Hisui Tsurumi

Hisui Tsurumi is the daughter of the prestigious Tsurumi Group, and her true identity is that of a kappa. Having grown up in an environment surrounded predominantly by women, she developed a deeply introverted personality along with a strong fear of men. She participates in the Supernatural Research Club and spends her leisure time reading. Despite coming from an exceptionally affluent background, she consistently appears timid and reserved in front of others—a striking contrast that defines her unique character.
