Inexplicably dropped into a vast new world, the trio is greeted by Kurousagi, who explains that they have been given a once-in-a-lifetime chance to participate in special high-stakes games using their abilities. In order to take part, however, they must first join a community. Learning that Kurousagi's community "No Names" has lost its official status and bountiful land due to their defeat at the hands of a demon lord, the group sets off to help reclaim their new home's dignity, eager to protect its residents and explore the excitement that Little Garden has to offer.
