Cerberus
A prestigious but notoriously short-tempered professor at the Barbirus Academy. Kalego's got a serious chip on his shoulder when it comes to demons with laid-back personalities—he just can't stand them. His life takes an unexpected turn when he ends up contracting with Iruma Suzuki, a human who somehow landed in the demon world. The whole situation clearly bugs him, but that's kind of become his thing at this point.
