Kamome Academy is famous for its rumors regarding its Seven Wonders and supernatural occurrences. Nene Yashiro, a girl who wishes for a boyfriend, and a first-year high-school student, summons the Seventh and most famous Wonder, "Hanako-san of the Toilet", the spirit of a girl who allegedly haunts the bathroom and can grant wishes for the right price. Upon summoning her, Nene discovers that "Hanako-san" is nothing like the rumors say; Hanako-san is a boy. With a turn of events, she is spiritually bound to Hanako and becomes his assistant, helping him destroy evil supernaturals and change rumors in order to maintain the balance between the spirit world and the human world. Along the way, Nene learns about her connection to the spirit world and the dark secrets regarding Hanako and his past.
The Seven Wonders of Kamome Academy are the seven most famous supernatural rumors in the school, and their corresponding supernatural serve to maintain the students' safety from murderous supernatural. Leading them is Hanako, who is the Seventh and most famous school Wonder. Each one has their own Boundary, a divine yorishiro, and an aspect of the school that they control. Their Boundary is a section of the school where their power is the strongest. Boundaries are the 'sea' between the Near Shore, where the living reside, and the Far Shore, where other apparitions exist and thus contain a small amount of water on the ground. A divine yorishiro is an item they cherish that acts as the source of their power. When a yorishiro is destroyed (by removing its seal), the Wonder's designated seat as a School Wonder and their power is removed. Thus, they are usually kept in the deepest region of the Boundary or safeguarded by the wonder themselves.
No. 6 – The Reaper
Apart from the Seven Mysteries, there are other, less powerful supernaturals that roam the school. They rely on student rumors to gain power, unlike the Mysteries who already have theirs so popular and widespread among the student body.
