This movie takes place in Kyoto, Kumi is a college student who moved there in order to take over the candy store inherited from her late grandmother. The house itself was accompanying the candy store was supposed to be unoccupied, but there Kumi then met three girls (Harami, Mai, and K) and a talking dog. The four of them were warrior heroines who got reincarnated from their fantasy world into the real world. One day, the former demon king, who messed up her reincarnation and is now in the form of an elementary school student, appeared and ask, "Will you please collect the demon king fragments together with me?" This to me is like an reverse isekai since fictional characters are being reincarnated in the real world.
