A family has just moved to a small town with a somewhat rural feel. Their new home is rumored to be a place where mysterious things happen. The family's child, "Yume," has loved the classic folktale "Momotaro" ever since it was read to them as a baby. But one day, Yume begins to question the traditional elements of the story.  As Yume starts to customize the tale of Momotaro, these changes lead to encounters with gods and goddesses. This triggers a series of events that transports Yume into an alternate world filled with fantastical elements, all while maintaining a connection to the real world. Thus begins a fantasy story that moves between the world of fairy tales and reality, where Yume's journey through the folklore she once loved opens doors to new adventures and magical realms.
