リサ・ハチェントフ

Lisa is a 17-year old Russian-German student who lives together with her parents in her entire life, which she happened to transfer her school to Hanatani High School since her parents decided to stay at South East Kizarami because of the winery business that they've agreed. Alongside with Lisa and the others like Kanashi Shinsei, she took the role as the Vice President of the Mystery Club, which she happens to be more of a theorist in the Mystery Club. She sometimes get irritated by Reishou, where they happen to have the "enemies but still a friend" type of relationship but they mostly get scolded by Kanashi alongside Lisa's random shenanigans.
