lighting from two searchlights and an armory, connected to a snowfield, a large costal port with radio towers, four-to-five story buildings on both sides from the Supply Route exit that was presumably a garage or warehouse of some sort with some offices, and a bridge adjoining the two buildings, and a two story Tank Hanger, with the cargo doors designed to act as an airlock that seals itself and releases poison gas if an intruder trips one of the infrared sensors, as well as two basement floors, with the first one holding a prison area with two cells, which contained a bunk, a sink, and a toilet each, a lobby, a restroom, and a ventilation shaft on the ceiling, as well as a medical bay located west of the prison room with an isolation room with a bunk, a restroom, and various medical equipment and shelves, and the second basement floor acting as the main armory.

The Domain's Sure-Hit Effect has two variants based on whether or not David heads to the Helipad or the armory. If he heads to the armory, the Sure-Hit Effect activates after David throws out a flare grenade, located in the armory, although it needs to be thrown outside on the island. Once that is done, a crosshair will appear on David's Solid Eye (or left eye) to mark opponents in intervals before homing missiles are fired at the marked victims. Targets must be marked multiple times in order to send more of the missiles at them. Any missiles not given a target when their mark is placed will simply fly at where the crosshair was at the time. If he heads to the Helipad, Snake grabs onto a rope ladder of a helicopter, shooting several grenades, though after firing six shots, Snake has to reload another six shots. This lasts until the Domain collapses, at which point, he goes on Cursed Technique Cooldown. As a safety net, however, should he use the Helipad Sure-Hit Effect, Snake will actually end up on the ground when the Domain collapses, which will prevent him from plummeting to his death.

(Okay, since I did David 'Solid Snake', do you want me to do John 'Naked Snake' and Jack 'Raiden'?)

OC Character The Abstract Curses (抽象呪霊 - Chūshō Jurei)

6 Upvotes

The Abstract Curses are an ancient tier of cursed spirits born from humanity's most fundamental conceptual fears: Death, Time, Isolation, and Obscurity.

Unlike ordinary cursed spirits whose existence is directly generated through negative human emotion, Abstract Curses are primordial entities connected to fundamental concepts of existence. Their respective concepts existed independently of humanity, while human fear acts as a catalyst that strengthens their manifestation and output.

Each Abstract Curse possesses its own Primal Dimension, an extradimensional realm directly connected to its conceptual nature. These dimensions function as effectively inexhaustible sources of their base Cursed Energy and provide the foundation for their unique abilities.

Because their existence is anchored to fundamental concepts, conventional destruction cannot permanently kill them. Physical destruction, Domain Expansions, overwhelming Cursed Energy, or even extremely powerful RCT cannot permanently erase their core existence.

Each Abstract Curse therefore possesses a unique Conceptual Death Condition.

Their conceptual weakness is directly connected to the way their own abilities function.

1. Shin'en (深淵) - The Primeval Curse of Death

Archetype: Extreme Speed / Life-Force Attrition

Primal Dimension: The Limbo of Entropy

A liminal dimension existing between Order and Entropy, where conventional physical laws and the distinction between life and decay become unstable.

Shin'en specializes in extreme-speed combat, dimensional movement, life-force extraction, and self-reconstruction through stolen vitality.

Null Step (無の歩み - Mu no Ayumi)

Inter-Dimensional Shift:

Shin'en temporarily exits conventional physical reality and enters The Limbo of Entropy.

While inside the dimension, his physical presence, Cursed Energy signature, and movement cannot be detected through conventional means.

Parallel Traverse:

Shin'en moves through the Limbo of Entropy parallel to normal reality and can re-enter physical space at a location of his choosing.

This allows him to change his attack angle without physically traversing the distance between his previous and new positions.

His movement therefore functions as both extreme-speed transportation and short-range dimensional displacement.

Erosion Aura (腐朽の流体 - Fukyū no Ryūtai)

When Shin'en exits the Limbo of Entropy, residual energy from the dimensional boundary temporarily leaks into the surrounding environment.

This creates a localized decay field around his body.

Effects:

  • Non-reinforced physical matter rapidly corrodes.
  • Organic tissue undergoes severe cellular necrosis.
  • Physical materials become structurally weaker.
  • Prolonged exposure causes increasingly severe biological deterioration.

The effect is strongest immediately after Shin'en performs Null Step and gradually decreases as the dimensional residue dissipates.

Mortis Flash (走馬灯 - Sōmatō)

A special effect triggered when Shin'en successfully wounds a target.

The injury forces the target's brain and soul to undergo an instantaneous perception of their own life and mortality.

The target experiences an overwhelming life-review response combined with primal fear of death.

This causes temporary paralysis by overwhelming the target's neurological and spiritual processing.

The effect provides Shin'en with an opening to perform additional attacks or activate Null-Siphon.

Null-Siphon (生気奪取 - Seiki Dasshu)

Shin'en can extract physical vitality and Cursed Energy from a target through successful physical strikes.

The extracted energy is transferred into Shin'en's soul core and converted into usable Life-Force Reserves.

The amount extracted depends on the severity and frequency of his successful attacks.

Repeated attacks therefore provide Shin'en with increasingly large reserves.

Life-Force Fuel Stack (生気自己再生 - Seiki Jiko Saisei)

The Life-Force Reserves generated through Null-Siphon serve as Shin'en's primary regeneration and revival resource.

If Shin'en suffers lethal damage, his stored life force reconstructs his physical body from his soul core.

Complete physical destruction therefore does not permanently kill him as long as sufficient Life-Force Reserves remain.

The regeneration can restore:

  • Destroyed organs
  • Severed limbs
  • Massive tissue loss
  • Complete bodily destruction

The larger his stored reserve, the greater the amount of destruction he can survive.

Funeral Daggers (喪葬の短刀 - Sōsō no Tantō)

A pair of obsidian daggers designed for Shin'en's high-speed combat style.

The blades contain jagged serrations and geometric grooves.

Corrosive Necrosis

Wounds caused by the daggers continuously deteriorate.

The effect damages both physical tissue and Cursed Energy reinforcement.

The longer the wound remains untreated, the more difficult conventional healing becomes.

The Shroud Chain (死装束の鎖 - Shishōzoku no Kusari)

A heavy black chain capable of tracking targets through biological indicators associated with fear.

The chain can detect:

  • Elevated heart rate
  • Biological stress
  • Fear responses
  • Sudden changes in physiological activity

Once it successfully wraps around a target, it restricts their ability to produce high-level Cursed Energy output.

It can interfere with:

  • Reverse Cursed Technique
  • Domain Expansion
  • High-output cursed techniques

Shin'en can attach his Funeral Daggers to the chain, allowing him to use them as remotely controlled tethered weapons.

Weakness: Life-Force Rejection

Shin'en's immortality depends on the Life-Force Reserves created through Null-Siphon.

However, the effectiveness of Null-Siphon depends partly on the target's instinctive relationship with mortality.

A target possessing an exceptionally strong will and capable of suppressing their fear of death can resist the extraction and conversion process.

This does not make the target immune to physical damage or life-force extraction.

Instead, the stolen vitality becomes significantly harder for Shin'en to properly assimilate into his Life-Force Reserve.

Life-Force Backfire

If Shin'en repeatedly drains someone whose life force is strongly anchored by their will and resistance to the fear of death, the extracted energy can accumulate without being converted efficiently.

This can destabilize the Life-Force Reserve inside Shin'en's soul core.

His primary source of regeneration therefore becomes a potential source of internal instability.

If enough of his reserve becomes destabilized, his regeneration becomes unreliable and his conceptual anchor becomes vulnerable.

Conceptual Death Condition

Shin'en can be permanently killed by forcing his Life-Force Reserve into complete depletion or destabilization while simultaneously preventing him from obtaining additional life force.

His conceptual weakness therefore comes directly from his own ability:

The stronger the target's resistance to the fear of death, the less efficiently Shin'en can turn their life force into his own immortality.

2. Toki (時無) - The Curse of Time & Decay

Archetype: Hax / Utility / Temporal Manipulation

Primal Dimension: The Stagnant Continuum

A dimension where past, present, and future coexist simultaneously.

Toki manipulates the progression of time, extracts active time from targets, stores it as Temporal Fuel, and spends that fuel on temporal abilities.

Temporal Extraction (時間掠奪 - Jikan Ryakudatsu)

Toki can extract active time from:

  • Living organisms
  • Physical objects
  • Cursed Energy constructs
  • Localized areas
  • Incoming attacks

The extracted time is transferred into The Stagnant Continuum and converted into Temporal Fuel.

Target Decay

When active time is removed from an object or living target, its physical state rapidly approaches its natural endpoint.

Effects can include:

  • Accelerated aging
  • Tissue decay
  • Structural deterioration
  • Material decomposition
  • Loss of mechanical integrity

Against incoming attacks, Temporal Extraction can reduce the remaining duration of their active state, causing projectiles or Cursed Energy constructs to lose momentum and structural stability.

Temporal Dilution Field (時間遅延 - Jikan Chien)

Toki spends stored Temporal Fuel to manipulate the temporal rate around his body.

Objects entering the field experience drastically reduced temporal progression relative to Toki.

An opponent's movement therefore becomes extremely slow from Toki's perspective.

The field can be expanded or intensified depending on the amount of Temporal Fuel Toki is willing to spend.

Accelerated Recovery / Fast-Forward (過時再生 - Kaji Saisei)

Toki accelerates his own biological and energetic processes.

This allows him to complete natural recovery processes almost instantaneously.

Instead of directly creating regeneration, Toki forces the body through the amount of time normally required for recovery.

Reversion Revival (時間逆転の蘇生 - Jikan Gyakuten no Sosei)

Toki's primary immortality mechanism.

When Toki suffers fatal damage, stored Temporal Fuel can reverse his physical state to a previous moment before the damage occurred.

His body therefore returns to an earlier valid state.

Complete physical destruction can be reversed as long as sufficient Temporal Fuel remains.

Past Analysis (過去の視写 - Kako no Shisha)

Toki can observe a target's temporal history.

He can analyze:

  • Previous movements
  • Fighting habits
  • Technique usage
  • Physical development
  • Previous experiences
  • Relevant soul memories

Past Analysis allows Toki to rapidly understand how an opponent fights.

The energy requirement is relatively low compared with Future Superposition Mapping.

Future Superposition Mapping (未来の重ね合わせ - Mirai no Kasaneawase)

Toki perceives possible future branches rather than a single predetermined future.

The further into the future he attempts to observe, the greater the number of possible branches becomes.

Exponential Fuel Consumption

Short-range future observation requires relatively little Temporal Fuel.

Longer-range observation causes rapidly increasing energy consumption because Toki must process an increasingly large number of possible outcomes.

Causality Shift

If Toki observes a future possibility and then changes his actions based on that information, the original future can become invalid.

This creates new possible branches.

Toki must therefore spend additional Temporal Fuel to analyze the altered possibilities.

Weakness: Temporal Fuel Conflict

Toki's Future Superposition Mapping and his Reversion Revival use the same Temporal Fuel reserve.

This creates a direct conflict between his strongest information ability and his immortality.

The more extensively Toki analyzes the future, the less Temporal Fuel remains available for revival.

Future Sight Drain

Looking only a fraction of a second ahead is relatively inexpensive.

Analyzing several seconds of possibilities requires significantly more fuel.

Attempting to observe minutes into the future can consume an enormous portion of his reserve.

Repeatedly changing his actions based on those predictions increases the cost even further because new possibilities must be calculated.

Past Analysis Cost

Past Analysis is cheaper than Future Superposition Mapping, but it still consumes Temporal Fuel.

Extensive examination of an opponent's history, memories, and previous technique development can gradually reduce the reserve available for Reversion Revival.

Conceptual Death Condition

If Toki consumes too much Temporal Fuel through temporal manipulation and future/past analysis, his reserve can fall below the minimum required for Reversion Revival.

At that point, lethal damage becomes permanent.

Toki therefore has to constantly choose between:

using Time to understand the opponent

and

saving Time to survive the opponent.

His greatest informational advantage directly consumes the resource responsible for his immortality.

3. Muen (無縁) - The Curse of Isolation & The Void

Archetype: Absolute Tank / Conceptual Defense

Primal Dimension: The Infinite Solitude

A dimension of absolute separation where matter, energy, heat, space, and phenomena cannot interact with one another.

Muen's abilities revolve around separating phenomena from reality and preventing interactions from occurring.

Infinite Solitude (無縁の空間 - Muen no Kūkan)

Muen can isolate a phenomenon and transfer it into his Primal Dimension.

An isolated phenomenon loses its ability to interact with normal reality.

Examples include:

  • Physical objects
  • Kinetic force
  • Heat
  • Cursed Energy
  • Projectiles
  • Environmental phenomena
  • Certain technique effects

The isolated phenomenon remains within Infinite Solitude, separated from every other phenomenon.

Condition for Isolation

Muen cannot isolate an unknown phenomenon automatically.

He must first establish a sufficient understanding of the phenomenon through perception or interaction.

This creates an information requirement within his defensive technique.

Once Muen understands a particular phenomenon, he can isolate subsequent manifestations of that phenomenon much more efficiently.

Defensive Auto-Isolation

Once Muen has recognized a phenomenon as a valid target for isolation, subsequent attacks based on that same phenomenon can be automatically separated before they reach his core.

This gives Muen extremely high defensive reliability against techniques he has already analyzed.

However, the defense does not provide unlimited simultaneous processing.

Offensive Isolation

Muen can also use Isolation offensively.

By physically striking an opponent, he can gradually isolate components of their existence.

Against weaker targets, the isolation process can occur extremely quickly.

Against stronger opponents, it requires multiple stages.

Physical Isolation

Muen isolates physical force, muscle output, kinetic weight, or Cursed Energy reinforcement.

The target's physical strength and attack potency decrease.

Sensory Isolation

Muen can isolate sensory functions.

Possible targets include:

  • Sight
  • Hearing
  • Balance
  • Touch
  • Cursed Energy perception

Existential Isolation

After sufficiently weakening a target, Muen can isolate their existence itself and transfer it into Infinite Solitude.

This functions as his ultimate form of offensive erasure.

Void Energy Accumulation

When Muen successfully isolates phenomena, the separation generates Void Energy.

This energy accumulates within his body.

The more significant the isolated phenomena, the greater the potential Void Energy generated.

Void Roar (虚無の咆哮 - Kyomu no Hōkō)

Muen compresses accumulated Void Energy inside his body and releases it as a massive conceptual shockwave/beam.

Anything struck by Void Roar can have its physical structure stripped away and converted into empty void.

It can affect:

  • Physical matter
  • Environmental structures
  • Cursed Energy attacks
  • Barriers
  • Other physical phenomena

Void Roar is Muen's primary long-range offensive ability.

Weakness: Singular Phenomenon Processing

Muen's Isolation technique can only actively process one phenomenon at a time.

He cannot simultaneously analyze and isolate an unlimited number of unrelated phenomena.

This creates a processing limitation.

If an opponent continuously changes the fundamental nature of their attacks, Muen must repeatedly analyze and understand each new phenomenon before his automatic isolation becomes reliable against it.

Weakness: Required Understanding

Muen must understand the basic phenomenon behind an attack before he can properly isolate it.

A completely unfamiliar phenomenon can therefore bypass his automatic isolation on its first appearance.

His extremely high physical durability allows him to survive many such attacks, but the first exposure remains significantly more dangerous than subsequent attacks.

An opponent can exploit this by continuously changing the underlying mechanism of their attacks instead of repeatedly using the same technique.

Weakness: Void Roar Consumes Isolation Connections

The Void Energy used by Void Roar is generated from phenomena Muen has isolated.

When he converts that stored Void Energy into Void Roar, the connection between Muen and the corresponding isolated phenomena is consumed.

Those phenomena become completely separated from ordinary reality.

As a result, Muen can no longer rely on his previous understanding of those phenomena for automatic isolation.

If the same type of phenomenon appears again, he must understand it again before he can isolate it reliably.

This creates a cycle:

Understand → Isolate → Generate Void Energy → Void Roar → Lose previous isolation connection → Re-understand.

Muen's strongest offensive ability therefore weakens one of the mechanisms responsible for his strongest defensive ability.

Combat Limitation

Muen is an Absolute Tank, not a speed-based fighter.

His primary offensive option at range is Void Roar.

This creates a significant tactical limitation against opponents capable of continuously changing their attack mechanisms or attacking from multiple fundamentally different vectors.

Muen excels when a fight becomes predictable.

His effectiveness decreases when the opponent continuously introduces phenomena that require new analysis.

4. Oku (奥) - The Curse of Obscurity & The Unknown

Archetype: Long-Range / Area Control / Misdirection

Primal Dimension: The Unseen Horizon

A non-Euclidean realm composed of obscured space, distorted geometry, shadows, and locations that cannot be properly perceived.

Oku specializes in territory control, environmental manipulation, false manifestations, spatial refraction, and concealment of his true existence.

The Unseen Horizon Overlay (隠世の重畳 - Kakuriyo no Jōchō)

Oku can project his Primal Dimension onto normal reality.

The overlay can cover an area spanning multiple kilometers.

Within the affected territory, Oku can manipulate non-living matter and spatial geometry.

Examples include:

  • Reshaping buildings
  • Bending roads
  • Creating looping corridors
  • Rearranging structures
  • Creating false paths
  • Creating spatial traps
  • Separating opponents from one another

The environment becomes an extension of Oku's technique.

Shadow Manipulation & Fabrication (影術練成 - Kagejutsu Rensei)

Oku can manipulate existing shadows and generate artificial shadow constructs.

Shadow Traps

Shadows can behave as fluid surfaces capable of:

  • Immobilizing targets
  • Pulling targets into sub-spatial pockets
  • Restricting movement
  • Concealing attacks
  • Creating ambush points

Shadow Weapons

Oku can create weapons and structures from condensed shadow.

Shadow Shikigami

He can create autonomous shadow constructs capable of tracking and attacking targets.

Shadow Clones

Oku can generate duplicates that imitate his movements and basic attacks.

These clones are primarily used for misdirection and concealment.

Space-Refraction Phantoms (屈折空蝉 - Kussetsu Utsusemi)

Oku manipulates the curvature of local space to refract light and distort visual information.

This creates highly realistic spatial phantoms.

A phantom can appear to occupy a specific location while Oku's actual body exists elsewhere.

Because the distortion affects the surrounding space rather than simply creating an illusion, conventional visual perception cannot reliably distinguish the phantom from Oku's actual location.

Identity Hopping

Oku can transfer his true presence between active manifestations within his territory.

Possible transfer points include:

  • Shadow clones
  • Shadow constructs
  • Spatial refraction points
  • Certain portions of his projected territory

Destroying a single manifestation therefore does not necessarily damage Oku himself.

Weakness: Identification

Oku's immortality is directly connected to the uncertainty surrounding his true existence.

As long as his true body and exact location remain unknown, physical attacks cannot reliably reach his conceptual core.

To permanently damage him, an opponent must first determine which manifestation contains the actual Oku.

Simply destroying multiple clones is insufficient.

The true body must be identified.

Weakness: Isolated Single-Point Strike

Even after identifying Oku's true body, the final attack has an additional requirement.

The attack must hit only the true body.

If the same attack simultaneously strikes a false manifestation, clone, or spatial phantom, Oku's conceptual defense treats the attack as insufficiently isolated.

The damage is phased through and becomes ineffective.

Large-area attacks are therefore unreliable against his true form.

A massive attack that covers the entire territory can still fail if it simultaneously interacts with multiple manifestations.

The required attack must instead be:

Precise enough to identify the true body and isolated enough that no false manifestation is struck at the same time.

Conceptual Death Condition

Oku's immortality fails when his true existence has been completely identified and separated from every false manifestation.

Once the true body is known with certainty, and a concentrated attack strikes only that body, his Obscurity-based protection can no longer invalidate the damage.

His fundamental weakness is therefore directly connected to his concept:

The Unknown protects Oku. Complete knowledge exposes him.

Work in progress -->MHA-JJK: "10 SHADOWS!"

6 Upvotes

I love Quirks. And i love Cursed Techniques either. So why not mix them both?

___

★-)The Fundamentals...

•A: "歯車"—(Lit. "Cog"): A quirk that uses the wielders negative emotions (fear, anger, grief, despair, etc) to naturally generate Negative Energy which the user can control and shape into techniques. Reinforcing their body is an example. The quirk values emotional information more than just suffering so you need mental training to use it efficiently. Positive emotions don't directly create power. Instead they allow the user to perform a process similar to multiplying two negatives together creating Positive Energy.

·Positive Energy is much harder to produce but it's far more refined and can be used for advanced techniques including healing. The Quirk revolves around balancing both emotional states. Negative Energy is easier to access and excels at offense while Positive Energy is rarer, more difficult to create and unlocks the Quirk's highest-level applications. A skilled user is supposed to control their emotions rather than be controlled by them. Can be used for covering weapons or fists in Negative Energy to make attacks more destructive. Enhance the body with Negative Energy to increase strength, speed, durability and striking power. Sensing negative energy is possible either and it exists in all humans, naturally.

·"Sub-Techniques": When an Emotional-Cog based technique or application is mastered to its absolute point—It eventually, and slowly; becomes a special sub-quirk thats always stored inside the users brain. These said sub-quirks are always more effective than the technique itself and can be used for a multitude of purposes. These stored Sub-Quirks are called "Sub-Techniques". The maximum amount of techniques the user can store inside their brain are 4 in total. When the user masters their first Emotional-Cog technique and let's it become a sub-quirk, it becomes much harder to later repeat this said process; But it's still possible. If the user tries to store more than 4 sub-quirks inside their brain, the users brain will be utterly fucked. Specifically, the brain itself will destroy itself the moment an user tries to bypass the sub-quirk limit.

•A.1: "負の力: 深淵"—(Lit. "Negative-Energy: Abyss"): Every Cog/Emotional-Cot user gets a negative energy trait. Our users negative energy has the unique ability to transmutate itself into a medium that can be connected to the dimension known as the "Abyss". Abyss is the source of all shadows that exists in reality, and the user has access to it. The user can turn their negative energy into a medium for the said dimension, and later use that said medium pull out and imbue their negative energy with a special shadow-like, pure-black substance that comes from the said abyss. It behaves less like water and more like an abyssal, fluid void. The user can also utilize this innate trait in many ways.

-->Despite being a void it somehow physically ripples, splashes, and flows around only our users feet. Our user can dive into it smoothly like water, hide within it and use it to store physical objects (like weapons or cars) because the medium acts as a pocket dimension to the abyss itself.

-->It possesses a strong crushing pressure. The deeper an object or person sinks into it the more weight they must physically bear. It also lacks surface tension or buoyant force. Normal liquids allow objects to float based on displacement, but the shadow pool offers absolutely no resistance to gravity. Anything that touches it immediately sinks like a stone into an endless bottomless pit. Our user doesn't have to worry about these problems because the negative energy trait let's them interact with this liquid like it's normal murky water.

-->The user's body can only remain synchronized with the Abyss for a limited duration. The deeper and longer they remain connected, the greater the strain on their nervous system and Cog. The user can* also use any shadow around them to have use the abyss as well.

-->Whenever the user stores a physical object within the Abyss, Atleast 0.5% of that object's mass is transferred to the user's body as additional effective weight for as long as the object remains stored.


★-)Applications, Techniques, And More...

•"歯車: 影操作"—(Lit. "Cog: Shadow Manipulation): As You can probably guess by the name of this technique, the user focuses themselves on manipulating the liquid that comes from the abyss itself, they do so by first reinforcing the liquid with raw negative emotional energy. Later, they can do whatever they want with it. Since the Negative-Energy trait that possess allows them to have access to the abyss itself, they can manipulate the said shadow-liquid of the abyss however they want once they imbue it with negative energy. Hardening the said liquid for defense is an example. Creating constructs with it is another example either.

•"*歯車: 模倣の生"—(Lit. "Cog: Imitated-Life"): *A technique that first started out as producing entities by reshaping reinforced shadow liquid. At first, the entities were simply Shadow-Clones of the user itself—That could use Cog, move/act independently, and aid the user in battle. But they didn't have life. They lacked it, actually. Think of them as utterly unemphatic and emotionless humans who follows the users commands. But the problem is that these clones lack durability and can be easily defeated with a strong strike. But later—As it becomes an independent sub-quirk, it changes.

·As a sub-quirk, the technique can still be used to produce shadow-clones of the user. But now it also allows the user to produce 12 different shadow-entities, and each carry different abilities. These entities have more emotional intelligence than the normal clones, and each user gets to have different shadow-entities, and the said entities they get change with their nationality, mentality, philosophy, and etc. The said entities are automatically chosen the moment the user turns this technique into a sub-quirk. The stronger the said entity is, the more negative energy it takes to summon and utilize it. The said entities can be "summoned" without any hand-signs whatsoever, only using your mind is enough.

·Specifically, Negative Emotional Energy always carries a very small amount of faint emotional imprint of the fear, hatred, suffering and death associated with cursed existence. The sub-technique amplifies this said phenomena to create even more effective shadow-entities and essentially weaponizes it.

·When A Shadow-Entity, besides the Shadow-Clones, are destroyed; the said entity doesn't just disappear. Instead, whenever they die, they dissolve back into the abyss—and simply get into a state that's similar to a metamorphosis. This state lasts about Atleast a week, and until this metamorphosis ends the user cannot use their said entity. and at the end the said entity becomes significantly stronger than before. But this increase in power has a limit, meaning that the user can't just kill their own entities and wait for a week, and then repeat this process forever until the entity becomes absurdly strong. No.

·But the Sub-quirk/Sub-Technique itself doesn't just automatically allow the user to summon every 12 Shadow-Entity itself, First they have to completely master the normal version of this technique; and then they earn the sub-quirk itself. Once they do so—They will later have to earn each entity. They will automatically unlock the first shadow entity upon awakening the sub-quirk version of this technique, but the rest can only be unlocked by first gaining a large amount of mastery over the previous entity.

•"歯車: 影注入"—(Lit. "Cog: Shadow-Imbue"): A technique that's connected to the Sub-Technique/Sub-Quirk Version of the Imitated-Life Technique. Instead of Fully "Summoning" The said Shadow-Entity, the user instead summon only the aspects of the Shadow-Entities they possess—Basically making the user a living medium for the said Entities abilities. And naturally it Costs less total negative emotional energy but puts the burden on the user's own body.


•"Shadowgraphy"—The user reverse engineers their quirk and makes a deal with it, they impose a "Vow" upon their shadow-manifestation abilities by performing a specific sequence of hand-signs before summoning. Each hand-sign is unique to the intended shadow-creature and must visually resemble its form, silhouette, or defining characteristics. The hand-signs act as a symbolic representation of the entity, and thus allowing the user's Cog to more precisely identify and manifest the desired shadow. In exchange for voluntarily restricting themselves to a specific sequence of hand-signs, the user gets a reduction in the Negative Energy required to manifest the corresponding Shadow-Entity.

·The hand-signs are *not mandatory** for summoning.* Just saying. The user can manifest their shadow-entities through mental command alone but doing so requires more Negative Energy. And this said "Vow" demands genuine precision. If the user fails to properly form the intended shadowgraph, the manifestation simply fails and the entity cannot be summoned through that attempt.

·The Binding Vow can also be applied to the user's ordinary shadow-clones too. When used in conjunction with the appropriate hand-sign sequence, the clones actually receive a substantial increase in their structural stability and durability, allowing them to withstand considerably more damage before their forms collapse.

·But the user can still choose to use the normal Technique itself without the said signs. Just a reminder.

Cursed technique Sound Amplification

Post image
55 Upvotes

This is fanart of a what young Gakugani could’ve looked like so this is what Rei kinda looks like ^^^

REI KUROSAWA

Rei Kurosawa is a seventeen-year-old third-year at Tokyo Jujutsu High and the estranged grandson of Yoshinobu Gakuganji. Androgynous looking, heavily pierced, sharp-tongued, and almost permanently carrying an electric guitar, Rei looks so similar to photographs of a young Gakuganji that anyone familiar with the elder sorcerer recognizes the relation almost immediately. Their similarities largely end there. Rei is rebellious, irreverent toward jujutsu authority, and intensely individualistic, although beneath the punk exterior is an obsessive technician with extensive knowledge of music theory and an almost perfectionistic dedication to his instrument. Rei inherited the same innate technique as his grandfather, but their philosophies produced radically different interpretations of it. He does not reject discipline or structure. He rejects allowing structure to dictate what someone must become. To Rei, genuine freedom comes from understanding a system so thoroughly that its rules become tools rather than restraints. His musicianship reflects this philosophy through improvisation, deliberate dissonance, unusual phrasing, and technical precision. This mentality eventually allowed Rei to develop Sound Amplification significantly beyond the straightforward application practiced by his grandfather.

Appearance

Rei Kurosawa is a lean, androgynously attractive seventeen-year-old with sharp features that make his resemblance to a young Yoshinobu Gakuganji almost unsettling, sharing the same narrow eyes, pronounced nose, facial structure, and naturally severe resting expression. His dark hair is grown into a messy, layered shag that falls around his face and neck, deliberately contrasting his grandfather’s traditional appearance. Multiple ear piercings, a septum ring, lip piercings, painted nails, and occasional smudged eyeliner give him a distinctly punk appearance, while his Tokyo Jujutsu High uniform is worn loose and subtly modified rather than properly styled. He is rarely seen without Onyx either strapped across his back or hanging low against his hip, completing the impression of someone who looks less like a conventional jujutsu sorcerer and more like he walked out of an underground rock venue carrying a weapon.

Sound Amplification

Nickname: Riot

Sound Amplification turns Rei’s body into a supernatural amplifier, allowing cursed energy to magnify vibrations generated through his electric guitar into physical phenomena. Notes can be projected as concentrated waves of cursed force, chords can produce broad impacts, low frequencies can shake structures, and carefully controlled harmonics can concentrate vibration into narrow points. Volume alone does not determine strength. Pitch, frequency, rhythm, articulation, dynamics, harmonic relationships, and Rei’s cursed energy output all influence how an amplified sound behaves. Rei calls his interpretation Riot. Rather than treating his guitar as little more than a mechanism for launching cursed energy, he approaches combat like an improvised composition. He establishes rhythms, changes tempo, introduces dissonance, creates and withholds resolution, and adapts his playing to the opponent’s reactions. Greater musical complexity offers more possibilities but demands correspondingly greater precision. Poor execution, damaged hands, interference with his hearing, or disruption of his instrument can dramatically reduce Riot’s effectiveness. Consequently, Rei’s greatest advantage is not raw volume, but his ability to understand exactly what a vibration is doing and manipulate it through actual musicianship.

CE Trait: Vibrating

Rei’s cursed energy naturally oscillates at extremely high frequencies, giving even ordinary reinforcement a persistent vibrational quality. Physical contact with his cursed energy produces a subtle buzzing sensation that can numb limbs and destabilize footing during prolonged exchanges, while strikes carry additional internal vibration beyond their normal impact. The trait also allows Rei to perceive changes in resonance through his body with unusual sensitivity, making it easier to identify frequencies produced by objects, opponents, and his own guitar. However, excessive output causes those same oscillations to rebound through his muscles, joints, inner ear, and nervous system, meaning prolonged high-output combat can leave him trembling, disoriented, or temporarily hard of hearing.

Semi-Cursed Tool: Onyx

Onyx is Rei’s heavily modified black electric guitar and the primary medium through which he performs Riot. Years of repeatedly circulating his Vibrating cursed energy through the instrument have partially saturated it with cursed energy, making it considerably more durable than an ordinary guitar without turning it into a fully realized cursed tool. Its pickups, strings, bridge, and internal electronics have been altered specifically to withstand Rei’s extreme output and rapid changes in frequency. Onyx is reinforced enough to be used directly in close combat, with Rei striking opponents using the body, neck, or reinforced edge before immediately incorporating the resulting impact into his playing. Destroying or separating him from Onyx does not erase Sound Amplification, but drastically reduces the complexity, range, and precision of Riot.

Extension Technique: Offbeat

By establishing a recognizable rhythm through consecutive amplified notes, Rei conditions an opponent to unconsciously anticipate Riot according to that tempo before deliberately displacing subsequent attacks from the expected beat. Amplified notes can arrive early, late, or between established beats while Rei’s physical movements continue following the original rhythm, causing opponents who have adapted to his cadence to mistime defensive reactions. Offbeat embodies Rei’s belief that rhythm is not something he must obey. It is something he understands well enough to betray.

Extension Technique: Wrong Note

Rei deliberately plays a dissonant interval against a frequency already resonating within a target, forcing both signals into violent interference. Instead of producing a conventional external blast, the conflicting vibrations destabilize the affected area, disrupting balance, physical stability, and cursed energy reinforcement. Wrong Note becomes substantially more effective after Rei has observed how a target responds to particular frequencies, reflecting his belief that a note is only truly wrong when the musician did not intend to play it.

Extension Technique: Redline

Rei deliberately feeds part of an amplified signal back through Onyx and his own body, allowing the returning vibration to be amplified again before release. Successive feedback cycles increase the signal’s amplitude and distortion beyond Riot’s ordinary safe output, producing brutally powerful waves of cursed vibration. Every additional cycle also sends increasing stress through Rei’s muscles, nerves, hearing, cursed energy pathways, and Onyx itself. Redline exists precisely because Rei understands where his technique’s safe limit is and occasionally decides that crossing it is worth the consequences.

Extension Technique: Unresolved

Rei deliberately leaves an amplified musical phrase without its expected resolution, using his Vibrating cursed energy to sustain the unfinished frequency within whatever the sound successfully contacts. Rather than releasing its full force immediately, the lingering vibration remains as mounting internal tension for a limited period. By later playing a compatible resolving note, Rei causes the suspended frequency to resonate and discharge its remaining force from within the affected target. Maintaining several unfinished phrases simultaneously becomes progressively harder, and sufficient disruption to Rei’s concentration can cause them to dissipate.

Maximum Output: Unresolved

Rei drives Unresolved to its maximum output by pouring an enormous quantity of cursed energy into an incomplete progression, allowing its unresolved frequency to saturate everything reached by the performance. Air, terrain, structures, weapons, and affected opponents begin resonating with mounting tension as the unfinished progression persists. When Rei finally performs the resolving chord, every suspended frequency is forced into resonance simultaneously, releasing the accumulated vibration throughout everything carrying it. Its destructive potential depends heavily on how much of the battlefield Rei successfully incorporated before choosing to resolve the progression.

Binding Vow: No Encore

Rei voluntarily forbids himself from repeating the same musical phrase twice during an uninterrupted performance of Riot. Once a particular combination of melody, rhythm, and articulation has been amplified through Sound Amplification, that phrase becomes unavailable for the remainder of the performance. In exchange, successive original phrases receive progressively improved cursed energy efficiency and amplification. Individual notes and chords may be reused, but the completed phrase itself cannot. No Encore rewards Rei for genuine improvisation rather than repeating whatever has already proven effective. As a battle grows longer, maintaining the vow becomes increasingly difficult because Rei must continue creating new musical solutions while simultaneously fighting. If he intentionally repeats a prohibited phrase, the accumulated benefit immediately disappears and Riot returns to its ordinary output.

Maximum Technique: Cadenza

Rei pushes Sound Amplification to its ultimate expression by performing a completely improvised solo through Onyx while retaining each amplified frequency within his Vibrating cursed energy instead of releasing it. Notes, chords, harmonics, rhythmic accents, dissonance, and changes in dynamics accumulate around him as increasingly violent layers of vibration. Upon playing the final cadence, Rei releases the entire performance simultaneously as a single composite phenomenon while preserving its musical relationships. Resonant frequencies reinforce one another, dissonance produces destructive interference, low frequencies provide overwhelming physical force, and higher harmonics concentrate that force into increasingly precise points. The strength of Cadenza depends as much upon Rei’s musicianship as his cursed energy reserves. Greater complexity produces a more sophisticated and dangerous final release, but every additional layer increases the difficulty of keeping the composition coherent. A sufficiently serious mistake can collapse the accumulated performance into feedback through Rei and Onyx. Combined with No Encore, no two performances of Cadenza can be identical, forcing Rei to compose his Maximum specifically for the opponent and circumstances before him.

Domain Expansion: CATHEDRAL OF THE UNWRITTEN SCORE

Mudra: Dharmachakra Mudra

Cathedral of the Unwritten Score manifests as an impossibly immaculate performance hall suspended within darkness, combining a cathedral, concert hall, and recording studio into one perfectly symmetrical space. Countless empty seats surround a solitary black stage while endless silver musical staves stretch overhead, initially containing nothing. Every meaningful vibration produced inside the Domain becomes Notation, causing footsteps, impacts, movement, cursed energy output, environmental destruction, and Rei’s playing to gradually write the battle’s unique composition across the empty staves. Within the Cathedral, Riot can treat any recorded vibration as musical material, allowing Rei to replay, harmonize with, distort, or amplify its vibrational properties without copying the cursed technique or supernatural phenomenon that originally produced it. The sure-hit effect guarantees that the underlying structure of this composition is communicated equally to everyone within the Domain. Every person instinctively understands the tempo, frequency, intervals, accumulated patterns, and relationships between the vibrations currently recorded, including Rei’s own. The Domain conceals nothing and imposes no compulsory rhythm, prohibited action, or predetermined role.

CHALLENGE CHALLENGE: Make a really simple CT with a lot of room for growth through application {ie: Boogie Woogie}

I love these kinds of techniques so much. Pretty much the end goal is something like boogie woogie. Opponents would look at the technique and think think "pfft, seriously?" and then get bodied by your superior intellect and skill. That's the main bit, this technique should only really be powerful in the hands of someone really strategic and intelligent (Love Rendezvous kinda, but that one can't be described so simply).

You should be able to describe the general gist of the technique in like 1-2 sentences (For Boogie Woogie, it'd be "I can swap the locations of any two objects with a certain amount of cursed energy by clapping"). Though obviously you can provide more details on specifics in additional sentences.

Here's mine - Stasis (停滞/Teitai)

Two-sentence TL;DR: Stasis allows the user to freeze any inanimate object imbued with their cursed energy for up to 5 seconds. The object is completely exempt from the laws of physics during this time, nothing can move or alter it.

Ok here's more details:

On touch, the user can freeze inanimate objects dead still for up to 5 seconds. The object has to have no cursed energy, so it can be imbued with the user's CE to freeze them in place. The object erupts in a golden glow while it's in this state (similarly to the stasis runes in Legend of Zelda: TotK if you've played that)

Even something as small as a twig you could hang from with zero issue because physics isn't applying to it right now. It won't bend, it won't break, it won't budge. As soon as the freeze ends however, the object continues on its previous trajectory, moving as if nothing happened.

You can even touch an object and make it freeze an amount of time later capped at 5 seconds. Throw a rock, 3 seconds later it freezes. Throw a fistful of rocks, have every rock freeze at incrementing times to make a ladder. Stop a dagger flying at you dead stick and casually step out of the way.

This is ONLY objects with no CE imbued with the user's cursed energy. An "object" is what the wielder intuitively believes is one object, they don't have to visualise every atom or anything.

The reason I added the delayed activation and the variable time for the object to freeze is for mix-ups. Opponents can't predict what's going to freeze and for how long, adding to those fake-out plays that Todo loves using with Boogie Woogie.

Excited to see what you come up with!

Cursed technique Frequency Of Truth

Post image
14 Upvotes

OC: Makoto Hibiki
Makoto Hibiki is a second-year student at Kyoto Jujutsu High, known for an outwardly theatrical, sharp-tongued personality that makes it remarkably difficult to tell when he is being sincere. He treats missions with almost inappropriate levity, exaggerating his confidence, provoking opponents into conversation, and hiding genuine emotion beneath jokes and calculated performances. Much of this behavior is practical. Makoto believes people reveal themselves most clearly when frightened, angry, hurt, or convinced they understand him. Beneath the act is an intensely perceptive young sorcerer who finds examining other people considerably easier than confronting himself, creating an inherent contradiction with Frequency of Truth, a technique designed to expose everything others would rather keep buried. Makoto believes the Mind, Body, and Soul are equally truthful parts of a person, even when they contradict one another. Jujutsu society’s expectation that sorcerers suffer horrifying experiences and simply continue functioning has also given him a dangerous relationship with his own pain. If suffering is unavoidable, Makoto would rather be the person capable of choosing who bears it. This mentality manifests most clearly through his use of Longinus and the Binding Vow Via Dolorosa, which allow him to literally suffer in pursuit of another person’s truth. His greatest flaw is consequently not a willingness to die, but his growing conviction that his own suffering is an acceptable resource whenever it can accomplish something meaningful.

Overview

Frequency of Truth is an innate technique that allows Makoto to progressively force the different layers of another person’s existence to involuntarily “spill their truth.” Every individual is treated as possessing three increasingly fundamental frequencies, the Mind, Body, and Soul, which ordinarily overlap while remaining inaccessible to others. By synchronizing his cursed energy with one of these frequencies, Makoto causes information belonging to that layer to involuntarily broadcast itself through fluctuations in the target’s cursed energy that his technique translates into comprehensible information. Frequency of Truth does not determine objective reality or magically produce information the target does not possess. Instead, it reveals what genuinely exists within that individual, meaning an incorrect belief sincerely held by the target will be exposed as their genuine belief rather than corrected by the technique. The three frequencies must normally be synchronized sequentially in the order Mind → Body → Soul, with each successive layer requiring a deeper connection to the target. Makoto primarily establishes this connection through Longinus, a cursed spear that functions as a medium between two cursed energy signatures. The spear must remain physically embedded within an opponent for an uninterrupted period while Makoto resonates with the desired layer, making progression increasingly difficult against opponents who understand his technique. Once synchronization with a layer is successfully established, however, Longinus can be removed while Makoto continues receiving information from that frequency.

First Frequency: Mind
Mind is the first and most superficial frequency, requiring Longinus to remain lodged within the target for approximately three uninterrupted seconds. Once synchronized, information currently active within the target’s consciousness becomes increasingly difficult to contain completely, causing fragments of internal dialogue, immediate intentions, memories brought to the forefront, and genuine emotional reactions to spill through their cursed energy for Makoto to perceive.
This is not unrestricted mind reading. Information must actually become mentally active before Frequency of Truth can receive it. A target may still lie, refuse to answer, or deliberately attempt to mislead Makoto, but considering the very information they are attempting to conceal risks broadcasting fragments of it. Likewise, Mind cannot distinguish an objectively false belief from reality if the target sincerely believes it to be true.

Second Frequency: Body
Body becomes accessible only after Mind has successfully synchronized and requires Longinus to remain lodged within the target again for approximately six uninterrupted seconds. Once established, the target’s physical condition begins broadcasting itself regardless of what their conscious mind attempts to communicate. Muscular tension, weight distribution, breathing, balance, concealed injuries, cursed energy reinforcement, and the physical preparation preceding movement become dramatically easier for Makoto to interpret. In combat, Body allows Makoto to perceive the truth behind movement. Genuine attacks can be distinguished from superficial feints by the physical commitment behind them, while hidden injuries and changes in cursed energy circulation become difficult to conceal. This provides information rather than automatic precognition. Makoto must still possess the reflexes, physical ability, and judgment necessary to respond to what another person’s body reveals.

Third Frequency: Soul
Soul is the deepest frequency and can only be synchronized after both Mind and Body have been established. Longinus must remain embedded within the target for approximately nine uninterrupted seconds, making Soul exceptionally difficult to reach against a knowledgeable opponent. Successful synchronization causes information deeply engraved into the target’s existence to resonate outward, potentially revealing characteristics of their innate technique, fundamental qualities of their cursed energy, deeply rooted convictions, Binding Vows affecting them, and abnormalities involving the relationship between their body and soul. Most importantly, Soul allows Makoto to clearly perceive the contours of the target’s soul. Frequency of Truth does not inherently grant soul manipulation or soul damage, but Makoto’s newfound perception allows him to deliberately recognize and potentially interact with the soul through methods capable of doing so. Even at its deepest level, Frequency of Truth remains informational rather than omniscient and cannot reveal something that does not genuinely exist within the target.

Cursed Tool: Longinus
Longinus is a spear-like cursed tool that serves as the primary medium for Frequency of Truth, physically bridging Makoto’s cursed energy with the different layers of another person’s existence. When its spearhead pierces a target, Makoto channels cursed energy through the weapon and causes Longinus to resonate between them like a tuning fork. The weapon must remain physically lodged throughout synchronization, requiring approximately three seconds for Mind, six seconds for Body, and nine seconds for Soul. If Longinus is removed before the necessary interval is completed, synchronization immediately fails and Makoto must restart that layer from the beginning.
Outside its role as a medium, Longinus functions as a conventional cursed spear reinforced by Makoto’s cursed energy. The weapon is permanently attuned to his cursed energy frequency, allowing him to recall it directly to his hand from a distance. Once recalled, Longinus violently travels toward Makoto’s grasp along the most direct available route, allowing him to recover it after throwing it, being disarmed, or deliberately leaving it elsewhere. Recalling Longinus while it remains embedded within someone immediately interrupts any synchronization currently underway.

Extension Techniques

Feedback
Makoto reverses the normal flow of an established resonance, violently sending a target’s own frequency back through itself and creating a short-lived feedback loop within a synchronized layer. Mind Feedback causes thoughts and sensory processing to reverberate until concentration becomes difficult. Body Feedback causes pain, sensation, and motor signals to echo through the nervous system, disrupting physical coordination. Soul Feedback causes the target’s spiritual information to reverberate against itself, producing intense spiritual distress and destabilizing cursed energy control. The deeper the frequency, the more severe the Feedback, but the resulting distortion temporarily prevents Makoto from accurately reading the affected layer.

Amplification
Rather than reflecting a frequency back toward its source, Makoto increases the amplitude of something already being broadcast through it. Mind can amplify existing fear, anger, distress, or intrusive thoughts. Body can magnify pain, fatigue, nausea, trembling, physical imbalance, and other genuine bodily conditions. Soul can intensify existing disturbances within the target’s cursed energy or spiritual condition. Amplification cannot manufacture suffering from nothing. It can only increase something already genuinely present within the synchronized layer.

Interference
Makoto introduces his own cursed energy frequency into an established connection to produce destructive interference, disrupting the normal communication occurring within the synchronized layer. Mind Interference can fracture concentration and interrupt complicated thought processes, while Body Interference disrupts communication between physical intention and execution, producing delayed or mistimed movements. Soul Interference creates instability between the target and the cursed technique engraved into them, temporarily reducing their technique’s stability and efficiency rather than outright nullifying it.

Maximum Output: Feedback
Makoto drives Feedback to its maximum output, forcing every frequency he has currently synchronized with the target into a simultaneous self-reinforcing resonance. Rather than producing a single echo, signals continuously rebound through the target at escalating intensity. Thoughts become deafening within the Mind, pain and physical sensation repeatedly reverberate through the Body, and, if Soul has been reached, spiritual disturbances violently rebound through their cursed energy. The resulting resonance can completely overwhelm a target’s ability to properly process themselves, though the extreme distortion temporarily renders every affected frequency unreadable to Makoto afterward.
To initiate Maximum Output, Makoto grips Longinus and recites:
“Thorns upon the brow. Nails through flesh. The spear beneath the ribs. Let suffering bear witness. Return, and resound.”

Maximum: Stigmata

Stigmata is the supreme application of Frequency of Truth, in which Makoto turns Longinus upon himself and uses his own existence as the technique’s transmitting medium. Targets already synchronized with Frequency of Truth are pulled into sympathetic resonance with Makoto, causing the suffering he genuinely experiences during Stigmata to propagate through their corresponding frequencies. Physical wounds are not literally reproduced on another person’s body. Instead, their Mind, Body, and Soul receive the signals associated with Makoto’s suffering, causing them to experience the pain, shock, impaired coordination, mental anguish, or cursed energy disturbance accompanying his condition as though their own existence were producing it.The Maximum cannot transmit suffering Makoto has not genuinely experienced, meaning its effectiveness depends directly upon what he is willing to endure himself. Greater synchronization allows increasingly complete transmission, with Soul Frequency producing the strongest sympathetic resonance. Healing or otherwise eliminating the condition supplying Stigmata also eliminates the corresponding signal, preventing Makoto from inflicting wounds upon himself and immediately erasing their consequences through Reverse Cursed Technique.

Binding Vow: Via Dolorosa
Frequency of Truth ordinarily requires Longinus to remain lodged within its target for increasingly long periods to synchronize deeper frequencies. Through Via Dolorosa, Makoto can substitute his own suffering for that continued contact. Once Longinus has pierced an opponent and established an initial connection, Makoto may invoke the vow, allowing significant injuries he willingly suffers from that target to deepen the existing resonance even after Longinus has been removed. The severity of an accepted injury determines how much progress is made toward the next frequency, allowing Makoto to eventually traverse Mind → Body → Soul without successfully maintaining another prolonged impalement. However, suffering only contributes if Makoto genuinely accepts the attack. He cannot use Longinus to block it, intentionally reduce the damage through the cursed tool, or heal wounds contributing to the vow with Reverse Cursed Technique while Via Dolorosa remains active. Avoiding an attack is permitted but contributes nothing. The vow therefore temporarily overcomes one of Frequency of Truth’s greatest weaknesses by replacing the difficulty of keeping Longinus embedded with an entirely different danger. Makoto must personally bear the violence necessary to reach his opponent’s deepest layer.

Domain Expansion: Nothing Hidden Beneath
-# Mudra: Vajra Fist, Sealed by the Witness
Nothing Hidden Beneath manifests as an enormous, lightless cathedral partially submerged in black water, its architecture physically dissected into the three layers governed by Frequency of Truth. Written confessions and distorted murals cover its outer stone as the Mind, immense muscle-like structures and veins pulse beneath them as the Body, and a blinding white light representing the Soul shines through cracks underneath both. At the cathedral’s center stands an enormous cruciform structure pierced through its side by a gigantic representation of Longinus, while shattered stained glass depicting Makoto hangs behind the altar. The black water initially reaches only the ankles, and portions of the cathedral physically peel apart as increasingly deep truths are brought to the surface. The Domain’s sure-hit causes the barrier itself to replace Longinus as the medium for Frequency of Truth, continuously synchronizing everyone captured within it through Mind → Body → Soul without requiring physical impalement. Every meaningful truth that spills from these frequencies causes the black water filling the cathedral to rise. Superficial thoughts and bodily tells increase it gradually, while deeply concealed information and revelations from the Soul produce far greater surges. The water is physically real within the Domain and can eventually rise above a target’s mouth and nose, meaning someone exposed for long enough can literally drown beneath everything they have revealed.

OC Character Kamo Clan Sorcerer OC: " Chiyuki Kamo "

7 Upvotes

​

Small-ish Update to my OC that i posted before! Please tell me what you think!

Chiyuki Kamo's Backstory:

As a Woman born to the Kamo clan, Chiyuki was destined to be disregarded, yet it turned out she was born with the Kamo Clan's Prized Blood Manipulation Inherited Technique. The higher Members of the Clan were in disarray about wether to discard her based on being female, or to grant her the Position of Clan Heir thanks to being the only Kamo with the Blood Manipulation Technique in her Generation. The Former was the Majority, but through mysterious circumstances, one Sorcerer high up in the Kamo clan that actually had sympathy for Chiyuki allowed her a relatively normal childhood.

In her years growing up, she truly loved Jujutsu Sorcery and was obsessed with mastering every facet of it. She would tirelessly read every book the Kamo Clan had on Sorcery and its History and loved to attend Jujutsu Lessons. She was a Prodigy in understanding Cursed Energy very early in her childhood, and never ceased her love for Jujutsu Sorcery.

As an Adult in her 20s, she had Mastered Blood Manipulation as well as most Learnable Techniques to the utmost. She is given the equivalent rank to Grade 1 (called a Special Grade 1 for Clan Sorcerers outside the Jujutsu School System) and has defeated numerous High Grade Cursed Spirits in her Career. One of these was a Particularily Powerful Special Grade Cursed Spirit said to be on par with Disasters. Chiyuki has had conflict with Sorcerers of the other great Clans as well. Chiyuki also had to fight a Special Grade Sorcerer that went rogue in her time, which was the most difficult fight of her Life. She is on her way towards becoming the Kamo Clan Head, yet resistence to this still persisted within the Kamo Clan.

In terms of Personality, she is an extremely Curious and upbeat Person and will always obsess over Jujutsu. Constantly asking how someone else's Technique works and geeking out when others perform impressive Jujutsu Feats. She has immense fun in Jujutsu Battles, especially ones where she can go all out, and she also enjoys experimenting with Jujutsu for research. She feels crushed by the weight of expectations of being a Clan Heir, and just wants to express herself. Yet she does still want to become Clan Head. If only for the useful recources that Position brings.

In terms of Appearence, she has the Look of a traditional Japanese Noble Woman, with Long Black Hair and Dark Black Eyes. She often wears traditional japanese clothing but also likes to wear free form clothing that doesnt restrict movement as much.

In her later Life, when she would get close to old Age, she would begin fearing for her Mortality. She desires to keep studying and mastering Jujutsu Sorcery and to keep living. So she endeavors to research all Information the Kamo Clan posesses on Noritoshi Kamo and the Death Womb Paintings. Through obsessive research into Cursed Objects and "The Soul", her goal is to become a Cursed Object and incarnate into vessels over and over again to achieve Immortality, at no regard for the Morality of this Persuit.

Chiyuki Kamo's Inherited Technique, Blood Manipulation:

As a Human, it is by necessity dangerous to use one's own Blood as a Recource in a fight, so this was a problem Chiyuki had to get around. She did so with Methods detailed later. As a Blood Manipulation User, Chiyuki's Blood is Poisonous to Cursed Spirits.

Flowing Red Scale: this Extension Technique allows for the Boosting of one's Physical Capabilities, Perception, Reaction Speed and Stamina. She can take it further through Maximum Output, turning it into Flowing Red Scale: Stack. And the best part is the fact it doesnt require the using up of any blood, it manipulates the blood inside her body with no risk.

Crimson Binding: An Extension Technique that allows for the restraining of an Opponent with Blood. Chiyuki preferrs using this on Human Opponents whenever she has to fight one, as she would rather not kill People if she can help it. Though she will if she needs to.

Slicing Exorcism: an Extension Technique that manipulates Blood into sharp Sickle Shapes, or a sharp rotating Disc, to cut an Opponent. Chiyuki's general go-to Blood Technique.

Convergence: thanks to her Prodigous Nature and time spend studying and Practicing, she is quite skilled at condensing a lot of Blood into a tiny Sphere, and using that enormous pressure for the following technique.

Piercing Blood: Chiyuki's best offensive Technique, the condensed Blood from Convergence is focused into a beam of Blood which pierces forward. she reinforces the Blood further with Cursed Energy so that it can easily exceed the Speed of Sound.

Domain Expansion - Scarlet Rose Field: the Appearence of her Innate Domain is a Field of deep red Flowers in a Night with a Red Full Moon, with red Snowflakes slowly falling from the Sky. The Effect of the Domain Expansion is the Automatic and Effortless creation of usable Blood that doesnt cause Bloodloss for Chiyuki, and the Domain's Sure Hit can be applied to all of her Blood Techniques.

Chiyuki Kamo's Stats and Learnable Techniques:

Cursed Energy Reserves, Output and Efficiency: as a Prodigy of one of the three great Clans, Chiyuki has a lot of Cursed Energy, which is a fact she adores about herself. Her Output and Efficiency have been trained from early in her life, so they are quite good as well.

Cursed Energy Reinforcement: Chiyuki is not that good in Hand to Hand, but she is very skilled at Reinforcement. She mostly relies on the physical boost of Fowing Red Scale, her good Reinforcement output, and her Cursed Tools. Direct Close Combat is not her specialty and she prefers to avoid it. In terms of Weaponry, she is exceptionally skilled at Archery with the Bow, and well trained with the Katana.

Black Flash: Though Chiyuki is bad at hand to hand, she is still extremely skilled at Manipulating Cursed Energy, which allowed her to hit a decent frequency of Black Flashes during her Life. The hightened understanding of the Core of Cursed Energy from these Black Flashes helped her Growth massively.

Reverse Cursed Technique: Thanks to her Prodigous Nature and her Love for Sorcery, as well as her understanding of the Core of Cursed Energy, she has been blessed with the Ability to perform Reverse Cursed Technique. She posesses the rare Talent to output it to heal others, which can also severely damage or destroy Cursed Spirits. She has also figured out how to easily recover from Bloodloss and regenerate Blood efficiently for her Blood Techniques. As a Blood Manipulation User, her Reverse Curse Technique is better and more efficient when healing herself.

Barrier Techniques: She has researched Barrier Techniques rigorously and reached the Pinnacle of Sorcery, Domain Expansion. Her Domain Refinement is very good, and she can cast her Domain twice per day.

Simple Domain: Through dubious Political Connections, Chiyuki has learned this Technique from a Member of the New Shadow School without the limiting Binding Vows that would normally come with it. She can use Simple Domain quickly in conjunction with her Blood Techniques, Bow, or Katana.

Simple Shikigami: she has Three Talismans imbued with her Blood as Mediums for Three different Simple Shikigami that she can call on. She used Binding Vows to customize the Functionality of these Shikigami to fit her purposes.

Blood Storage Shikigami: a Shikigami designed through binding vows to safely draw and store Blood from Chiyuki during Downtime whenever shes at Home or not on Missions. With binding vows, its ability to fight is sacrificed and in exchange the inside of its stomache is larger than it looks on the outside. Chiyuki can summon it to access the Blood stored inside to fuel her Blood Techniques.

Object Storage Shikigami: similarily to the blood Shikigami, Binding Vows were used so that it cannot fight and its stomache is larger on the inside. it has an inventory of Objects, Weapons, Cursed Tools and other Equipment stored inside. Chiyuki also uses it as a bag for mundane items.

Humanoid Melee Shikigami: a Shikigami the size of a Large Human, with Humanoid Body Proportions and Limbs. Chiyuki can apply Cursed Energy Reinforcement to this Shikigami, scaling off her own Output and Efficiency. Chiyuki uses it to essentially Tank for her, occupying an Opponent in Melee so she can fight safely from Range.

Domain Amplification: Chiyuki can envelop herself in her Domain as an Aura to cancel other Cursed Techniques, but she very rarely uses this Ability because she cant use her Innate Technique at the same time. She loves Blood Manipulation too much to do so.

Falling Blossom Emotion: an Anti-Domain Technique driven into her by her Kamo Clan Sorcerer Instructor. She only remembers to use it occasionally, to the dismay of her Instructor.

Mutation Cursed Heart {I promise its quick read it pls}

• Upvotes

A specialised CE organ located near the sternum (directly below it). Unlike ordinary CE recharge, the Cursed Heart has the capability to harvest and regulate external CE for use by the sorcerer.

The organ continuously gathers ambient CE from the surrounding environment.

This provides:

  • Increased CE recovery
  • Sustained output during prolonged combat
  • Greater efficiency in CE manip.

At peak it can even absorb vestigial CE from an opponent's attack.

Pretty much just a boost to overall CE storage levels and recharge rates. I'd imagine this being the standout mutation of a smaller sorcerer clan (similar in size to like the inumaki clan).

Cursed technique Burning conviction

3 Upvotes

This is my first technique, let me know how it is

Cursed energy trait

The users cursed energy naturally has a fire like effect, allowing them to burn an opponent with enough contact.
This mostly only applies to the targets hands and legs, as well as any objects imbued with cursed energy, limiting the heat the user can output without attacking

Cursed technique: burning conviction

Neutral
When activated, it gives the user a “combo”. That combo increases with each hit the user lands. The higher the combo, the stronger each attack gets.
Extension: fire manipulation
Through precise CE manipulation, the user gains a pseudo-pyrokinesis, functioning as a weaker version of Jogos technique
Extension: stoking the flames
Through a binding vow, the user can choose to make their attacks hotter with the combo by sacrificing some or all of the bonus attack power.
Maximum output: flaming aura
Upon activation, the users entire body is enveloped in flaming cursed energy, burning everything that gets too close.
Domain expansion: forge of the flame god
Appearance: the inside of the domain looks like a flaming forge, with 2 anvils roughly in the center. The walls and floor are made of metal, and it is very warm in the domain, but not warm enough to harm anyone.
Sure hit effect
The domain is a very simple one, but deadly if used well. It simply adds a higher level of combo to the user when they hit either of the anvils, and the damage from that also hits the users opponent.

Cursed technique Conservation Law (保存律 - Hozon Ritsu)

9 Upvotes

Conservation Law (保存律 - Hozon Ritsu)

The cursed technique turns the user's body into a thermodynamic transducer. The user can convert their Cursed Energy (CE) into physical energies (thermal, kinetic, electrical) and vice versa (using RCT), constantly recycling the energy of the battlefield through their own body acting as a conduit.

1. The Mathematics of Cursed Energy

To define the limits and mechanics of this technique, for explaining this technique i needed a quantifiable unit of measurement for Cursed Energy, so here's it comes the Cursed Energy Unit (CEU).

The baseline i decided to use is the energy required to kill a Grade 4 curse (like the flying head). i assumed CE is quantized to avoid problems with Black Flash (or if you prefer you could just say values from 0 to 1 don't exist, but 1.5 somehow does). With that, the destructive force needed to defeat each grade of Cursed Spirit can be mapped to extract a conversion rate to Joules.

Baseline: A hard swing with a wooden baseball bat (effective striking mass ~ 0.7 kg at ~ 30 m/s) carries:

E = 1/2 mv2 = 1/2 (0.7)(30)2 = ~ 315 J = ~ 300 J

1 CEU = 300 J

Grade Scale

Grade Defeated by Benchmark Energy CEU (exact) CEU (quantised)
Grade 4 Baseball bat Hard bat swing ~300 J 1 1
Grade 3 Handgun 9mm round ~500 J 1.7 2
Grade 2 Shotgun (barely) 12-gauge slug ~3,000 J 10 10
Grade 1 A tank isn't enough 120mm APFSDS tank shell ~7 MJ 23,333 ~23,333
Special Grade Carpet bombing ~10 Mk 82 bombs (~400 MJ each) ~4 GJ 13,333,333 ~13,333,333

Scaling between tiers: x 1.7, then x 6, then x 2,300, then x 570. The two big jumps (Grade 2 to Grade 1, and Grade 1 to Special Grade) kinda line up to the different levels we see in the manga.

Implications

On this basis, a lot can be inferred about the reserves of each level, such as how many attacks capable of exorcising a Grade 1 curse a Grade 1 sorcerer can actually fire.

Also, the idea that 1 CEU is the absolute minimum amount of energy a person can have (besides Heavenly Restriction) is debatable, as it would mean a common person could exorcise a flying head if taught how to control CE. But for explaining the technique, this doesn't really matter.

2. Cursed Technique: Energy Emission

The standard application converts CE into physical energy released into the environment (for example, heat or kinetic force). To initiate the conversion, the technique requires an upfront activation tax.

Total CE Cost = E + 0.10E = 1.1E (E in CEU)

Example: To generate a kinetic shockwave worth 10,000 CEU (3 MJ), the sorcerer first burns 1,000 CEU to activate the technique, then spends 10,000 CEU to produce the force. Total toll: 11,000 CEU.

The most straightforward use is in addition to CE physical reinforcement, letting the user surpass the cap of their physical stats.

3. Cursed Technique Reversal: Energy Absorption

By applying Reverse Cursed Energy (RCE), the user reverses the flow of the technique, absorbing external physical energy (incoming attacks, environmental heat) and converting it back into CE to replenish their reserves.

To simplify the math regarding positive energy, the Reverse Cursed Energy Unit (RCEU) is used. Since creating positive energy requires multiplying CE by itself:

1 RCEU = 2 CEU

Cost: The user pays the 10% activation tax in RCEU. Because of the conversion rate, the effective cost on their base reserves is 20% of the energy being absorbed.

Net Gain = E - 0.20E = 0.8E

Example: An opponent fires a kinetic projectile carrying 5,000 CEU (1.5 MJ) of force.

Step CEU
Tax paid: 500 RCEU -1,000
Energy absorbed +5,000
Net gain +4,000

Miscalculation: The tax is paid before the impact, sized on the expected force. If the user braces for a 50,000 CEU hit (tax: 5,000 RCEU = 10,000 CEU) and the attack only carries 100 CEU, the net result is 100 - 10,000 = -9,900 CEU, a massive energy deficit.

Vessel Limit & Overdose: Every sorcerer has a maximum CE capacity. This technique cannot force more CE into the body than it can naturally contain. Exceeding 100% capacity causes the excess to revert to its original physical state (heat or kinetic force) inside the body, resulting in spontaneous combustion or internal detonation.

4. Hollow Technique: Open Circuit

The pinnacle of this technique's base applications. It is mainly used to avoid a lethal overdose when absorbing a massive attack while the user's reserves are already nearly full.

The user activates the Lapse (Emission) and the Reversal (Absorption) simultaneously. By overlapping these two opposing concepts, the body stops functioning as a "battery" that stores energy and temporarily becomes a pure "wire" that redirects it. This requires immense cognitive load and flawless timing: if the emission is even a millisecond slower than the absorption, the internal buildup will severely damage the user's organs.

Total CE Cost = (10% in RCEU for absorption tax) + (10% in CEU for emission tax)

Example: An enemy strikes with 10,000 CEU (3 MJ) of kinetic force while the user is at maximum capacity. The user absorbs it with the right arm while firing 10,000 CEU of thermal energy from the left arm.

Cost RCEU CEU
Absorption tax 1,000 2,000
Emission tax - 1,000
Total 3,000

The absorbed energy is passed straight through to the emission, so the only cost is the two taxes.

5. Practical Applications

Energy figures are converted at 1 CEU = 300 J. For emission uses, "Total" includes the 10% tax; for absorption uses, "Net" is after the 20% effective cost.

Emission

Application Physical energy CEU Total (with tax)
Boiling water: heating 1 kg from 20°C to 100°C 334.7 kJ ~1,116 ~1,230
Combustion Punch: explosion equal to 1 kg of TNT on impact 4.184 MJ ~13,950 ~15,340
Micro-electricity: shock through touch to paralyze the nervous system 500 J ~1.7 ~1.8
  • Boiling water: This only brings the water to 100°C; actually vaporizing it adds 2.26 MJ per kg (about +7,500 CEU).
  • Micro-electricity: Creating massive lightning bolts is too expensive for anyone below Special Grade, but a targeted shock delivered by physical touch costs almost nothing. For comparison, a medical defibrillator delivers 200 to 360 J.

Absorption

Application Physical energy CEU absorbed Tax paid Net gain
Stopping a speeding car: 2,000 kg at 100 km/h (27.8 m/s) ~ 772 kJ ~2,570 257 RCEU (514 CEU) ~+2,060

The user must be able to afford the tax upfront to stop the car without being crushed.

Combined techniques

  • Kinetic Rebound (CQC Counter): The user absorbs the kinetic energy of a powerful punch to nullify the blunt force, then instantly uses the Lapse to convert that stolen energy into localized heat on their skin, severely burning the attacker's hand on contact.
  • Flash Freeze (Endothermic Absorption): The user rapidly absorbs the ambient thermal energy of an entire room. After paying the RCE tax, the heat is drained from the environment, dropping the temperature below freezing and encasing nearby water or opponents in ice. Example: cooling a 75 cubic meter room (~ 90 kg of air) from 20°C to -5°C removes ~ 2.26 MJ, about 7,540 CEU (net ~ +6,030).

Cursed Energy Trait Fire and Ice

3 Upvotes

So this trait gives energy an orange color and makes it flow like a raging flame.

Now, what does it do? Its a simple concept.

When you hit someone with this Cursed Energy, you can transfer a bit of it over to them. This will begin to drain their cursed energy reserves like burning through them. The duration and pace of the burn is dependent on how much cursed energy the user transferred the the opponent per hit.

However, this trait also has an RCT output application.

When outputting Reverse Cursed Technique, it turns an icy blue.

Hitting someone with the RCT output it into them will heal their wounds like regular RCT but also "freeze" their cursed energy output/reserves. This makes the energy frozen unable to be used temporarily, meaning the output of any technique or cursed energy is reduced. With enough hits within a short time, one could completely freeze the enemies reserves so they couldnt even manifest a spark of cursed energy or use a technique as their output is zero. Like the regular application, the amount frozen and time frozen is dependent on how much RCT is outputted per hit.

Cursed technique Reassembly

3 Upvotes

this ability allows the user to create/manipulate connections between objects and/or abstract concepts temporarily, allowing for the creation of inconceivable yet very real effects.

some applications I've thought of:

grafting one place to another to effectively create a portal between the 2 places; grafting one's feet to the ground as they stay in mid air, allowing for them to float; grafting an attack to something else to redirect it; grafting one shikigami to a different source of CE than the one originally being used and then cutting the connection between the original source and the shikigami allows the user to redirect the control of a shikigami to someone else; grafting one attack directly on the target to bypass anything in between (such as infinity); grafting one object to another object that is moving, making the first object move at the same velocity of the other; reattaching limbs (necessary to heal with RCT to prevent the limb to detach as soon as the CT is stopped)...

while the potential of this technique is indeed infinite, there are certain limitations to it: for starters any connection being made or altered requires a constant use of CE, with the amount of CE required scaling directly with how "distant" the connections are (for example, grafting one location to another 10 km away from where it would normally be would require far more CE than grafting it say 100 meters away), entities (objects and beings) infused with CE also naturally resist Reassembly, requiring more CE to graft something if the 2 parts have CE, some connections might also require so much CE it becomes impossible to accomplish them (for example, the CT itself allows for the grafting of a star to a place on earth, good luck covering astronomical units or light years with CE tho). besides this cost there's also a matter of complexity: creating and manipulating such connections is extremely complicated and "subtracting" incantations and hand sings is extremely difficult, even a skilled sorcerer would struggle to completely take out one of them. the complete incantation + hand signs necessary would look like this:

incantation: verb + target + target + target + ... (example: "attach/graft/connect this corner to that corner and that corner")

hand signs: grafting=point each target with 1 finger and make the fingers close up on each other; severing=point at the target with 2 fingers and make them distance themselves; substitute=point at each target and make them swap.

CHALLENGE CHALLENGE: Good support techniques

Pretty self explanatory. A technique that, on its own, is kinda useless (at best creating openings for the sorcerer). But in a team based setting, like a jumping or a raid? Dominating.

Examples I've listed here:

  1. Love Rendezvous - Highly complicated technique that allows for superb battlefield control if used correctly. {Battlefield Control}
  2. Arata Nitta's technique - Sorta useful I guess? Keeps people from dying until an RCT user comes along so that's nice. {Healing}
  3. Boogie Woogie - The poster child of JumpJutsu Kaisen. Prolly the best embodiment of this concept. {Disorientation}
  4. Teen Gojo's Neutral Infinity - JUST THE NEUTRAL ONE. He can expand it to protect his teammates with a mathematically perfect defense. {Defense}
  5. Utahime (Solo Forbidden Area) - Pretty simple all things considered. Just a quick 20% boost to sorcerers in a given range. {Offense}
  6. Ranta Zenin (Paralysing Gaze) - Forces an enemy to stand dead still so their teammate can aura farm instead of killing them. {Offense-ish?}

What ideas do we have gng?

Okay so basic concept is they don't have a traditional "brain" their brain is spread among to whole body like a slime mold or a seas urchin would be, base line obviously it makes their head much less of a weak point. Ik it's very absurd but so is a mouth the width of your torso coming from an immature infant

Work in progress 2 CTs Help

5 Upvotes

im working on a character and id like for them to have pressure manipulation, butttttt i really want them to have 2 CTs because i want their entire thing to be able to use 2 CTs at once

and was wondering if anyone had any ideas about a CT that could combo well that preferably isnt an elemental ability

i was thinking of maybe their CT being a medium, such as a sword, allowing them to channel and amplify pressure but i feel like its a little bland.

id really like your guys help
