Plot

Three children, Sakamaki Izayoi, Kudō Asuka, and Kasukabe Yō, live dull lives because they possess unmatched psychic powers. One day, they receive an envelope that transports them to Little Garden, a place of supernatural powers called "Gifts." There, the residents use Gifts to play high-stakes games known as Gift Games in order to earn wealth and prestige for their communities. So, the three children join the fallen "No Name" community and resolve to help it regain its prosperity. As they learn more about Little Garden, they decide to overthrow the tyrannical Demon Lords in control.
