“A boy who eats demons to fight them, with no Breathing Style to call his own — a lonely war for his brother's acknowledgment.”
Eating part of a demon temporarily grants his body that demon's abilities and regeneration. A unique tactic born from having no Breathing Style.
A custom shotgun loaded with Scarlet Ore ammunition. Non-standard armament — a gun instead of a blade.
Consuming large amounts of high-tier demon cells can trigger a temporary near-demonification — extreme risk, extreme output.
A wall-builder. Behind his rough, standoffish exterior is a desperate need to be recognized by his older brother. He feels inferior — no Breathing Style, an aberrant constitution — but that self-awareness drives him toward more dangerous choices, not retreat. The harder Sanemi pushes him away, the deeper he commits.
