Reemergence

(I suck at making summaries)

Seven years post war. Izuku has been quirkless as his friends are off being pro heroes.

Walking to his job as a U.A teacher, a villain jumps out in front of him, accidentally returning One for All.

It should be great, getting his quirk, well 'given' quirk back. The problem is, he shattered his arm once again while using it. He didn't get all the training back, he has to start from scratch.
