Battlers (
They're equivalent to clubs in the human world. The only difference is the upperclassmen go on rookie hunts to find first-years and beg or force them to join.[1]
Rookie Hunts[]
Rookie Hunts (
The event begins with the teachers explaining the rules of not hurting the students but encouraging them to not rest until they find new recruits.[2]
The rookie hunt lasts for 66 minutes (1 hour), then the event becomes more tamed. Recruitment is where first-years are encouraged/required to join a battler of their choosing.[3]
Known Battlers[]
Student Council[]

The Student Council patrol
The most respected and feared battler in Babyls, the student body, is described as what demons should be. They are responsible for ensuring order and peace throughout the school. They do not waste any time getting up early to sort through files of the campus, stay in shape, discuss current status with the teachers, and tend to the grounds before classes even begin.
The student council rarely leaves their homeroom, but when they do, they are on patrol to ensure that all the students are well-behaved and not going through their evil cycles. Azazel Ameri, the president of the battler, demonstrates the council's principles by putting aside selfish ideals and focusing on her ambition. This carries with the members who inspire many students to follow their desires by working hard to achieve their goals. Though it will take time, most of the demons are returning to the old ways and prefer ideal pleasures. The student council will still fight for Ameri's ambition and the good of Babyls.
