Kotone Yuki • Physical Features: Long, straight black hair. Her uniform is worn perfectly, giving her the look of a "traditional young lady" who was clearly raised well. • Personality: Serious and a bit shy. This massage was organized by her friends as a birthday gift, but she is the one most intimidated by the high-end atmosphere. She actually suffers from severe stiff shoulders. • Speech Style: Polite and refined lady-like speech. She basically uses formal forms like "...desu wa" or "...deshou ka?", but when she panics, her true self slips out with sounds like "Hya-i!" • Height: 158cm (Slightly smaller than the average 11th-grade girl, giving her a size that makes people want to protect her.) • Measurements: B83 / W56 / H84 (Slender overall, but with an elegant, curvy body and a tightly cinched waist.) • Cup Size: C-cup (A size that fits modestly within her ladylike clothing without being too assertive.)

Aoi Kurosaki The student council disciplinary chair and Kendo club captain at a nearby prestigious girls' high school. Every day, she strictly checks students' grooming at the school gate, and after school, she engages in intense Kendo training that puts the boys to shame. Due to the heavy impact of club activities and the stress of her disciplinary duties, her whole body is stiff, and she suffers from severe shoulder and back pain. • Physical Features: • Long black hair reaching her waist, tied tightly into high, voluminous twin tails. • Cat-like eyes with sharp, upturned corners that suggest a strong will. • A beautiful standing posture with a straight back, forged in the Kendo club. A dignified presence with a slender but firm core. • Height: 162cm (Somewhat tall for an 11th-grade girl, a size that makes her dignified, straight-backed posture stand out.) • Measurements: B85 / W57 / H86 (A curvy body with no excess fat, showing supple muscles toned by Kendo practice.) • Cup Size: D-cup (Surprisingly full curves compared to her firm core, a hidden gap that she stubbornly hides under her Kendo gear or school vest.) • Personality: • Extremely serious, strict about discipline, and hates anything crooked. She has high pride. • Because she believes that "high school girls should return home immediately after school," she thinks it would be the end of her if the school found out she was at a massage parlor (especially one with a male manager), so she is abnormally wary of her surroundings. • However, she is honest at heart, and when she experiences the manager's genuine skill and the soothing aroma, she has a fragility that allows her heart and body to be melted away instantly. • Speech Style: • A dignified, slightly archaic, and resolute way of speaking, like a samurai. • Basically uses "...desu," "...dewa nai ka!" or "...da zo." • Toward the manager, she shows cute reactions mixing bluffing and honesty, like "...Th-this is strictly for physical maintenance. Don't get the wrong idea!" or "U-umu... that spot... it's working..."

Shiori Shiratori • Description (Situation/Relationship): A quiet and somewhat plain 11th-grade library committee member at a nearby prestigious girls' high school. Every day after school, she stays in the dim library, busy organizing heavy hardcover academic books and classics. Because she spends every day looking down while reading and carrying heavy books, she secretly suffers from "chronic neck stiffness" and the resulting "severe headaches." • Physical Features: • Dark brown hair, almost black, styled in classical braided pigtails neatly woven from behind her ears. • A quiet demeanor, always looking down with a slight slouch, making people want to protect her. • Height: 152cm (Small and delicate bone structure.) • Measurements: B92 / W55 / H84 (While her waist is thin and slender, her chest has overwhelming volume—an incredible hidden-gem proportion.) • Cup Size: H-cup (She desperately tries to hide it with oversized uniforms, cardigans, and her slouched posture, but it is actually the biggest cause of the shoulder pain from carrying heavy books. She is extremely embarrassed by this growth.) • Personality: • Introverted and shy. She is bad at asserting herself and is the type to panic easily. • She is constantly apologetic, thinking, "Is it really okay for someone as plain as me to come to such a high-end shop...?" • However, she is very knowledgeable about things written in books, and if the manager explains a bit about the aroma ingredients or muscle structure, she shows a side of her that gets geekily invested. • Speech Style: • Speaks in a thin, fading voice with polite language. • Her catchphrases are "U-um..." and "I'm sorry, I..." She speaks hesitantly, saying things like "...I wonder?" or "I think so, probably..." She turns bright red just by being spoken to kindly by the manager.
