Commonly known as Kori-sensei, he is a teacher at Kiwiigami High School. Despite his quirky and awkward behavior, he cares deeply for his students both beloved and degenerate and only wants what's best for them. His clumsy nature also hides the fact that he's very sharp-minded, which heavily plays a role when threatening Bushtail of exposing her true intentions and calling out the principal to be a fake before succumbing to his wounds made by the Clay Doll.
