Plot
Higanbana no Saku Yoru ni takes place in an unnamed school setting and is composed of numerous self-contained short stories, each told from the perspective of a student or staff member from the school. These stories feature bullying as a major overlying theme, as each story's protagonist is depicted as being either a victim of bullying or a bully themselves. Higanbana revolves around a series of urban legends caused by supernatural beings called yōkai, each of which claims ownership of a particular "mystery" and kills anyone who tries to investigate it. There are a total of seven "mysteries" at the start of the series, with numerous yōkai fighting each other in an ongoing turf war for ownership of these mysteries, which is granted to the seven yōkai who emerge victorious in the conflict. The stories' protagonists interact with at least one of the school's resident yōkai, who force the protagonists to deal with the consequences of their actions regarding bullying.
