Matsuda, Shinobu

松田忍

Initially, Shinobu appears as one of Satsuki's classmates. She appears to possess knowledge of black magic, which she teaches to the other girls in the class to help them fulfill their wishes. However, these spells are actually a trap designed to have the girls' souls stolen by darkness, and Shinobu is, in truth, the Avatar of an evil deity named Yamime. Eventually, Satsuki discovers that Shinobu was formerly her mother's classmate who had vanished under mysterious circumstances. It is possible that upon her "second death," she was permanently consumed by Yamime. She reappears in the 20th episode.
