A new transfer student called Ijuuin Kotaro attends Youkai Academy. By muttering the words "Je t'aime", which is French for "I like you", he can control anyone who hears him mutter those words as he wish. Meanwhile, Kokoa is looking for her pet bat, Komori, who has disappeared. Kotaro eventually manages to hypnotize the entire female population (except Kokoa) and even Gin.
