Yu-Gi-Oh!: Saving the World Through Card Games

Mo You transmigrates to a Yu-Gi-Oh! world occupied by demons and unexpectedly obtains a Card System. He sets out to save the world of Yu-Gi-Oh!, but one person alone is no match for billions of enemies corrupted by the power of darkness.

Kaiba, Jonouchi, and the others also become loyal subordinates of Lord Mo.

Things look grim. But with the help of the God of the Planes, Mo You builds a bridge between souls and uses the game as his call to action, summoning tens of thousands of duelists from Earth to fight the demons together.
