I've mentioned it before in comments a few times, but my entire interest in the show as a whole started and ended with the fact that Mori Calliope sings the ending theme (and it's good as hell), but I didn't really have much interested in the actual setting of the show mainly because I checked out of American hero stuff with Endgame, but if any of y'all have seen what's available right now, what's your opinion on it?

Edit: posting the actual animation with the opening and ending themes for the sake of posterity:
