I can't remember the name of the show or any of the characters, but the premise of the show is along the lines of a boy who meets a strange girl who turns him into her guardian and he can't die, so every time he gets injured his body automatically heals itself or something like that, and he has to defend the girl by fighting other people who also have guardians who can't die. and the one scene that i remember from it was when he was talking to a girl he knows right after he was in a fight and his head starts to fall off and he has to push it back up into place and it was really funny but that's all i really remember from it and i'd really like to see it again so any help would be much appreciated.
