I’ve read they were some creepy stuff in this anime, but beside that one scene at the beginning where Rico is naked for every students to see (which is questionable I admit) I’ve never been disturbed by anything… I didn’t watch the movie between season 1 and 2 (makes s02 quite hard to understand NGL), and I’ve really enjoyed the world building and emotional journey depicted all along the way. I don’t know where is the perverted stuff you guys keep referring too…
Not really about generations, it’s more about manners, anyone blasting shit around people who never asked for anything deserve a kick in the groin. Bonus kicks for people ruining the calm in a natural landscape.
