Kazuko Mitsumine, who runs a Chinese restaurant, is 48 years old. She has been married for 22 years and spends nights with her husband about once a week. The husband is currently addicted to shogi and goes out to play as soon as the store is closed, so the number of times he plays is decreasing. The motive for appearing in her AV is revenge on her husband. She found out that her husband was playing, so she said, "If you play, I'll be in AV too."
