There, the girls compete with Hibiki Hagyū, who gets lost easily, and her childhood friend Ren Ekoda, who she has a crush on. Facing various obstacles on every space, both Hanako and Hibiki's teams end up stuck in an infinite loop and are put in a competition to determine who ends up in last place. With the final match being a quiz, Hanako causes her team to end up last in order to save Hibari from revealing her personal secrets.
