Saito High is not your ordinary school—it harbors spiritual entities and boasts a principal who collects occult artifacts as a hobby. To safeguard the school, the Holy Student Council, chosen by prophecy, must grapple with their own inner struggles. Haruto Houjo, the council president, can summon spirits but longs for a normal life despite the principal's influence. Kazumi Ryodo excels at being possessed and harbors a curious fondness for Hanako. Lastly, Mutsuki Asahina, a skilled exorcist with a penchant for young boys, completes the trio. Tasked with maintaining order at the school and protecting the world from supernatural threats, these three find themselves entangled in bizarre and humorous escapades.
