Kyo Sohma
Kyo Sohma, aged 16–18, is cursed by the cat, an animal not in the Chinese zodiac but which legend says would have been if it had not been tricked by the rat into missing the induction feast. In an author's note, Natsuki Takaya described the character of Kyo as a powerful force that pulled the story of Fruits Basket along. Kyo is depicted as an orange-haired young man who is short-tempered and charismatic, if initially awkward around people; Arisa Uotani once calls him "anger management boy," and Yuki Sohma expresses envy of his ability to make friends easily. He is also fiercely competitive, and can be easily manipulated into doing things he does not want to by turning it into a competition—especially against Yuki. As the cat, Kyo hates Yuki, the current rat of the zodiac, whom he sees as never having to work hard at anything, and has dedicated his life to defeating him. Shortly before the series beginning, Kyo made a bet with Akito: if he defeats Yuki in a fight before graduating high school, he would officially be accepted as part of the zodiac; however, if he does not, Kyo would be confined inside the Sohma estate for the rest of his life. Despite many months of strict training, however, Kyo never lands a decent blow on Yuki. Their rivalry distresses Tohru Honda, who likes them both, but she comes to worry even more when they do not fight. The two eventually tell each other, during an argument, they envy as well as despise each other and come to a truce for Tohru's sake.
At the start of the story, Kyo moves into Shigure's house with Yuki and Tohru. When Kyo was young, his mother died in an accident rumored to be suicide over her son's curse, and after his father rejected him, Kyo was taken in by Kazuma Sohma. The two love each other as father and son, but Kazuma insists he continue to live with Shigure because he believes Tohru is helping him open up. Aside from his foster father, however, Kyo pushes away the people who want to help him, because he is ashamed of the true form of his zodiac animal—a grotesque, foul-smelling, monster—which he turns into when his bone juzu bead bracelet is removed. When Tohru sees his true form, however, she is initially repulsed but follows him to beg him to stay with her, which strengthens their bond. However, Kyo also blames himself for the death of Tohru's mother, whom he could have saved at the risk of turning into a cat, and he was shaken by Kyoko's last words, "I'll never forgive you..." As the story progresses, Kyo falls in love with Tohru, but he refuses to subject her to the pain he is convinced he will cause, so when she confesses she loves him, he rejects her, calling himself "disillusioned." Only when Uotani, Hanajima, and Yuki impress upon him how deeply his rejection hurt Tohru does he get up the courage to accept her, and when he does finally confess to her, his curse lifts—along with the rest of the zodiac. In the last chapter, he and Tohru begin moving out of Shigure's house to another city, where he will study at another dojo in preparation for inheriting Kazuma's, and in the final pages they are shown as a loving couple with a granddaughter.
