Hell Teacher Nube

Haruto Hojo is the son of a priest, which might sound normal. However, his school is the ground zero gathering point for everything ghost, spirit, and likewise, thanks to the obsessed (and also a ghost) headmaster of the school! In order to make sure everything runs normally, Hojo (who just wants to live a normal life), along with Mutsuki (prodigal Japanese priestess), and Kazumi (a frequently possessed monk), complete tasks that only seem to make the school more strange and hectic!

In the distant past, a ferocious monster plagued the land. This creature of fury was finally subdued when a traveler challenged it to a battleand drove a spear into its body, pinning it to a massive rock. A temple was built above it, and thus, the house of Aotsuki was founded. Fast forward to the present, when young Ushio Aotsuki unwittingly releases the beast and names him Tora, much to the monster's dismay. Now, with plenty of stray demons wandering the city, Ushio must defeat the evil with the ancient spear, before being eaten by Tora as a snack!
