Kotomi is another schoolmate of Tomoya's in the same year, but, like Kyou, is in a separate class from Tomoya. She is in the top ten for every subject throughout the whole country in standardized exam results—she always goes to the library to read extra materials, especially books in foreign languages. Kotomi is a very quiet girl and it is quite difficult to communicate with her. In her spare time, she plays the violin, although she is very poor at it to the point of causing pain to those who hear her play as a comedic effect.
