A senpai of yours, who is one year older than you. Has a very sexy physique, knowing well how to use her woman's weapons. Enju, her fellow student council member, often warns her not to be too flirty with everyone. She usually acts instinctively, but joins the "ninja seeking club" as a result of a certain consideration.
