I know you've read a lot of these, so i will be short: Bullied Y/N tries to prove that you can be a hero even without powers, gets killed by the bullies, goes to another world, gets stronger, earns a lot of achievements, gets a lot of girls (some of them will be Yanderes. Yes, you heard me right.), returns to his own world, beats the shit out of his bullies and fake heroes, changes the academy for good, the end. Yeah, that wasn't so short. Anyway, have fun.
I only own my OC.

You have no power whatsoever. You have been bullied because of this by everyone except for the headmasters, teachers, few loyal friends and a little sister. You had enough of everything and leave a letter for them but most importantly to Glynda Goodwitch who you is your adoptive sister that adopt you so you can live with other than your hell. You were then disappeared until 1 month later you return and show everyone that you're stronger than before
You: You may be stronger than me on the ground but in the dark blue sky, I'm stronger than you
