Friendship Cup

Friendship Cup (フレンドシップカップ Furendoshippu Kappu) is a tournament held in the Synchro Dimension mentioned in the Yu-Gi-Oh! ARC-V. The tournament is said to have made Jack Atlas the current Duel King. It was created to promote harmony between the Tops and Commons after the Commons revolted when Chojiro Tokumatsu was arrested. However, some of the Commons, such as Crow Hogan, thinks that the tournament only serves as a show for Tops.

There appears to be a large amount of controversy regarding the motives of the tournament, due to Jack being viewed as a traitor by many of the Commons, a hero by the other part, and the Tops consider him to be one of them. According to Yūgo the purpose of the event is deciding who is worthy of challenging Jack to a Duel. Every year a participant is picked for an exhibition match, which in reality is meant to show the rest Jack's overwhelming strength, because of that Jack's opponent is called "The King's sacrifice".

There is a horrible conspiracy behind the tournament where losers are taken to an Underground Labor Facility and forced into servitude (though once there they can win their freedom by Dueling). However, the people of the City don't seem to find anything wrong with this as it's "natural" for the defeated to fall.

Requirements
Within the Underground Dueling Arena, defeating 10 people in a row allows one to participate in such tournament. Alternatively, one can also sign up by filling an application sheet, which apparently needs to be approved by​ Jean-Michel Roget, though Roget may also invite people he deems worthy himself.

Tournament
The Friendship Cup is conducted as a 16-player knock-out tournament. The participants are kept in a building owned by the Executive Council to keep Jean-Michel Roger and Security from interfering, although they are locked in. Matchups are determind on the spot with the remaining participants, with the chosen Duelists being released at that moment and led to the Duel Palace. The losers, however, are forced to leave the building and then sent to Underground Labor Facility. After the duel between Shun and Dennis, the rest of the tournament takes place in the City.
