Yuri Chōno, the protagonist Tsubasa Sonokawa's childhood friend, manages their school's boys' basketball team. A wrist injury sidelines her, compelling her to recruit Tsubasa as a temporary replacement. Yuri dates basketball club president Hachiya, a relationship established early on. She actively engages in club activities, collaborating with Tsubasa during new student recruitment drives and observing social nuances, like teammate Yuuma Toba's "opposite effect" on attracting female members. Later, Yuri proposes team initiatives such as organizing a dormitory training camp and coordinating a welcome party for new recruits, demonstrating her continued dedication to team management. Her interactions remain consistently supportive, particularly towards Tsubasa, within her established functional and relational narrative role.
