Rumors have circulated that a mysterious character will intrude into the fighting game "Fighters Kingdom" and take away the player who lost the game. Kiyoshiro, who was just addicted to the game, vows to never play such a terrifying game. However, Kotaro was excited to play the game and was taken away as rumored!
Hiro and the others meet with Professor Bokomon and Bakumon, who tell them the criminals are a Digimon brother and sister. The sister, Kinkakumon, loves to break into games and go wild. Ginkakumon is the younger brother of Kinkakumon. He turns defeated opponents into liquor. They were kidnapping the defeated players as a "booty" and planned to turn them into liquor.
In order to save Kotaro, Kiyoshiro plays the game. After his impressive 20 wins, Jellymon jumps into the game to challenge Kinkakumon with Kiyoshiro's help. Unfortunately, the Digimon siblings prove to be too powerful for Jellymon.
When Kinkakumon comes after Kiyoshiro, he uses his digivice, but goes into integer overflow and passes out afterward. Jellymon begs him to wake up as Kinkakumon is baring down on her. Kiyoshiro wakes up determined, which allows Jellymon to evolve to Teslajellymon. Teslajellymon defeats Kinkakumon.
Due to his sister's defeat, Ginkakumon must return all of the defeated players. Kotaro wakes up in his room wondering what had happened.
Ginkakumon is told he doesn't have to make booze, they will buy it here, and Hiro offers him his dad's stash. Kinkakumon said her interest was in battles saying she would like to battle Jellymon once again.
