@honeybadger18 their not that over-sexualized, most of them are pretty much just normal with the exception of one of them, but it's explained in a way for her ability (I may be wrong about this part fair warning) so you should be fine
The random cheap gags during tense moments ruin the atmosphere. The plot armor, the useless side characters like tamaki, the mindless cheap fanservice... sigh. Could've been a really good manga, ended up a mediocre shounen manga
