the high school is built on a ranking system. the ranking system is based on who has the strongest group. there are monthly tournaments held to judge the strength of the groups. any group can challenge a stronger group and if they win they will get the higher groups rank but if they lose they are disqualified from the next tournament.
the school runs like any other. you go to class and then lunch and then class again. but if you have challenged or been challenged to a battle after school you go to the arena and fight to see who is the better group.
the rp would mix the fighting in but it would mainly be concentrating on the social interactions within the day to day life of the students.
