AV expert Ichiken Kanshun states that Sato Riko is an amateur actress whose films don't sell well, yet her income is vastly different from that of the company's top actresses. Before entering the AV industry, she worked at a golf course, but because of her dreams of becoming an entertainer, she unexpectedly entered an entertainment agency, only to be told during her interview, "This is where you shoot AVs."
Hearing this, Sato Riko thought that making AV films could also lead to becoming an entertainer, and with her impressive G-cup breasts, she should be able to adapt to the industry quickly. So she worked while making films, eventually debuting as a comedian, but unfortunately, she didn't achieve much success and had to return to making AV films part-time while working at a hamburger shop.

Then in 2019, one of her films became quite popular, garnering over 880,000 views, giving her a taste of fame. However, as an amateur actress, Sato Riko revealed that her income wasn't as lucrative as she had imagined; her highest record was "only" 2 million yen, and at one point, she had no films to make and had to go back to part-time work, which was really tough.
