tsukuneaono

Tsukune Aono (青野 月音, Aono Tsukune) is a human and the male protagonist of the series. Tsukune Aono is mistakenly enrolled in an academy for monsters, where he meets Moka Akashiya, a vampire who takes an interest in him and the sweet flavor of his blood. Despite liking Moka, Tsukune soon encounters Kurono Kurumu, Yukari Sendo, Rubi Toujo and Mizore Shirayuki, all of whom develop feelings for him and become his closest friends. Tsukune is a loyal friend, member of the school Newspaper Club and the only human to reside in Yokai Academy.

Tsukune is later injected with Moka's vampire blood and undergoes several major bodily changes, emerging as a human/ghoul hybrid and possessing semi-vampiric powers.
