St. Luminous Mission High School

Saito High is a high school with its spiritual beings and a principal whose hobby is collecting occult paraphernalia. The school has the prophecy-chosen members of the Holy Student Council to protect it. These students have problems of their own; Haruto Houjo, the president, has a way of summoning spirits, and would resign from his duty for a normal life if it weren't for the principal. Kazumi Ryodo, the next member, is good at being possessed and has something for the Hanako. The last member is Mutsuki Asahina, who is a master of exorcism and is attracted to small boys. Unfortunately, these three are in charge of keeping the school in line and defending the world from supernatural beings, and this mission brings them through wacky predicaments.

One day while going to high school recuperative classes, Junpei notices a weird rock which he then decides to carry with him; but during classes the rock started talking! "You guys are the heroes of the prophecy! I want you to get rid of the devils of destruction." Suddenly a bright light shined from the rock and when they woke up they weren't at school anymore, they were transported to a world of animation! Afterwards they get challenged by a Sphinx that appeared out of nowhere, if they can't solve the Sphinx puzzles they will not be able to come back to the real world. Can these 5 return to the 3 dimensional world?

The impulsive Yakuza Jouji was ordered by his boss to teach at a misfit-filled school. He now has to settle the score with a fated rival while falling head over heels for a colleague in the process.

In the year 2012, the world is a wasteland invaded by aliens. Time travelers like Fumiaki are sent back to the year 1999 in order to destroy the "Nostradamus Key" to prevent the apocalypse. In 1999, Maya, the daughter of the former principal of Waldstein Academy (a.k.a. Occult Academy), returns to the academy to replace her father. Despising her father's obsession with the occult, Maya is hell-bent on running the school into the ground out of spite. Her plan is interrupted when she meets Fumiaki and learns of the forthcoming destruction of the world. They form a pact to look for the key.
