Chiho Yamaguchi is a 24-year-old gentle, big-breasted young wife living in Shimoda, Shizuoka Prefecture. She and her husband run a minshuku (family-run inn) at his parents' home, and she's a beautiful mother with a sweet, easygoing personality and a 3-year-old child. Due to poor off-season revenue from the inn, mounting financial pressures from daily living expenses and child-rearing have led her to make the decision to participate this time.
