Iori Kousaka (高坂 伊織) works as the graphic artist at the eroge company Flower. Her responsibilities include coloring character artwork and backgrounds from the main illustrator, assisting with cover box layouts, and participating in debugging. Professionally, she uses the alias IORI for her doujin circle, where she releases digital image collections that achieve moderate sales success.

Physically, she stands 170 cm tall with measurements of 81-56-75 cm (C cup). She has straight black hair styled in twin tails that extend past her hips, red eyes, and a pale complexion. Her everyday attire consists of practical jeans, T-shirts, and sweaters, though she occasionally wears latex, fishnet clothing, or bikinis in private.

Stoic and taciturn, she communicates minimally and displays limited facial expressions, though coworkers effectively interpret her unspoken cues. Pragmatic behaviors define her—she undresses to her underwear in the office when overheated, indifferent to male colleagues' presence, and frequently naps during meetings or work hours, reinforcing a phlegmatic demeanor. While generally disinterested in men and lacking sexual experience, she privately identifies as a pervert with a fetish for smells. She demonstrates loyalty to president Nene and colleague Kisara among the staff.

Regarding expertise, she is the only team member to have played an eroge to completion, skipping dialogue to study coloring techniques. She excels at technical aspects like shading but struggles to depict erotic elements such as bodily fluids (sweat, semen), sensual textures, or provocative compositions.
