In June 2008, a married woman working at a popular high-class hot spring inn in Oita Prefecture applied to appear in an adult video through an online bulletin board. In reality, she was a beautiful 40-year-old housewife with a voluptuous figure. Due to her demanding job at the inn, she had been experiencing a sexless marriage, and she boldly revealed her 107 cm (35.4 inch) massive breasts, making her AV debut. Her erotic appearance quickly drew significant attention from AV fans, but news of her involvement eventually leaked out at the hot spring resort and reached her husband. As a result, she tearfully retired from the industry. This release marks the long-awaited completion of the deluxe collector's edition featuring the renowned Haruka Senzaki.
