[@TwilightDragon] Oh. Basically the premise is that our characters are high school students in the worst school ever, Akuro High. It is filled with thugs, thieves, gangs, and delinquents and that is exactly what our characters are. The only reason anyone goes there is that no other school would accept them because they are the scum of society. The school is filled with students who are somehow monstrously strong, much stronger than the average human. The strongest of the students are the leaders of the four top gangs, the Four Kings. What's odd about these students is that they seem to have powers, rumored to at least. The rumors are true however; those students are demon contractors, people who have formed a pact with demons so they can use their powers while the demons can stay anchored in the human realm. Demons are enamored with the life styles that the humans have and wish to indulge themselves when they take on a human form. 

This world however always has demons causing havoc and misfortune, but an organization that works in the shadows takes care of these issues. They are kept a secret to the general public, but every government and business supports these people and backs them financially, calling upon their services when needed. Akuro High, is a base for these Exorcists and these students will unknowingly become some of the most important people in the world. 

It's a shitty summary. ^^;;;
