Prior events
During the first night of the Duelist Kingdom tournament, Katsuya Jonouchi, Yugi Mutou, Hiroto Honda, Ryo Bakura and Mai Kujaku were woken by the sound of a helicopter landing on the island. They all went over the helicopter and discovered Seto Kaiba had piloted it.

Yugi went over to Kaiba and gave him his Deck, which he had recovered from the Ventriloquist of the Dead. As Kaiba was about to leave, Jonouchi stopped him and refused to let him leave, reminding him of what he did during Death-T. Kaiba said he had almost forgotten Jonouchi was there too and mocked the level of the Duelist Kingdom tournament on seeing that Jonouchi was a participant. As Yugi and Honda restrained Jonouchi, he threatened to Duel Kaiba. Kaiba accepted, but warned Jonouchi that he would damage his ego.

Jonouchi tried directing Kaiba to a Battle Box, but Kaiba insisted that they use his Duel Disks prototypes instead. Kaiba explained that the rules would be similar to the Standard Duel Monsters rules, but the concept of the field would be different.
