The sports festival arrives and the group participates in a variety of events; Ui wins a sprint, Hina wins the 100m dash, Tsumugi struggles through an obstacle course and Ibuki demonstrates target archery. After a relaxing lunch with Senka and the Nakatsugawas, Kazuma and Ui prepare for the Hikonan Race. Alongside Hina and Koyori, the gang rush to consume thirty bowls of shiruko, catch ten freshwater eels, and continue to the finish in a random costume. Koyori skillfully makes her way into the lead wearing a wedding gown but trips on the dress, spraining her ankle. Kazuma, wearing a tuxedo, catches up to Koyori and failing to convince her to forfeit, picks her up in his arms and carries her to the finish, allowing her to place her first. Back at the hospital, Gengorou and Keita watch on television as Koyori proclaims to them that she has fulfilled her promise.
