The novelization is divided into four sections: The first section details Yuugi solving the Millennium Puzzle. The second section recounts Yuugi's initial meeting with Seto Kaiba as depicted in the manga. The third section covers the second encounter with Kaiba at Kaiba Land. It skips over many areas that do not involve the card game. The fourth section is an original story exclusive to the novel. Two weeks after Yuugi's battle with Kaiba in Kaiba Land, Yuugi receives a call from Kaiba, who instructs him to meet for a Duel on the top floor of KaibaCorp. Yuugi agrees, and when the duel starts, they employ a special variation known as the "Bingo Rule," which prohibits the use of a specific card in each player's deck. Kaiba appears to be himself, but plays a different trump card, the "Automatic Giant." Mokuba stumbles upon them and informs Yuugi that Kaiba has not yet awakened from his catatonic state. It turns out that the Kaiba Yuugi is playing against is a Cyber Kaiba, controlled by the KaibaCorp computer and utilizing all of Kaiba's memories. Yuugi defeats the "Automatic Giant" and Kaiba with a card called "The Unknown Egg."
