"Art of Flesh Desecration" (肉穢の術, Nikuwae no Jutsu)
This Blood Demon Art revolves around violating the integrity of flesh and identity, inflicting existential and physical torment.
1. "Marionette Maw" (糸呑み - Itonomi)
He extends black tendrils of rotting muscle fibers from his back and chest cavity.
When these tendrils latch onto flesh, he gains partial control over the victim's body — like a grotesque puppet master.
The victim remains fully conscious, unable to resist their body betraying them.
Maximum of two puppets at once.
2. "Flesh Mosaic" (肉の寄せ絵 - Niku no Yose-e)
He can combine multiple corpses or body parts into an unholy amalgamation — twitching, sobbing creatures made of victims.
These creations don't fight well, but they whisper the last words of those used to create them, breaking the will of onlookers.
Works best on weaker slayers or civilians who see comrades used this way.
3. "Suture Field" (縫界 - Hōkai)
Can deploy a trap that spreads invisible threads over a wide area.
If someone steps on or through them, they get "stitched" to the environment — walls, floor, even other allies.
Targets become immobilized, their limbs pulled unnaturally while still alive.
Can only trap three at a time, and he must manually set it in advance — not during intense combat.
4. "The Maw Within" (腹の口 - Hara no Kuchi)
The gaping hole in his chest opens into a mouth that devours flesh, but also spits it back out in warped forms.
Anything he eats — weapons, flesh, techniques — returns as a grotesque mimicry. E.g.:
A slayer's arm becomes a bloated claw attacking allies.
A devoured sword gets reformed as a twisting, mangled metal snake.
These twisted copies are imperfect and fragile, but deeply unsettling to see.
