It'll be fun to see where the series will go with this new information about All for One.
It's also nice to get some background on Shinsou. I feel a bit bad for him, the moment people around him figure out what his quirk is they probably stopped talking to him, or even hanging out with him. I hope he'll appear again, I want to see him develop.
And I'm still curious about the possibility of Quirk Bullying. We know quirkless people can get bullied, and that Quirk Marriage is a thing, so I'd be strange if there isn't Quirk Bullying as well. It probably doesn't affect appearances as much as it would in real life since so many people have their appearance changed, but there must be quirks that don't fit in this society. Hand-guy might be a victim of that.
I also liked how Eraserhead actually called out the entrance exams as unfair. Didn't think of it myself back then, but he has a damn fine point. If your quirk doesn't allow give you any form of strength or way to affect your enemies, you're screwed, even if your quirk is really amazing.
