Ayano Aishi is a student at Akademi High School. Since early childhood, Ayano has suffered from an inexplicable, incurable condition. In short, this condition leaves her with a perpetual sense of being empty, hollow, and incomplete. This changed when she met Taro Yamada (Senpai), and became lovesick for him, determined to have his love and eliminate any love rivals.  Unless Taro is around, Ayano is generally very emotionless, uncaring, and speaks with a deadpan expression unless provoked.
