User Summary Koyomi dreams of being a teacher but after she applies to many schools, she gets nothing but rejections. One day, she finally receives an acceptance letter at school deep in some mountain. After finally making her way there and meeting a bunch of weirdos & delinquents, she arrives at the principal’s office only to discover that he’s an ayakashi! He tells her that their entire school & town harbors ayakashi (also referred to as yuuma), especially ones who cannot control their powers and would be a hazard to human beings.
