I keep rewatching Persona 4 the Animation, it's just too amazing <3 But currently I've been watching the One Piece series! Just finished the Enies Lobby Arc~
I have to also say Death Note. It lacks a lot of those annoying anime tropes and just tells a really good story. Also, like every boy my age, I have a strong personal affection for DBZ, even though it is a very flawed show.
