My two избранное are C.C. from Code Geass and Lucy/Nyu/Kaede from Elfen Lied but since I am currently watching the секунда season of Jigoku Shoujo, I feel like posting my third favorite, Ai Enma.

Both seasons of Squid Girl (that's the show's name too) are on Crunchyroll. If Ты don't mind watching a few commercials, you'd be helping the producers of the shows by watching it there. The first season dub is also on Netflix if Ты have that. link
