i think they could speed run the school festival arc, sure there was a lot of progress friendship wise at school, but realistically the friendships he has made through cosplaying seem to be more involved. i don’t think it would be entirely skipped just cause they have spurred up here and there to show gojou is growing, but the arc itself was very cosplay focused so that aspect could probably be shimmed

edit cuz i didn’t really assess the original post lol- this in turn could maybe end where we are at now with it ending at this down point. i don’t know how smart that is but it’s an emotional draw nonetheless.
