Masami Ichikawa from Tokyo joined SOD in 2014 and was assigned to the publicity department. On January 8, 2015, she made her official debut with her first work, "Soft on Demand Publicity Department: First-Year Employee Masami Ichikawa (23) AV Appearance (Debut)!!". SODstar also announced that she would be the brand's first exclusive actress from SOD's female employees. Just one year after her debut, she received the "Talk of the Town Award" at the DMM Adult Awards, and along with Yua Mikami, she joined the second generation of Ebisu Muscats. Later, she took over the leader position after Kirara Asuka's retirement, and within less than two years, she rose to become one of the top actresses in the industry. What sets STAR-786 apart from typical pure chikan series is that the "Chikan OK Girl" project is a signature work of Natural High, a subsidiary of SOD. The significance of this work is that she performs as a SODStar exclusive actress in another company's flagship production, making it a highlight for both companies, and it's an extreme chikan project. Actresses in this series must experience the pain and pleasure of being molested in various scenes and situations. The film features five chapters and four different scenarios, facing endless molesters, from subtly resisting to climaxing in surrender, with a gradual buildup. Combined with Ichikawa's elegant face and innocent demeanor, her portrayal of the pitiful vulnerability under molestation is one of the reasons it became one of her representative works. Fans who enjoy chikan series and those with a glasses fetish absolutely cannot miss this film. Due to health reasons, Ichikawa first announced a hiatus at the beginning of 2020, and this year on April 11, she personally announced her official retirement from her AV actress identity via live stream. In just eight short years, she went from being the flower of the publicity department to a SODstar exclusive actress and a favored talent under T-Powers, the largest agency in the Japanese AV industry, putting a perfect end to her brief and brilliant AV career.
