She's a 16-year-old earth pony, Jikan's ex-fiancé, chosen by Masato Kunai and Sakura Haru to make Jikan raise a family with her, as well as them and their ancestors, Yoko did her best to retain Jikan by her side (a even though she didn't really love him); By mistreating and humiliating him, and he even always said that he is her husband (although they have never really married). One day she abandoned him and that caused Masato and Sakura to press their son Jikan once again to do as they ordered. At that time, Jikan has not seen her again, but it was for the best, since Jikan got rid of so much suffering when leaving his homeland.
