He takes baths occasionally, but still smells. An introvert who doesn't fit in with those around him. His voice is small, and he is disliked for being timid and fidgety. Because Miyu and Yayoi spoke to him kindly, he developed romantic feelings for them. He likes Yayoi, but lacks the courage to talk to her, let alone confess. However, he mistakenly believes she is his girlfriend. He hates Guest and Yoshito for being close to Miyu and Yayoi. However, he cannot act tough and is unable to even speak to them. Nevertheless, he occasionally acts like he's the boyfriend. Even if he gets angry, he can't do anything and doesn't take action. He has enough common sense not to commit crimes like violence, stalking, or voyeurism. He has no connections to gangs or the Yakuza.
