Rikka refuses to remove her eyepatch, which causes her to lack depth perception. To help her play despite this visual limitation, Yūta attempts to train her in volleyball. The training is intended to compensate for her inability to judge distance accurately while playing the sport. This effort focuses on adapting her skills to manage the challenges posed by her refusal to take off the eyepatch during gameplay.
