Kokoro Hasegawa

Height: 181 cm (5'11")

A young aspiring, hard-working fashion designer, first-year student at the Geika Institute of Fashion, and part-time model at "Bon Rouge". She has a shy, submissive, and meek personality, and is rather self-conscious about her height, though she became less bothered by it when she was scouted in high school.

Despite being talented as a model, Kokoro dislikes the nuances the job includes, but her feelings of debt towards her manager Igarashi and her lack of confidence prevents her from quitting. Upon befriending and working alongside Ikuto at Yanagida's studio, Kokoro gradually begins to be more courageous and challenging herself due his encouragement, though she is still prone to self-doubt and worries.

During the Geika Festival, Kokoro and Chiyuki make a bet with Igarashi to let her quit modeling if Kokoro wins first place in the competition, which she does. Following her period abroad to study in Paris, Kokoro returns to Japan to work for Toh's upcoming brand. Kokoro greatly values her relationship with Ikuto and comes to realize she has romantic feelings for him.
