"You can just call me glasses."

Miko has just started attending her new school, thinking it was bridal school. Instead, she learns that she has been tricked into going to a demon slayer school. The dense and naïve Miko gets on the nerve of the other students who see themselves better than her. When demons attack the campus and the other girls are not able to handle their own, Miko unwittingly reveals that she is the Absolute Priestess, a one in a million spiritualist that is loved by all spirits, good and evil.
