He has dark purple hair and green eyes. His gaze is vacant, with dilated pupils that lack a spark of light. He is depicted with a reliable presence and a muscular build. Contrary to the impression that he might be quite large, he is surprisingly not tall. He is actually short. He wears flamboyant Japanese clothing that looks closer to women's attire than men's. In the manga, it features floral patterns, while in the anime, it was changed to butterfly decorations. Currently, even in the original manga's illustrations, the anime design is followed. The overall concept in the anime is frequently linked with butterflies. Notably, he wears a fundoshi. He is a man of peculiar appearance, carrying a kiseru pipe with his left eye blinded by a past wound and covered in bandages. In the 'two years later' arc covering the final stages of the original work, he goes without the bandages, revealing his blind eye.
