... magical girl? Has the anime already reached the murderloli or is it... I think there was another magic-y thing? Pretty sure. Lore-whatsits thingjigger. It's been a bit since I read any of the manga. Hard to remember that one, since as near as I can recall her character is half-way identical to like fifty other anime characters, right down to the character design :V
But nah, with the manga the rape is pretty straight up and only a step or two from outright "Here come the mosaics" explicit. Doesn't happen to the any of the main characters (at least up to the point I reached), but *shrugs*
Though yeah, if you're looking for more explicit gore and nudity and whatnot, you'd want the manga. I'd probably say stick with the anime, though, depending on how badly they ramp up the fanservice bits in compensation for... well, removing the more explicit fanservice bits. And the gore, and the rape, and the etc. Since toning all that down would probably leave room to make a more thematically et al consistent work.
E: Oh, it has reached the murderloli. Hell, I'd almost suggest reading the manga just so you can give a report on the contrast, because if all she did was was beat some dudes up there is a hell of a character change going on there :V
E2: Pretty sure you're talking about the orgasming berserker I mentioned way back, anyway.
