1x7 - Mitsuboshi Colors

Yui and Kotoha have an awkward conversation while waiting for Sat-chan to arrive, after which the girls go around collecting trash. Later, the girls investigate a peculiar smell and wind up collecting stinky gingko nuts. With the arrival of Halloween, the Colors decide to play a Zombie Game in which Yui must prevent Kotoha and Sat-chan from filling the park with zombies.
