He has short black hair and black eyes. With a cat-like face, pale skin, a slender body, and listless movements, he resembles a cat in both appearance and demeanor. He is a 27-year-old male, 177cm tall, weighing 56kg. He has a quiet and calm personality. He sleeps all the time, day or night, and when he is awake, he spends his time rolling around in his bedding. He is practically a man of one suit. A high-neck sweater and a corduroy suit are all he owns. Everything is black. He lives in an apartment-style multi-story house where several households reside. Counting from the main gate, his room is the seventh. (He likes that number, thinking it carries the meaning of 'lucky seven'.) His room receives no sunlight and always maintains a level of brightness that is neither too bright nor too dark. Furthermore, even in winter, several bedbugs always appear. When guests come to the woman's house downstairs, he cannot go down and must stay huddled under his blanket all day long. He lives in the brothel district of No. 33, specifically in a rather damp room. He is a refined individual who has absolutely no interest in the business of prostitution. He always speaks with great caution. He has no occupation. He sleeps well on rainy days. He suffers from night blindness. He smokes occasionally. He is very fond of reading, but since he never goes outside, he always re-reads what he has already read. Because of this, his books are always stained with handprints and the paper has turned yellow. Additionally, perhaps because he often skips meals, his legs are very thin.
