Upon Sumire Soma's urging, Kei meets Misora Haruki, a quiet, withdrawn girl who can reset the world up to three days in the past. Thanks to his ability, Kei can remember the time Misora has reset, and thus Sumire suggests that Kei becomes the companion of Haruki to help her use her abilities for good leading to them becoming part of the Service Club—a club that accomplishes tasks given to them.
