character: kotegawa_yui. A full body, front-view shot depicts a stunningly beautiful high school girl, kotegawa_yui, standing in her room on the second floor of a traditional summer estate at night. She is captured in a "mikaeri bijin" pose, glancing back toward a full-length mirror with a panicked expression. Her exceptionally long hair, reaching 2 meters and flowing dynamically upward and outward despite the lack of wind, is mostly black with 10% turning light blue. She wears a white furisode kimono for adulthood ceremonies with blue overlapping collars and snow patterns, secured by a white fukuro-obi tied in a bunko knot and a white obi-himo. A 2-meter-long white veil covers her head, obscuring her face and flowing with her hair. She has pink lipstick, a snowflake hair ornament, and a single engagement ring on her left ring finger. The room is set in a summer night atmosphere, with the dark summer greenery visible through the open sliding doors, contrasting her wintery attire. The lighting is dim, provided by indoor lamps, casting soft shadows across the tatami floor.
