Even though Mitsuya was now aiming to become an actress, because of her large bust size for her age, she began doing gravure work at a steady pace.
Furthermore, since her dream of becoming an actress was being deterred due to her gravure work, she considered leaving Horipro and even sent a resume to Starbucks.
In 2006 she played in a live action movie of Tatsuya Egawa's (semi hentai manga) Tokyo Daigaku Monogatari.
Another 2007 role was in the movie "IT Bubble to Neta Onna Tachi " about a girl, dreaming of becoming a star, who travels from the country to Tokyo where she discovers young IT startups and falls in love.
She played in movie "Taksu" (2014), directed by Sugino Kiki, as a wife of a married couple who spends some times staying in Bali, Indonesia.
