Mikogami is a mysterious exorcist who is an old friend of the bus driver (and having the same creepy eyes as the latter) and the headmaster of Yokai Academy. He is always seen hooded beneath his garments and possesses extremely strong, anti-demonic powers, having the ability to seal Tsukune's ghoul nature using a "Holy Lock". He also has enough magic to create other dimensions sucha as the paradise he created for unstable and endangered beast-monsters.   ~!Mikogami is, in fact, one of the Three Dark Lords (三大冥王 Sandai MeiŌ?), the founders of Yokai Academy, and the ones who placed a barrier separating the human world from the supernatural world. He carries the Rosary of Judgement, which is used to make barriers, and is also aware Tsukune is human, but allowed him to stay at the academy in exchange for helping force out Hokuto, the Anti-Schoolers' leader. He seems to also be immortal (or at least in possession of very strong regenerative abilities), having been severely wounded (impaled in the back by the leader of the Anti-Schoolers) but recovering after. He is also very dedicated to the cause of coexestence asking Tsukune to stop Hokuto from starting a slaughter between humans and monsters. Though a powerful Dark Lord, Mikogami's sealing and barrier spells are apparently weaker than his fellow Dark Lord that taught him the sealing and barrier techniques, Touhou Fuhai. !~

By a bizzare coincidence, Tsukune Aono has accidentally gotten himself admitted to a youkai academy, a school attended by monsters. Just when he thinks he'll run away from there, he meets the beautiful girl Moka and his mood turns ultra happy. However, she transforms into her true form when the rosary on her chest is taken off, she's a super vampire!

Average human teenage boy Tsukune accidentally enrolls at a boarding school for monsters--no, not jocks and popular kids, but bona fide werewolves, witches, and unnameables out of his wildest nightmares! 
On the plus side, all the girls have a monster crush on him. On the negative side, all the boys are so jealous they want to kill him! And so do the girls he spurns because he only has eyes for one of them--the far-from-average vampire Moka. 
On the plus side, Moka only has glowing red eyes for Tsukune. On the O-negative side, she also has a burning, unquenchable thirst for his blood...

A year has passed since Tsukune was sent to the Youkai academy. Tsukune has gotten used to life there, or so he thought. As a second year, him and the girls are looked up to by the juniors. On the first day back to school, a sudden encounter with Shuzen Kokoa, takes a turn for the worst. What Adventures or should we say, misadventures await our human, vampire and friends?

All-around average student Tsukune can't get accepted to any high school save one...but on his first day, he finds the rest of the student body doesn't appear average in the least. Best of all, the cutest girl on campus can't wait to fling her arms around his neck! Wait a sec'--are those her teeth around his neck too...? Tsukune's going to have one heck of a hickey when he gets home from Monster High! But does he have a chance in H-E-double-hockey-sticks of raising his grades at a school where the turf war isn't between the jocks and the nerds but the vampires and the werewolves?
