Kyo is short-tempered, competitive, impulsive and rude, but he also has a soft side that he doesn't like people seeing. He gets embarrassed quickly and is overprotective of those he cares about. Some of his classmates call him Kyon-Kyon (in episode three of the first anime, which made him angry), Kyon or Kyon-Kyon (normally by Arisa Uotani), or Kyonkinchi which means 'Lucky Kyo', normally by Ayame Sohma and Shigure Sohma who both enjoy teasing him.
An example would be that at one point Shigure pesters him about the reason he hates Yuki and Kyo stomps off to the forest, ready to cry. He also has a strong hatred for leeks, and the smell makes him sick. He also hates green onions and miso, unless it's in soup form.Tutorials: Commission by *ninjapirate10194.
