S4 receive a request to produce this years Christmas festival. Yume and the others come up with ideas for the festival, which include erecting a giant Christmas tree in the town shopping district and performing a show for the shoppers. The idols from Venus Arc also decide to help. Ako overhears that M4 have decided to separate after the new year so that each member can pursue their own goals. Rola also receives an offer to make her world debut.
