Yumihiko Natsuka is a 26-year-old woman in her third year of marriage. Standing at 171 cm tall, she has a slim and stylish figure that often leads people to mistake her for a model. She is always cheerful and friendly, with a wonderful inner self as well. Although they are a harmonious couple and have even discussed having children, their busy schedules have led to six months without sex. Still young at 26, she wants to shine as a woman and future mother, which is why she decided to appear on the show.
