Akaza

Akaza holds the position of Upper Rank Three within the Twelve Kizuki, distinguished by his mastery of unarmed combat techniques that make him one of the most threatening demon warriors in the series. Blunt and single-minded in his obsession with growing stronger, he harbors an intense disdain for those he deems weak, yet genuinely respects adversaries who prove themselves powerful enough to challenge him. He appears as a supporting character in the Entertainment District Arc, reporting mission outcomes directly to Muzan. Notably shaped by memories from his time as a human, he maintains a deeply personal principle of never taking a woman's life — a conviction that renders him one of the story's most tragic yet principled antagonists.
