10th grader Yugi spent most of his time alone playing games...until he solved the Millennium Puzzle, a mysterious Egyptian artifact! Possessed by the puzzle, Yugi becomes Yu-Gi-Oh, the King of Games, and challenges evildoers to the Shadow Games...weird games with high stakes and high risks! These graphic novels contain new stories not seen in the anime, including the origin of Yugi and his friends!

Out of the sands of Egypt, the mystic Shadi has come to test Yugi's powers... because there can be only one King of Games. With the Millennium Scales and the Millennium Key, Shadi summons deadly illusions which will give Yugi his greatest challenge yet--and if he loses, his best friends will die! Then, Yugi's classmate Hanasaki takes his infatuation with superheroes too far; Yugi and his friends discover the hidden characters in digital keychain pets; and Yugi meets Mokuba, Kaiba's brother, for a high-stakes game of "Capsule Monster Chess!"
