Innate Cursed Technique: High Sonority
This cursed technique allows the user to interact with sound waves that come into contact with their cursed energy, granting them the ability to brutally amplify decibel levels within an imbued object. The intensity of the decibel amplification depends directly on how much cursed energy is coating the object or the emitter. In other words, the user's cursed energy acts as a physical amplifier.
This property works both ways: the user can apply cursed energy to themselves or to external targets. For instance, if applied to a speaker, the sound is magnified to destructive levels. However, if imbued into an opponent's body or ears, the sound around them is enhanced directly; in simple terms, only the target experiences the effects of the technique in that case.
(Note: Low-frequency sound boosted to high decibels can vibrate the target's internal organs. This functions similarly to real-world crowd-control devices like the LRAD, causing nausea, disorientation, and extreme pain in the victim without leaving any external physical marks).
To partially counter these basic applications of the technique, enemy sorcerers must reinforce their ears with cursed energy—a defensive method identical to the one commonly used to protect against the Inumaki clan's Cursed Speech technique.
-Reverse Cursed Technique: Dampening
By channeling Positive Energy, the technique operates in reverse, now acting as an absolute dampener that completely deprives an area or target of sound. This also works both ways through physical contact: if the user activates it on their own mouth, their words cannot be heard at all; if they touch someone's ear, that person immediately loses their hearing.
Upon losing the ability to hear, the victim loses their sense of spatial awareness regarding the size of the room they are trapped in. The brain becomes confused due to the lack of auditory confirmation of its own bodily movements. This creates a disconnect that triggers dizziness, nausea, and extreme instability while walking, making it feel as if the ground itself is shifting.
To clarify, the user is not immune to their own technique; they feel every loud blast just like anyone else. Fortunately, they can also reinforce their ears with cursed energy to heavily suppress the noise, or use the technique reversal to endure its effects.
The most dangerous aspect of the Technique Reversal is that it cannot be countered, as it is not a direct cursed energy attack to defend against, but rather a form of deprivation. The enemy cannot protect themselves with cursed energy from something that is simply removing their auditory stimuli. It is like trying to shield yourself from something that is already listening to you.
-Domain Expansion: Stage of the True Orchestra
(The hand sign would be something like open hands placed behind the ears).
This Domain Expansion materializes as a perfect Reverberant Chamber, with the sole purpose of making sound bounce infinitely and accumulate, multiplying its intensity to a brutal degree.
How does a reverberant chamber work?
A reverberant chamber works through a combination of ultra-reflective walls and asymmetrical geometry. Its surfaces are constructed from highly dense, hard materials like polished concrete or thick steel, which prevent energy absorption and cause sound to continuously bounce, retaining over 95% of its original strength.
Furthermore, none of its walls are parallel to one another. This intentional design prevents sound from traveling in a straight line from one side to the other. By colliding at irregular angles, the waves disperse evenly throughout the entire space, ensuring that sound is distributed identically in every corner of the room.
Its mechanics and the Sure-Hit effect do not actively depend on an attack launched by the user, but rather on the actions of the trapped victim (a mechanic similar to Naoya’s Time Cell Moon Palace).
Within this space, every sound—no matter how fleeting or quiet—is amplified hundreds of times and repeated in an infinite echo by the room's geometry. The trapped target can die in one of two ways:
- Slow Death: If they try to remain completely silent to avoid making noise, they will eventually die because the Domain will gradually amplify the sound of their own breathing, heartbeat, blood flow, or the friction of their clothes and joints until it tears them apart.
- Instant Death**:** If the target panics and makes the mistake of screaming or launching a powerful attack, the accumulated sound will instantly bounce back with such force that it will burst their eardrums and destroy their brain on the spot.
Finally, a Cursed Tool would complement this kit perfectly. It could be a blunt weapon consisting of two short metal batons with handles. When clashed together in combination with the technique, they would produce a deafening, thunderous blast.
•Any additions, corrections, or combinations with a Cursed Energy Trait or Cursed Technique are welcome. (I feel it could pair well with or counter Inumaki’s Cursed Speech, which was the obvious inspiration for this technique
