Sekkusu friend Karenna. She used to believe sex was something meant to bring men pleasure, but after being groped by a middle-aged man on a train, her perspective completely changed. Now she harbors a deeply masochistic side. Whenever aroused, she exhibits the bizarre habit of riding packed commuter trains. A former idol and married woman, she possesses a deviant allure, becoming intensely excited only in scenarios where she's forcibly taken against her will.
