Rio Hamasaki debuted in "eighteen" in 2006. After about five years, she has finally retired, much to everyone's regret! And we follow her closely on her last day as an AV actress! We see her true feelings, her true face, and her true self... While looking back on the various works she has appeared in since her debut, we see her full use of the erotic sense she has cultivated over the past five years. And then there is her retirement sex, which is the culmination of all of this.
