I need some extremely violent anime.
The only one I can think of is Ninja scroll.
Mad Bull 34
Card Captor sakura
Sorry that I don't know of every anime in existence.
Did you really expect to know about BAOH when the only violent anime you've seen is Ninja Scroll? Just check it up on google or wikipedia or something
Baoh wasn't violent. It was funny though, and good if you're an Araki fan.
Magical Girl Lyrical Nanoha
Magical Girl Lyrical Nanoha A's
Magical Girl Lyrical Nanoha StrikerS
Ninja Scroll wasn't that violent. Well, no more so than any other early 90's anime. You want something like Angel Cop.
Now THAT'S violence.
