Izayoi Sakamaki, Asuka Kudou, and You Kasukabe are unusually gifted individuals who feel unfulfilled by their ordinary lives. Their existence is transformed when they are the recipients of cryptic invitations, inviting them to enter the mysterious realm of Little Garden. Here, Kurousagi informs them that their psychic powers can be put to use in high-stakes games, but first they must become part of a community. Kurousagi guides them to "No Names," a group that has been rendered homeless after losing their status due to defeat by a demon lord. The trio is eager to help "No Names" recover their lost land and status, while also discovering the wonders of Little Garden.
