Ehhh. It's action, it's pretty kiddish when it comes to violence.


Mirai Nikki (Future Diary); Possible nudity, I haven't watched in the series in awhile and I marathoned it.
Hamatora
Kill la Kill
Magical Warfare
Broken Blade

Bold are the really violent ones. Mirai Nikki has a bad story however.

Broken Blade is amazeballs. Don't let the episode count fool you, 7 episodes, all an hour long.
