OMG how do I choose??????? i definitely agree with you on Touka. I would say Azula from last airbender and Faye Valentine from Cowboy Bebop.
Would it be trashy to say Super Sonico lol. Dark Magician Girl is mah wife, Hatsune Miku from vocaloid (if one can even call that anime), Mami Tomoe from Madoka... I like cute rather than hot girls apparently. Never watched Tokyo Ghoul (got most of it spoiled for me lol) but Touka's cute.
Going to have to agree with you on this one. My first girl crush before I even realized I was gay hah.
