What are some anime suggestions that feature angry characters who love ripping out hearts, and other vital organs, during fight scenes? So far, I can only think of Fist of the North Star and Sword of Berserk.
An enemy of mine advocated Elfen Lied and Gantz, but those are too unrealistic. I'd prefer something true to real life, such as testosterone-willed characters with biceps ripping their shirts at the seams and eyes bloodshot from constant rage at nothing in particular.
