Tsukihi is my second favourite character of the series! *--* It was almost love at the first sight because as "imouto" I recognize myself a lot in her! Especially with her attitude, I think she's deeply obsessive with her big brother almost as I am with my big sister! I was very happy to know her better in Nisemonogatari, it was really a big chance to see more of her real self. She was one of the most unlucky characters because of what happened to her, but at least, she was saved by Araragi-kun that is everywhere- I love the relationship she has with her sister!! They're so close that the most of the times people address to them as a single person, moreover, they're the "Fire Sisters"! I hope so see her soon in the new series! And I hope to see this boyfriend she talked about to Araragi-kun... though I'm almost certain that she's not that interested in him! XD
