Io Iori is from Kanagawa Prefecture. She started cosplaying in her third year of high school and made her full gravure debut in 2019, winning an Excellence Award at "Gravure of the Year 2019" that same year. With a petite 151 cm frame and a J cup, she has been described as "2D that goes beyond 2D."
What this site most wants to highlight is the special skills section of her profile: "construction model making" and "arc welding." She studied construction and welding at an architecture vocational school, and in 2020 she even worked at an architecture company while doing gravure on the side. Knowing that, it makes sense that she has a digital photobook shot at an auto repair shop called "Monzetsu Full Throttle" (悶絶フルスロットル).
On message boards, many fans praise her waistline and abs, with some saying she has "an athlete's body." Being mixed up with Moe Iori because of their similar names is a bit of a running gag. As her profile says, one of her skills is "being able to keep talking on my own," so you can enjoy plenty of her talk on her own YouTube channel (伊織いおの愛の鞭は結構イタい).
