As for topic- Naruto obviously~ and many more but I would add here- Noragami and Noragami Aragoto- one of my personal "forever the best" Death Parade (rather mature show, "Death Parade Is About Life, Death, and the Darkness of the Human Heart") Kyoukai no Kanata- supernatural forces, fighting etc. with little bit of pervs :P Not "The Best Around" but sure nice to watch Fullmetal Alchemist:Brotherhood- one of those The Best. and more~ and mooooooreeeee~~ :P
Haven't watched a few in a while but: Code Geass, Sword Art Online, YuGiOh GX, Naruto(not finished tho), Hetalia, some bits of Bleach, some bits of One Piece, Inuyasha, some bits of Ghost Fighter, some bits of Ranma 1/2, some bits of FMA. I know there are some more, but I forgot.
