Chigusa Fukasawa, a first-year student at Minamigaoka High School, serves as the youngest member of the photography and art club. Having joined club activities before his official enrollment, he navigates the frustration of being excluded from the typical newcomer treatment. His playful, teasing nature shines through frequent bickering with senior Kurumi Kawai, though his friendliness disarms most tensions. Standing at 173 cm, his androgynous features and lighthearted charm make him popular among female classmates.

Outside school, Chigusa works part-time at his father’s café alongside clubmate Yuito Aoi. He delights in photographing girls and affectionately assigns nicknames to seniors—calling Asagi Kazeno "Asapyon" and Kurumi Kawai "Kurumi-chi." Throughout the series, his fearless yet charming demeanor fuels lively interactions, particularly with Hitomi Tsukishiro, as he bonds with fellow club members. Despite his seamless integration, he occasionally resents not being seen as a true newcomer due to his early club involvement. In the story’s final act, he joins others in bidding farewell to Hitomi, acknowledging her growth and the indelible mark of their shared journey.

Chigusa’s surname, Fukasawa, merges the characters for "deep" and "marsh," while his given name, Chigusa, stems from "thousand" and "grass." Born on August 2, his zodiac sign is Leo.
