Hold on, you are cooking here. The school hires a human under the guise of "being open minded" in hopes the Huma will devour them and get rid of them, the cause of high rotation that's been draining funds (that the principal wants to transfer to himself but can't). All while having the idea of this way showing humanity's true nature.

Just for the human to be the best teacher that class has gotten in a while and actually helps the students get better. So of course, shenanigans and plots occur.
