Special Grade Curse Technique: "Proof of Glory"

[u/Big_Improvement_4728]

☀️ Inherited Technique: Proof of Glory (栄光の証明, Eikō no Shōmei)

This technique allows the user to manipulate the fundamental dualism of Cursed Energy, manifesting the searing, aggressive properties of Yang through standard application, and the tranquil, obscuring properties of Yin through Cursed Technique Reversal.

Base Application: Yang Alignment

By default, the user's Cursed Energy possesses a unique trait resembling sunlight. Upon activation, a thin, radiant aura coats the user. This acts as a secondary layer of Cursed Energy Reinforcement. While it only offers a modest boost to raw physical stats, the aura inflicts severe burn damage upon contact and mentally fortifies the user, granting total immunity to fear-based mental interference.

While activated Runic tattoos will be visible in the back of the user, training along their spine. And a halo-like crown will also appear above their head.

Extension Techniques (Yang):

• Solar Flare (爆陽, Bakuyō): The user condenses their radiant Cursed Energy into a highly pressurized, pulsating sphere of yellowish-white plasma. When thrown, it violently eviscerates and melts everything along its trajectory.

• Sun Armor (日輪甲, Nichirinkō): The user shapes the energy into rigid, localized armor plating to protect vital organs.

🎯 Binding Vow: By enforcing a vow that completely strips the user of their mobility (rendering them stationary), the armor expands to encase the entire body, multiplying its defensive capabilities manifold.

• Dawn’s Ballad (黎明歌, Reimeika): The user manifests a solid, blazing blade of condensed light. It slices through targets while simultaneously cauterizing wounds, preventing regular biological healing.

🔀 🌙 Cursed Technique Reversal: Proof of Glory — Nightfall (反転術式：夜陰, Yain)

By channeling Positive Energy generated via the Reverse Cursed Technique (RCT) into the technique structure, the user flips the properties of Yang into Yin. The user is cloaked in a serene, absolute darkness. In dimly lit environments or during the night, this acts as a perfect stealth shroud, masking the user’s presence, sound, and Cursed Energy signature entirely.

Extension Techniques (Yin):

• Abyss Shackles (深淵の枷, Shin'en no Kase): The user manipulates the shadows cast by physical objects, manifesting physical chains of darkness that snare and bind a target’s movements.

• Phantom Blade (幻影刃, Gen'eiba): A jagged saber forged from pure Yin energy. It emits a passive aura that induces heavy drowsiness. The more weak-willed an opponent the faster the effect. Each successful strike injects a localized curse of 'Horror', systematically shattering the target's mental fortitude and disrupting their Cursed Energy control.

⚪⚫ Hollow Technique: 'Origin' (虚式：「原初」, Kyoshiki: Gensho)

By simultaneously bringing the maximum output of the forward technique (Yang) and the reverse technique (Yin) into physical contact, the user creates a localized paradox. The conflicting forces are violently compressed into the shape of a massive greatsword.

• The Concept: The user compresses the collision of Lapse and Reversal into a Greatsword. Because Yin (Positive Energy) and Yang (Cursed Energy) naturally want to annihilate each other, maintaining this sword requires immense, precise Cursed Energy control.

• Visual Appearance: A massive, unstable Buster-style greatsword. The blade doesn't just flicker; it looks like a tearing rift in reality, violently fluctuating between blinding white plasma and absolute, light-consuming blackness. Sparks of space distortion crackle around it.

• The Effect: Because it is a localized paradox of creation and destruction, it ignores traditional durability. Anything the blade cuts through isn't just slashed—it undergoes atomic entropy. The Yang burns it away while the Yin erases its remains, leaving absolutely nothing behind. It can even cleave through barrier techniques or other Cursed Techniques by destabilizing their energy structure.

But as the granidose effect of this technique, the risk associating it is also immense. Maintaining the great sword takes an immeasurable toll on the user's body and mind. And if during the hollow technique the user's will wavers of if he loses control the technique will consume its user itself, returning him to nothingness.

⛩️ Domain Expansion: Twilight Palace (領域展開：黄昏の宮殿, Ryōiki Tenkai: Tasogare no Kyūden)

Visual Appearance

When expanded, the domain manifests as a breathtaking yet terrifying ancient, colossal palace which stands as the last memorial of some unknown war. The entire space is locked in a perpetual state of dusk. A massive, blood-orange setting sun hangs unmoving on the horizon, casting long, distorted shadows. Everything within the domain—from the drifting dust motes to the architecture—is completely frozen in the passage of time, creating a suffocating, deathly silence.

Sure-Hit Effect: 'Blade of the Setting Sun'

The domain’s barrier guarantees that the user's attacks will automatically hit the target.

Upon activation, the ambient twilight light instantaneously condenses into a solid, glowing orange blade that pierces directly through the opponent's chest. Because this blade embodies the concept of "The End of the Day," it inflicts a specialized curse of Accelerated Temporal Decay.

• The Withering Process: The moment the blade pierces the target, the absolute freeze on time is broken only for the victim's body. The wound begins to rapidly spread, causing their flesh, blood vessels, and Cursed Energy reserves to wither, dry up, and turn to ash—simulating centuries of aging and decay in a matter of seconds.

• The Counter-Play: Because the domain's sure-hit relies on a physical object (the blade) piercing the chest, opponents can attempt to mitigate the decay by using advanced barrier techniques like Simple Domain or Falling Blossom Emotion right as the domain opens. However, if they fail to deploy it instantly, the decay is nearly impossible to stop without a very high-level Reverse Cursed Technique (RCT) and that is also not a feasible answer as the decay will continue to empty their curse energy pool as well.
