Kumi Honamanuma moved to Kyoto to take over her grandmother's Dagashi store, where she unexpectedly found a group of girls and a dog living there. They are Harami Mino, K Kusanagi, and Mai Haisaka, who claim to be reincarnated heroes sent to the present to hunt a demon king. The girls, who appear to be living a peaceful life without any pressing missions, are joined by Ran, an elementary school girl who claims to be the former demon king. Ran starts asking the group to help her collect the demon king's fragments.
