A global card game descends and collapses the world order, where truth only exists within the bounds of cards. The ultimate goal of all players is to defeat their opponents and become the supreme Card Lord. Liam Moore, who was abused by his family, accidentally obtains the King Yama Legendary Card left behind by his father from the game's beta test. With this mythic Legendary Card, he defeats countless powerful opponents and clears every dangerous, eerie dungeon.
