All for One has a backup plan if he can't kill One For All, he will just send the quirk back to a weaker form so he could just kill the child. What he didn't anticipate is that One For All would only go through to the past with the Ninth. Time travel Izuku fic with two Izuku's and no name of "DeKu" because I hate the fact he chose that name. Also fuck nighteye, you're an arse and have no right to judge who gets One For All.
