My two favorit are C.C. from Code Geass and Lucy/Nyu/Kaede from Elfen Lied but since I am currently watching the detik season of Jigoku Shoujo, I feel like posting my third favorite, Ai Enma.
What anime is Squid Girl from please tell me so that i can watch this anime on youtube than i will tell anda if i like it atau not than i will goin a fan club of this anime.
Both seasons of Squid Girl (that's the show's name too) are on Crunchyroll. If anda don't mind watching a few commercials, you'd be helping the producers of the shows oleh watching it there. The first season dub is also on Netflix if anda have that. link
