Cultural Festival!!.With the culture festival underway, the girls tour the school in order to advertise the bike derby. As the students place bets on which rider they think she'll win, Tazuko places a large bet on Raimu, who ends up crashing at the start line, leaving Hane, Onsa, and Rin to continue the race. Raimu soon gets back up and starts catching up to the others as they approach the final lap, leading to a photo finish. As Rin is announced as the winner, a friend of Hane's younger sister Yume shows interest in enrolling in the school.
