I'm on Chapter 20 right now, and I love the dynamic with the rest of the class so far, although it is a little bit consternating that they haven't noticed all of the obvious "I'm going to grow up to be a villain" signs from Kaka face.

Asui Tsuyu or whatever the Frog girl's name is is great as well. That stare and perma-frown are also great in that they start off offputting, go into creepy territory, and then out the other side to hilarious, once you start to notice the more subtle changes in her facial expressions.

Trying to remember what all All Might's design reminds me of, beyond a Guile with eyebrows and Superman.
