Yumi Omura is a 17-year-old girl who works at the Japanese pub, My Pleasure, alongside Hideki. She is the daughter of the club's owner. It is initially implied that Yumi was interested in a relationship with Hideki, but as the series progresses it is revealed that she initially approached him because he also worked at Club Pleasure, and that she thinks of him as a big brother. Throughout most of the series Yumi has an inferiority complex toward persocoms, and becomes upset at any mention of a human-sized persocom.
