Koumoto Akane is the principal of the school Kuromine attends. Though young in appearance she is actually thousands of years old. Despite her age and power she actually behaves very immaturely and is obsessed with snacks.
She is a devil; however, the only indication of this are the two large horns that grow out of her head which she has passed off as a fashion accessory that can be removed at any time, but in reality she uses an illusion to make it look like she can remove the horns.
