During a sunny afternoon at the mall, Suguru Koshigaya stumbles upon winning the lottery"s top award—four tickets to Okinawa! Overwhelmed with wonder and thrill, the Asahigaoka girls set about preparing for their getaway. They rehearse flying techniques, purchase travel gear at the corner shop, and handle every detail ahead of time so their Okinawan adventure can be fully enjoyed. Renge Miyauchi, who has never left Asahigaoka before, feels the shift as she imagines how her worldview might transform. With each passing day leading up to departure, the group promises themselves a memorable journey. They agree to share hoping the experience will deepen their bonds and broaden horizons beyond what they knew.
