The show was interesting at first, but then they have a high school girl strapped down by aliens trying to SA her. The whole scene is played very light despite what's happening. Also, another high schooler gets SA'd off screen as well
Fuck that and not watching more
It is in the manga but the anime has some particularly egregious angles that make it worse imo. There's one other scene later in the manga at an onsen that's uncomfortable too. Just a heads up if it's something you're gonna continue
