Kasumi Izumo is a student in Precept's Peak Academy and a participant in the killing game located there. Kasumi is a dangerous girl with, as she'll gladly yell at you about, REAL spiritual powers. She is known to be a very excessive person who doesn't care about other people's feelings most of the time. She cusses frequently when she gets upset and annoyed. She even mocks others and threatens to curse them with her skills when triggered.
