Mei Sunohara from Clannad because she is cute, has a really cute voice, is the sister to the hilarious Youhei Sunohara, and also I like her because she's my favorite anime character! (Which is obviously not why I like her...)
Naruko Anjou from Ano Hi Mita Hana..it's longer than that but you get my point XD,I Love her because She's just so quiet in a sense,she's really cute (I don't think I've ever seen anyone blush as much as her),She always tries to help Jintan,she's just so amazing in every sense in my opinion!:3
Misty from pokemon. Then some mega tie for second with Tokine Yukimura, Maka Albarn, and Sakura from Kaichou wa Maid Sama.
Wait .... when the ponytail is on the side it still counts right? Oh well, I like her because she is violent in a funny sort of way. And let's Ash into the mix with a comic!
