Shizuru Shirosaki

Оригінальне ім’я: 城崎志弦

Usa's somewhat perverted author roommate. Known for being a masochist, he specializes in bondage and can tie complex knots that are difficult to undo. He is good at crafting which he usually employs to while away boredom or make Mayumi feel better. When outside, he is usually marched off to the police station for being a suspicious character. Caught sticking his head through a hole in a fence that surrounded a grade school, he is the third resident that Usa meets.
