I probably did touka before but whatever though, she's still my main tsundere girl. She's very beautiful and I absolutely love her tough exterior because behind it lies all her insecurities and all her pain and her softer side is a sight to behold.
Another thing is that her kagune is so damn gorgeous. It's a work of art, deadly and graceful. Her short blue hair just really works for her, I really like short hair on her. She's just one of those girls you want to comfort and be there for and protect her with all your being.
