Keiko Yukimura

Keiko Yukimura (雪村 螢子, Yukimura Keiko) is a top student with a personality opposite that of childhood friend Yusuke, the two also being closer than either like to admit. Keiko's parents run a ramen restaurant named Yukimura Diner (雪村食堂 Yukimura Shokudō). After Yusuke is killed in a car accident, he is permitted another chance to live should someone, who ends up being Keiko, kiss his corpse. Yusuke tries not to involve her with his spirit detective escapades, though multiple interferences from demons prevent this. After being told an almost unbelievable lie by Botan, Keiko learns the truth when she goes with Botan, Yukina, and Shizuru to the Dark Tournament, and continues supporting Yusuke in his further adventures. Towards the end of the series, Yusuke proposes to Keiko, telling her that no matter where life takes them, they will always be together in each others' hearts, even after having to wait three years for him to return to her.

Keiko, born on January 31, is 14 years old at the beginning of the story. Her blood type is A. (see Blood types in Japanese culture) Cooking and cleaning are her hobbies.
