Kei Asai resides in Sakurada, an oceanside city where residents are born with peculiar abilities. One day on the school rooftop, he encounters Misora Haruki, an apathetic girl who possesses the power to reset anything around her to a state up to three days prior. While neither Haruki nor anyone else knows when a reset has occurred, Kei can retain all memories from before the reset due to his own ability: photographic memory. After successfully helping someone by combining their powers, they join the Service Club to assist others in their town. However, their club becomes involved with and begins completing missions for the mysterious Administration Bureau—an organization focused on managing abilities in Sakurada and manipulating the town's events for its own ends. They may discover that there are more forces at work in Sakurada than just the machinations of this uncanny organization.
