Yaotome Itsuki

Lead heroine and childhood friend of Yuuichi.

At heart, Itsuki is a strong and determined girl. For the most part, her classmates are intimidated by her quick wit and notable intellect (resulting in keeping their distance from her). Because of this, she has grown used to doing things her way.

Though she will never openly admit it, she feels good when leading and protecting others. In fact, her sense of responsibility for others is what caused her to leave the school's computer club (where she was concidered a master hacker) and start the Occult Study Group.
