Hiyori Yoshioka is a Japanese AV actress represented by the AV agency Loop Entertainment. Admiring Kana Momonogi, she made her AV debut as an exclusive actress for S1 on October 19, 2019. She is referred to as an "innocent sister (AV actress)" because of her appearance. Her debut work ranked 11th place in the FANZA Online Sale Weekly Ranking for the week of September 18th. In January 2020, to celebrate the number of her followers on Twitter reaching 10,000, a free hug event was hosted by her management office at Lefkada Shinjuku. Having mentioned she like the band "Macaroni Empitsu" for some time on Twitter, in March 2020, her name was mentioned by Hattori, vocalist of the band, on his radio "THE KINGS PLACE" on J-WAVE. In June 2020, she was selected as one of the 10 nude beauties by GRAPHIS, and her newly-taken gravure was published in the Weekly Post. Having video game (especially FPS) as a hobby since childhood, she has found excitement by putting the vibrating controller in her crotch while playing Katamari Damacy. While being slim with a bust size of D-cup, she was oversized when she was in junior high school, and later lose 7kg when she got into high school, so her breast remained relatively busty. Her first experience was with her boyfriend, a first-year high school student who looks similar to Yusuke Inoue from owarai duo NON STYLE, and they were dating until graduation. At the beginning of her debut, she felt difficulty with AV and wanted to disappear, but she thinks "if I didn't do this (AV), I would end up being just an ordinary person, and the media world wouldn't matter." While enjoy of being evaluated and being watched, she is considering expanding into other media beyond the adult entertainment, "I think it would be fun if I could appear more in media that I like, such as my favorite music, games, and comedy." Although she started off shaved in her debut work, her pubic hair has grown back since her second film.
