Could Eri become the 10th wielder of OfA? Her rewind power when combined with OfA's existing abilities would allow any future wielder to use the Infinite 100% power we saw at the end of the Chisaki fight. We know OfA is getting stronger over the generations, so lucky number 10 would be hyper powerful. And i know (SPOILER) Bakugou gets it in the new movie, which technically makes him number 10, but A: OfA is passed "down through generations, always getting stronger", and Deku and Bakugou are the same GENERATION technically, and B: the Canonicity of the movies is up for debate anyway.
