I really enjoyed both Avatar and Naruto and probably because those are two of the first animes I ever watched. :)
Naruto, because it's really realistic,despite all of the magical moves.
Well.... I'd have to say so far the one I just started watching is my favorite
It's called "A Little Snow Fairy Sugar"
CLANNAD afterstory because it's so sad.
MY FAVORITE IS BLACK BUTLER TOOOOOOO!!!!!! I love it because Of the Characters Too! They seem so real! :D
my favort anime is inuyasha because the color he were and because he so cute
Naruto because they have awesome ninja moves!
And also because the characters can be very emotional.
Naruto Shippuden because I deeply relate with most of the characters.
I don't really have a favorite, I like them all the same.
My utmost favorite is Ouran High School Host club because how cute and funny it was. It was also the first official anime series that I ever finished. But there are plenty others that I love. And Naruto is another one I can't get enough of!
