Recorder for the 3rd-ranked House, Kosagiic. He was born into a warm family, but when he was three, his father's affair was discovered, leading to his parents' divorce and him being taken into a facility. At the facility, no one looked at him; even when he spoke, he was ignored, as if he never existed from the start. This trauma made him stop talking much. He never smiled while at the facility. At 15, he left the facility to live independently. He lived alone and became obsessed with listening to hip-hop music. At 16, he moved to TOKYO CITY. After moving, he looked for a job where he wouldn't be left alone and happened upon the Nest. He passed the exam and became a Recorder for Kosagiic. At first, he was terrified of being left alone again. However, the detective Haru treated him like an errand boy. Surprisingly, he was happy to be treated that way by Haru and accepted it.

Recorder for the 3rd-ranked House, Kosagiic. From the time he was born, his parents fought constantly in the middle of the night, screaming and hitting each other over child-rearing issues. Terrified, he would always hide in an old warehouse outside the house. Since then, he has hated loud noises and voices. When he was five, his parents divorced, and he went with his mother. His mother then developed depression, and he could do nothing but watch her suffer. Once he started school, he was bullied, called "gross," and told "don't come near me." Despite the bullying, he forced himself to keep a smile on his face. After graduating middle school, he became independent and lived alone. Since then, he lost track of what his mother is doing or where she is. After living alone, he started getting headaches when hearing loud noises or voices, and excessively loud sounds would trigger hyperventilation. However, he loves music. At 15, he composed his first song, "We Who Find Life Hard," which became popular. At 16, he moved to TOKYO CITY. That same year, he was caught up in a murder case. He was saved by the Nest during this incident, which sparked his interest in them. After passing the Nest exam, he became a Recorder for Kosagiic. Knowing that Haru and Hayato are reliable, kind people, he grew to love them both. Because of them, he has come to love his life now. He has shared his past with the other members.
