An eighteen year old boy named Tetsuo betrayed his own cousin and was sold at auction to settle a debt owed by Tetsuo. Kanou bought him for 1.2 million yen, and the boy had to pay off the debt by having sex with Kanou for 500,000 yen each time. Despite losing both of his parents at a young age, he struggled with loneliness during his childhood. He is gentle and naive, making it difficult for him to express himself or socialize with others. However, Kanou has forced himself into the boy's life. The boy also tends to get in trouble because he doesn't realize that men are attracted to him when he's around. In the manga, he is trying to change his personality and become more outgoing and sociable. With Kanou's permission, he currently works part-time as a kitchen helper at Someya's bar. An interview with him reveals that his motto is "little by little" and that he washes his left arm first when bathing.
