As a demon, Akaza was a muscular young man with skin so fair that appears bright green-tinged white, decorated by a pattern of thick blue lines, which resemble the criminal tattoos he had as a human. The lines on his face curved through each of his eyes from below his ears to over his temples, another blue line running from the center of his hairline to the bridge of his nose, with two more lines running around his neck, three others branching off the lower one to his torso.
