Akaza was a very muscular young man of average height with skin so fair, it appears bright green-tinged white, decorated by a pattern of thick blue lines, which resemble the criminal tattoos he had as a human. Akaza is a headstrong, stubborn and battle-crazed Social Darwinist who enjoys fighting, especially against strong Demon Slayers. Akaza looked down on anybody he deemed weak, so much so that his skin would crawl at the sight of them. Sees training as more important.
