Going to second Fullmetal Alchemist. One of the most bad-ass anime I've ever watched. I liked the first series too but then I haven't watched the second series yet XDDD. Also you might like Tiger and Bunny. And I'm just about to watch Ano Hana but from what I've heard from everyone, it's a really good anime :3.
And I saw someone recommend Shinsengumi animes, so I'll recommend Gintama, which is a super hilarious gag take on samurai and the Shinsengumi. Though I say watch the more serious Shinsengumi anime first because you won't be able to see the Shinsengumi the same way ever again after watching Gintama XDDD. (It's long though, around 200 episodes :3)
