A great short series. It involves a bit of higher level thinking at times, but it still carries the light-heartedness as expected of a school-type anime. The series reaches outside of the school plenty of times, and there is a fair amount of character development in order to satisfy even some of the pickiest watchers. A great mystery anime, :D

Based on supernatural events. The principal, a young woman, wants to find the story about her grandfather, dragging along a school teacher who falls for her along with her journey deep into the occults.
