This a very good Anime series. The Animation is good, the action scenes are of high quality. The story line isn't too complex, but it keeps you interested. It's not all serious, there are funny bits in it. No nudity, but some subjective adult humor. Characters die in the story, but hey, its about CORPSES! I'm hooked on it. It does involve characters who are in school, but the whole anime doesn't revolve around school. I would suggest it to anyone.
