When she was young, there was a craze going around about children with psychic capabilities, she was one of these people and had actual psychic abilities. However, when she was still young, she was interviewed to demonstrate her psychic abilities, however she was stressed and used a trick she learnt from a fellow psychic and was caught in the act, because of this she grew a bitter resentment and protected her pupil Chiaki Kasai from the other students harassment. She is the main reason that there is a curse at the school.
