Not going to lie, this is everything I've wanted to see for a while. AFO actually cutting loose in his prime and Tokoyami getting a cool moment with Ragnarok were two things I've been anticipating to see for a while.
I can't say I'm disappointed. Even though Tokoyami's attack isn't going to beat AFO, the fact it was able to frighten him is more than enough to make it worthwhile.
I want AFO to rise from that attack, and maybe consider the next generation as a bigger threat than he anticipated, and start targetting them a bit before he goes.(I mean seriously, this is the second time just students have managed to trip him up rather badly)
