Any other good war animes, or a ACTUAL GOOD anime, like Trinity Blood or Vampire Knight?

Well, I got a few animes that may fit the list

Gregory Horror Show
Elfen Lied
High School of the Dead
Hellsing Ultimate
Attack on Titan
Corpse Party
Dragon Ball Z Kai
Code Geass
(Not. All are very violent)

Let's see... Black Lagoon, for sure. That's a must see if you like mature anime. And do watch it in dub if you can; it really brings the show together. *pic*

Romeo x Juliet is more romance based, but has somewhat of a war-based conflict. However, the main genre IS romance, so if you don't care for that, I wouldn't recommend it.

The Legend of Legendary Heroes is also fantastic. It can get violent, but not to the level of Corpse Party or anything like that. It's a really good fantasy-war anime.

Attack on Titan is an excellent anime that I'd probably class as a war anime, since it features the war between humans and titans.

Also, Naruto Shippuden, though not a war anime in itself, includes a long arc about the fourth great ninja war, which is frigging epic! That arc is currently ongoing, too.

Grave of the Fireflies is a Studio Ghibli film set in the war, though to be honest I just found that one really depressing.

Shiki is my favorite vampire anime. (It's also horror, my favorite genre).

Naruto , Bleach, One Piece

These 3 animes have super Duper wars in it.............he he eh h
