Toranosuke's older sister Leona used to be part of the Supernatural Studies Club, but she stopped going to school after finding out the seventh witch's name.

She's developed a pretty unsettling habit of throwing scissors at anyone who dares to intrude on her space—so yeah, don't bother her uninvited.
