A new semester begins for Aono Tsukune at Youkai Academy — the academy that only monsters attend — and his troubles are far from over:

A female gang of girl-obsessed first-year students makes itself known on campus, giving the second-year girls Moka (vampire), Kurumu (succubus), Yukari (witch), and Mizore (yuki-onna) a hard time. One of these newly arrived first-year girls is a vampire, holding a deep grudge against her older sister, who happens to be Ura Moka — accusing her of not being true to herself when sealed in her Akashiya Moka form.

Will Tsukune succeed in healing more ruffled hearts?
