Hana Oshiroi is an easily excitable girl who joins the Half Priced Food Lovers Club. Her hobby is writing yaoi erotic novels, having its characters inspired on other wolves. Not a fighter type at all, Hana usually resorts to sneaking past the other wolves while they are fighting to grab a bento for herself, which ironically, works most of the time. People used to bully her and get mad if she even touched them, saying that she has germs and will infect them, until she began to frantically apologize to anyone she touches and try to clean them up after the "contamination". Since meeting Sen and Yō, that behaviour has gradually changed and eventually, it no longer occurred.
