The show is overall violent but gets even more so in Episode 14 and beyond. During the Truth of Zero arc that deals with a murderous cult, people are shown being cut into pieces, a child getting her eyes gouged out (only the aftermath is seen), and much more. Though the most brutal part is where a character is held up by invisible hands and slowly has her limbs and neck twisted as they were still alive. In another episode, the main character gets his entire body frozen solid and his head knocked off. (not very graphic) Dead bodies can be seen of some villagers.
A teen boy dies in several, often brutal ways. Such as getting stabbed, getting sliced open, decapitated, freezing to death, and getting his head smashed.

Strong animated fantasy violence. This is a very violent show. The main character is killed many times in increasingly brutal ways. Such as being gutted (his guts are not shown, but mentioned), being beaten by a mace, losing his arm and being crushed. (Uncensored and Director's Cut version shows his eye rolling through blood), committing suicide by jumping off a cliff (Impact heard but not seen).
