Touzai President Ohara brings the Culture Department to a famous sushi establishment managed by Gingorou. Yamaoka criticizes the preparation quality and challenges Gingorou to compare his skills elsewhere. The group visits a hidden restaurant where Gingorou and the owner, Tomi, prepare sushi using identical ingredients. During a blind taste test, Tomi's creation is declared superior, irritating Gingorou. Yamaoka utilizes a hospital scanner to demonstrate the difference in rice compactness between the two chefs. The narrative reveals that Tomi is actually the renowned chef Tomijirou, who abandoned his previous restaurant to find joy in cooking for regular customers he considers friends.
