In Sakurada, a town where nearly half the residents possess unique abilities, ranging from entering a cat's mind to rewinding time, a group called Kanrikyoku oversees these powers. Asai Kei and Haruki Misora, members of the Houshi club, carry out missions for Kanrikyoku. Misora can reset the world by three days, erasing all related events and memories. Kei, in contrast, holds the gift of perfect recollection. Together, they tackle challenges set forth by the Kanrikyoku by leveraging their complementary abilities.
