Hi this crossover is Rwby, Highschool DXD, MHA, Naruto, Symphogear, and more

This Union Academy is a school of false heroes who use their power for hunger, frame, hurting powerless people

(You are the only powerless boy in the academy who gets bullied for being a powerless weakness, your former friends betrayed you, the Headmaster and Students don't want to help you and your 5 girlfriends cheat on you with your bully)
