Third grader Yuki Tachibana lives in two worlds. In one, he is a loner ridiculed by his classmates and reprimanded by his teachers for telling stories of supernatural beings that only he can see. In the other, those supernatural beings vie for power with malevolent spirits who bring chaos into the school, the students' lives, and nature itself.
