The End of a Miraculous Summer

One morning during summer vacation, Natsuki and her friends gather in front of Takasaki Station and set off for a beach in Niigata Prefecture. During the journey, Natsuki and Miori's classmate, Honjo Serika, bond over their shared love of music. Despite being swept up in Serika's unique pace, Natsuki's circle of friends expands. Upon arriving at the seaside town, the group enjoys swimming, a BBQ, and fireworks. It's the sparkling summer day that Natsuki had always dreamed of.
