Obsessed with their rather ordinary classmate Ken Kirio, high school students Aimi Miyoshi and Nami Sometani form a peculiar friendship. Every time the girls hang out, they talk about Kirio and fantasize about interacting with the boy they usually just observe from afar. Aimi and Nami are mostly satisfied with the status quo, but they occasionally cannot help but be jealous of those who get to be near their crush—though this still rarely leads them to approach him directly.

Kei Asai lives in the oceanside city of Sakurada—a town where the inhabitants are born with strange abilities. On the school rooftop one day, he meets Misora Haruki, an apathetic girl with the power to reset anything around her up to three days prior. While no one knows when she has reset, not even Haruki, Kei can retain everything before the reset thanks to his own ability: photographic memory. After they successfully help someone by combining their powers, they join the Service Club to aid others in their town. However, their club becomes involved with and begins completing missions for the mysterious Administration Bureau—an organization that focuses on managing the abilities in Sakurada and manipulating the town's events for their own ends. They may find out that there are more things at work in Sakurada than the machinations of the uncanny organization.
