Fireworks

打ち上げ花火、下から見るか？横から見るか？

In the seaside town of Moshimo, middle-schooler Norimichi Shimada and his friends argue over whether fireworks look round or flat from the side. When classmate Nazuna Oikawa, about to be moved away after her mother's remarriage, asks Norimichi to run away with her, he finds a glowing crystal ball she pulled from the sea that can rewind time. Each time he throws it, the day resets, and Norimichi gets another chance to change how things turn out with Nazuna.
