I started reading a series, but then forgot it..

[Romper]

So can anyone help me out? I have a general idea of what the plot is, and it's as follows:

The president of a school's morality (rules whatever you wish to call it) is from a long line of guardians. They protect a former "Demon" bully that ruled over all the school gangs. She, or another character, sets him free to fight against a new gang and forces him to join the morality club.

Ironically, I believe I too have read that series...

...and subsequently forgotten the title. Hmmm...

I shall investigate.
