This is a world based on cards. Whether it's powerful extraordinary creatures, divine weapons containing divine power, or even things like hurricanes, lightning, and flames themselves, they can all be sealed by cards. Those who have mastered the ability to control these cards are called Summoners. Yu Chu, who traveled through time with a certain card game system, faced the fate of being sacrificed by the villain as soon as he opened his eyes, and the only thing that could save him was the system's gift of a single card draw opportunity. But it doesn't matter, everything about a true Summoner is inevitable, even card drawing can be created! Single draw miracle!
