This is a behind-the-scenes documentary revealing everything from her first-time shooting to her AV debut. She's a cute girl you'd see on the street, a 21-year-old current college student named Risa from Tokyo. With her G-cup beauty, she's popular with guys at university. While she's experienced regular sex with guys, she's never had the pleasured sex she sees on SNS. Wanting to experience that before becoming busy with work, she contacted a private shoot instructor. This is her prologue as an AV actress, her true first shoot, and then, after being named [Rino Kisaragi], she has one last intense sex with an AV actor before leaving university life behind. This 130-minute film captures it all!
