Sakurada is a town where residents are born with unique abilities. Kei Asai, a resident with photographic memory, meets Misora Haruki, a girl with the power to reset the past up to three days. Haruki's resets can't be predicted, but Asai retains memories of the previous timeline. They join the Service Club, initially to assist townspeople, but eventually become involved with the Administration Bureau, which oversees abilities in Sakurada and orchestrates town events.
