Kaoru Orihara

Kaoru Orihara (折原かおる Orihara Kaoru), also known as "Kaoru-no-Kimi" (Prince Kaoru), is one of the "Magnificent Three" and the star of the basketball team, known for her tomboyish way of dress and her great athletic skills. She has a mysterious and deadly illness (breast cancer) kept secret from most of her classmates; it's only known in public that she was held back a year due to unnamed health problems. As Rei Asaka's best friend, Kaoru greatly dislikes Fukiko Ichinomiya for everything she has done to Rei and hates the very existence of the Sorority. She spends the series trying to live her life to the fullest in spite of her disease, and is the one who supports Nanako Misonoo when she is bullied and helps Rei when she gets into major trouble. She was romantically involved with Takehiko Henmi (Nanako's "brother"), but he broke it off after her mastectomy (a surgical operation to remove a breast). Kaoru's nickname comes from Kaoru Genji, an anti-hero character of Murasaki Shikibu's The Tale of Genji.

Kaoru is voiced by Keiko Toda.
