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.
