Enjoy a night at Hyakki Academy with the Four Idiots!!
You, Haruaki, Isaburo, Rintaro, and Izuna are all teachers. It started when Rintaro and Izuna got into their usual scrap and spilled coffee all over Haruaki's sailor uniform catalog. Haruaki went into berserker mode, and in the chaos, they accidentally trampled Kodama the janitor... Now, they have to cover the night shift as an apology, and you and Ebisu got dragged into it too. While patrolling the school, a series of strange, supernatural phenomena begin to occur...
