Turn up the speakers and wave your glowsticks, because Aijo Rentaro's girlfriends are banding together to form an idol group for the school festival! No challenge is too big for the Rentaro family, but the girls have plenty to rehearse and there's not a lot of time left until the festival. There'll be drama, there'll be tears, and there's probably going to be an inordinate amount of cuddling involved. In any case, it's time to stan a hot new idol group, because the show must go on!
