Tsukune Aono is an average teenager who is unable to get into any high school because of his bad grades. However, there is one golden rule at Youkai Academy-all humans found on school grounds are to be executed immediately!
All students attend in human form and take normal academic subjects, such as literature, gym, foreign language, and mathematics. Youkai Academy is a seemingly normal boarding school, except that its pupils are monsters learning to coexist with humans.
