Was stated that if they evolved enough, the sisters would be visible eventually, thats why Van was reluctant to use THAT kind of armor again later on, but when he found the sisters it was the only way to help them
Van was able to heal then of their burns, Van didn’t want to turn them into living armor using the bikini armor (the dad was the one who insisted but he later regrets it as he didn’t realize how they’d look after gaining the skill to become visible), [...]
I mean cannibalism, strictly speaking, is one species eating their own species. It causes many physiological issues which is why we’re adverse to the very idea of humans eating humans or other species eating their own
what i like is that they become so powerful that they can easily kill trash like the ones who killed and raped them. you can try to reduce their character all you want but it wont change the fact that Van's maids are badass.
It absolutely worked and if they want to, they can just turn invisible again. I also agree that you reducing them to being rape victims is stupid. That's exactly why they started calling themselves "rape survivors" which is really fucking retarded.
If all you can do is mindlessly complain about non-issues that have in-story reasons to happen/exist I suggest you fuck off... you clearly just want to bash this manga because you got a grudge for whatever reason.
