The novel adaptation is divided into four parts: the first section details Yuugi unlocking the Millennium Puzzle, the second section recounts Yuugi's initial clash with Seto Kaiba as depicted in the manga, and the third section narrates their rematch at Kaiba Land, focusing mainly on the card game aspects. The fourth section introduces an exclusive storyline not found in the manga, set two weeks after Yuugi's previous encounter with Kaiba. In this original plotline, Kaiba challenges Yuugi to a Duel at the pinnacle of KaibaCorp, implementing a unique gameplay rule known as the 'Bingo Rule.' During the Duel, Kaiba surprises Yuugi with a new card, the 'Automatic Giant.' However, a revelation occurs when Mokuba interrupts the match to disclose that Kaiba remains in a comatose state. It is unveiled that the opponent Yuugi faces is actually a Cyber Kaiba, controlled by KaibaCorp's computer, utilizing Kaiba's memories. Ultimately, Yuugi triumphs over the 'Automatic Giant' and the cybernetic version of Kaiba using a card named 'The Unknown Egg.'
