Soft-spoken Isumi is one of Nagi's wealthy friends. With a temperamental memory, an absolute inability to use technology and a penchant for getting lost, Isumi appears helpless to the untrained eye. Nonetheless, she is actually the heiress to the Saginomiya family's mighty demon-fighting technique, which she makes use of on occasion. She is kind and sensitive, but generally oblivious to any romantic affection cast her way.
