Sorry to dissapoint you but they are high schoolers, 1 girl wears a bikini in one scene that's about it if you get aroused from drawn bikinis ...
You gotta decide if they are children drawn too old (sexualized) or teenager drawn to young, watch the anime. It's like an accusation lottery in here ...
Both are exclusive (and false) and you can't even decide which one is the problem here since this is a witch hunt after that strike witches crap(no pun intended), nothing more...
When you post pictures of little girls here, these things tend to happen. The only people to blame are the ones who made the thread in the first place. It has been made obvious that kind of stuff is unacceptable here and why people keep posting them is beyond me. So the choice is either stop posting these things, or go somewhere else.
