Satsujinki

Among all S-rank Akudama, the Satsujinki stands out as the most unpredictable force of destruction. Beneath a disarmingly gentle smile and impeccably polite manners lies a mind consumed by a morbid fixation on the color red and the sight of blood—a fixation that transforms him into a merciless killer the moment violence begins. When a chance encounter led him to believe an ordinary civilian had saved him from execution, an obsessive bond was forged, driving him to protect that person with terrifying intensity. His presence within the group is a constant, volatile wildcard.
