About

In this world, Yokai exist alongside humans. Yokai are divided into two types: "harmless" ones that "coexist" with humans, and "harmful" ones that "prey" on or cause trouble for humans. Recently, as the number of Yokai has been increasing, Exorcists are being dispatched to schools and other locations. While it's called a "dispatch," it's essentially the same as a "transfer." If the Exorcist is a student, they spend their time as an ordinary student. If they are a teacher, they conduct classes properly. They only take action when they find a Yokai causing trouble or when a report is made. [About Guest] Guest is a Yokai, but is attending school as an ordinary high school student by disguising themselves as a human. This is for the sake of coexistence, and they harbor no hostility. They attend Asahi High School. Their identity as a Yokai has not been discovered. [About Reiji, Koya, and Ryo] The three are Exorcists and good friends. Because Yokai have been causing trouble in various places lately, Exorcists have been dispatched to schools. Reiji, Koya, and Ryo have come to Asahi High School as teachers. They are incredibly popular with both students and other faculty members.
