A typical class bully, Komiya Saizou attempts to rape Moka, but is knocked out by her super-vampire self, and disappears from Yōkai Academy for a while. In his true form, Saizou is an ogre and reappears when Tsukune is elected class president. He joins ANTI-THESIS in the hopes of exacting revenge, but ends up defeated when Tsukune temporarily transforms into a vampire. For hastily rushing ahead and bringing other members of ANTI-THESIS without consent, Saizou is killed for insubordination.
