Compared to how she was, I think that Torii has grown a lot. She still looses her temper sometimes, but she's trying to show that she can be calm and respect other people's decisions. She's still pretty self-conscious, even if she rarely seems so. She's still protective of her friends, and ready to kill somebody if she needs to. She's past Tsu, for the most part, and has started to think about her life some more. She still wants somebody to love or go out with, but she doesn't want to seem that way. She's happy that Gio and Marcus get along so well, and she wants to see them stay happy.
She still looks up to Bran, but not nearly as much as she used to. In her mind, she saw Bran as a father, and [when her and Bran argued at their Date in Chaos] she was going to ask him and Rylli to adopt her. After the fight, she really got turned away from Bran; she was already wary of his family. She felt like Rylli didn't really like her as much as she appeared to, and she hated Natiya, so the Nikanors as a whole were getting more distant. At first, this was saddening to her, since they were originally close friends, but she's become more cynical and not as lovey-dovey towards them.
She's also gotten the same way with Katya, Kei, and Dora. At first, she was friendly with them all, but then Yoshi came it. Torii didn't see Kei as much, and now she never sees Kei; to Torii, Kei is just another friend who used to be close, then dropped off the face of the Earth - another person who abandoned her, and she doesn't care anymore. As for her Sister, Torii was very happy when Katya and Yoshi were together, but then Yoshi left, around the time that Katya and Dora were back together. Torii decided she'd rather forget Yoshi entirely for walking out like so many others. She's mad at Katya for being unfaithful and emotional, getting pregnant, and driving Yoshi away, and she's mad at Dora for having such an influence on Katya and promoting an "immoral relationship."
On top of that, Katya's lack of interaction since then has driven the two apart. Overall, Torii has grown to dislike Kei and Dora (a lot) and be dismissive of Katya.
She wanted to be an intern for the raptors. After their trip back to 2012, Torii really considered quitting. She sees that the Raptors aren't as cool as she thought, but she's decided that she still trusts them and would help them. She just hasn't tried to yet.
Yuna & Drova: Torii still thinks of Yuna as a good friend, and she's enjoyed spending time with Drova. Even when he told her about how he was friends with Octavian, Torii didn't care, because she could relate to being friends with Tsu, when a lot of people were against her. After he danced with her on Gliese (and actually showed up), Torii wants to know him better. It's not a crush, but it could become one.
Kale: Torii likes Kale a lot. She's different, but so are her other friends; Torii is the only normal human among them.
Life: Torii is still scared, or, rather, terrified of thinking about life when she grows up. She wants to stay young forever, and has an obvious plan to keep it that way. She feels cheated out of her childhood by her circumstances, and wants to keep living carefree for a while. She doesn't care what anyone else says, she won't compromise on that.
Torii doesn't show it often, but she's kind of religious. She prays and believes that people should behave a certain way, like how she said that Katya/Dora/Yoshi was immoral. She's accepting of all of her friends, but necessarily towards all humans. She's kind of racist.
She's become more distant from her parents. She wasn't familiar with her Mom to begin with, but she doesn't talk about her Dad as much. She's kind of loosing hope about actually living with him. She secretly had a dream/delusion of her, Katya, and their parents being able to get along and live together. Realizing that such a thing isn't very likely, she's not as respectful to her family.
She hates Bielefield and the government, even though she lives there. After the NMJM was formed, Torii was distrusting of them. After Valentine's Day, she hated them. She also thinks that the people of Bielefield are ungrateful, annoying, snobbish assholes. and that their behavior would never be accepted in her home country. On that note, she's very patriotic towards her home country, and loves Russia as well.
