Non Eguchi is a high school student within Kaoru's friend circle. She stands 159 cm tall with a pale, slim figure and measurements of 98-54-89 cm, including a J-cup bust. Her hair, shifting between white, violet, or light lilac, appears in varied styles like curtained, shoulder-length, spiky bangs, twin braids, or twin tails. She has tareme-shaped eyes in green or cyan.

Personality-wise, Non is quietly kind yet mischievous and shy, often taciturn but possessing a perverted side. Her hobbies include searching for cute underwear and gaming. She harbors a secret curiosity about sex and frequently feels troubled or intrigued by adult shops.

As a member of the rhythmic gymnastics club, she excels with the ribbon but struggles with clubs. This leads her to accept unconventional training from classmate Kazuya, finding his methods peculiar yet following them despite reservations. Elements like bondage and cow cosplay occasionally surface in her activities or interests, sometimes accompanied by guilt.

Her attire is diverse, including school uniforms, leotards, bikinis, miniskirts, thigh-high stockings, knee-high socks, and Chinese dresses. She accessorizes with bells, kemonomimi headbands, and ribbon ties.

Within the dormitory setting, she serves as one of the female classmates targeted by Kazuya in his quest for sexual conquests.
