I'm such an anime nerd so far I've watched...
Maid la sama
Ouran High School
Inuyasha
Tokyo Mew Mew (English dub of this was like.. a nightmare)
Soul Eater (Gawsh I love this, though I really wish they made the anime like the manga... though a new chapter of the manga came out like 2 days ago.
)
Pokemon (I used to love this so much)
Fruit Basket
Spice and Wolf
Vampire Knight
Digimon (when I was little xD)
Shugo Chara
I still need to watch Bleach and Naruto... but I'm lazy. xD
