What if.... (shinmonokami)

What if Monoma was able the copy the quirk exactly and the only thing that stops him every time is the time limit?,

This is a story we're monoma was able to copy Eri's quirk and was able to train her, but if he was able to copy Eri's quirk wouldn't that mean he could also copy One for all?

This is gonna be a shinsou x monoma story and I will add Denki and jiro because they're in like a poly relationship

Shinsou and monoma and Denki are dating but Denki is also dating jiro and jiro is dating momo, of course they will be single in the beginning,but rest assured that they will be aware but over all of will be

Also omegavers!, hopefully you don't mind this is my first time doing it,so sorry if I get facts wrong
