Welcome to Akuro High School, a lawless school infamous in Tokyo for their hoodlums. The school is run by 4 gangs, their leaders are known as the four kings are supposedly the most feared students within the student body or maybe the entire school district. There is always a power struggle between the gangs to take over the entire school and theses struggles can spread into the town. This may sound horrible at first and believe me it is, not all students here are like this. You see, many of them come from families that are barely getting by and the parents are trying to get their child an education even it is in this hell hole of a school. Believe it or not you can actually form tight friendships here because life will be tough if you don't have a good friend to watch your back in this school. Well students here will either welcome you to this school with open arms or with hands holding bats depending who you are and what you have done so build a reputation to make them respect your...oh and I nearly forgot! There have been strange rumors regarding to the school, most notably the rumor of students using powers, but the man who saw it was really just a drunk so they didn't take him seriously. This school is much more than just your shit hole school, it has another purpose. What is it you may ask? Find out for yourself.

Demons have always had a strange fascination with the human world because of their culture and the products that they produce, especially Japan. They will take on their human forms and then converse with humans so that they can get an understanding of how things work. It is important for them to understand how the human world works because they need to blend in so they can just enjoy the leisures of a human. What they also love is watching a human's life, especially when they are hoodlums and gang members. If they think that a human is worthy of forming a contract then they will appear in front of that human and tempt it with power in exchange for living in the human world with them instead of going back to hell. When a human forms a contract then their bodies are enhanced in every way and they get the demon's power.
