Bio: Kaorin is a student who goes to high school. Like Chihiro, she doesn't appear as much as the other students. Chihiro seems to be her best friend. Kaorin has a very strong personality and is obsessed with Sakaki. Whether this is a fan worshipping an idol or being in love, I can't say for certain.
Opinion: She has a strong personality for one thing, so when she appears on camera the scene is certain to come alive. She's also one of the cuter girls in the series. In the end she leaves a strong impression almost every time she appears in the series.
