Rias Mizu Tani has lived abroad for most of her life. She spent her early childhood in Japan, but moved overseas after elementary school and attended local schools there. As an adult, she married a Japanese man she met abroad, and last year returned to Japan due to her husband's work. Adjusting to life in Japan has been fresh and enjoyable, but she's found limited opportunities to meet people and her chances for sex have decreased significantly. Japanese men tend to back off when they learn she's married and serious, leaving her sexually unfulfilled. Seeking excitement, she joined an affair dating site and met a male AV actor. Intrigued by him, she gradually became interested in appearing in adult videos herself.
