のんのんびより 沖縄へ行くことになった

When Suguru Koshigaya takes the grand prize in a department store raffle, four plane tickets, the Asahigaoka kids get a trip to Okinawa dropped in their laps: Renge Miyauchi, sisters Komari and Natsumi Koshigaya, and Hotaru Ichijou. The younger ones rehearse sitting on an airplane and stock up at the convenience store, while Renge spends the evening before departure quietly saying goodbye to the countryside she has never left. This OVA bridges the TV seasons and sets up the later Vacation film.
