Kirin Suwabe

Age: 17 Shinobu's best friend and lover who is constantly seen in her company. She fancies herself as Shinobu's servant which she says gives her a sense of self-worth. Kirin is very much in love with Shinobu despite her feelings for Momoko, and even said that she would gladly share Shinobu as long as she could stay with her. She later ends up falling for another girl named Matsuri, who is deeply in love with her and who Kirin had sex with once in the manga and second episode of the anime. (Source: Wikipedia)
