He sports a green jacket with a limited edition OTM Girls patch, which he was able to acquire as a long-time fan of the band. He was once a dedicated fan of the OTM Girls. Nevertheless, his inability to accept changes has morphed him into a deranged person, going far lengths to assault Retsuko, whom he openly despises and vents at for changing OTM Girls. He is first seen as an OTM Girls superfan who stalks the girls and Retsuko, posting their pictures online on a fake OTM Girls social media profile. It is later revealed that, in addition to being an obsessive stalker, he verbally and physically attacks Retsuko. His assault with a box cutter was stopped by Haida, and he is currently in jail for the attempted attack.
