City

City (シティ Shiti) is a major city in the Yu-Gi-Oh! ARC-V anime, located in the Synchro Dimension. It is an alternate universe version of New Domino City from the ''Yu-Gi-Oh! 5D's'' anime.

History
City's society is competition based - the "winners" gain everything, and the "losers" lose everything. The top 1% of the population, known as Tops, is made up of the "winners". They control 99% of the city's wealth and reside in a magnificent cityscape build high above the slums of the city. The remaining 99% of City's population, referred to as Commons, is made up of the "losers", and resides in those slums. Its population is around 10,000,000. Despite both Commons and Tops being equal in social status on paper, in reality society and the system heavily discriminates against Commons. City is patrolled by Security and according to Yūgo is known to serve the interests of the Tops. Much like with Satellite, if a Common is found in Tops-exclusive areas without authorization, Duel Chasers will immediately be deployed to duel and arrest them. Despite the wide discrimination against Commons, it is possible for a Common to gain acceptance among Tops by virtue of becoming a winner, as this dimension's Jack Atlas as widely known to have risen from the slums after winning the Friendship Cup.

City also has separate lanes for Riding Duels, though its highways are also capable of erecting energy barriers to divert incoming traffic away from the dueling lanes so that the Riding Duelists can enter the dueling lanes more easily.

Some time before the start of the series, Yūri abducted Rin from the slums. In response, Clear Wing Synchro Dragon granted Yūgo the power to cross the dimensions, allowing him to chase after Yūri.

During the Maiami Championship, Yūgo and Yuzu Hīragi were transported to somewhere in Tops by Yuzu's bracelet. There, the two explained to each other their knowledge of the events that had transpired before they were discovered by Tops residents. This forced them to flee on Yūgo's D-Wheel only to be forced into a Riding Duel by Security.

City is introduced as the main Synchro Dimensional setting for the ARC-V series after the Maiami Championship in the Standard Dimension concluded with the formation of the Lancers. The group travelled to the Synchro Dimension's City to seek allies against the Fusion Dimension's Academia, but received a harsh welcome from the City's Security forces, turning into fugitives and eventually being forced to participate in the Friendship Cup by the Executive Council to prove their power and reliability as partners. The Lancers soon become players in a game of power between Security's chief Jean-Michel Roger, the Council and the Commons, with the threat of Academia present in the background.

During the semi-final match, the Academia launched a small-scale invasion. Despite Yūya and the Lancers' effort, Serena was sent back to Academia and Yuzu was captured by Roger. The City was soon driven into turmoil as Commons started rebelling against Tops, forcing Roger to uphold a marital law, turning the City into further chaos. To stop the chaos, Lancers split up to intervene: Yūya Dueled Jack in the final match, Tsukikage and Sora Shiun'in went to save Yuzu, Noboru Gongenzaka, Shingo Sawatari, and Shun Kurosaki prevented the Commons from their further advance, and Reiji faced against Roger. Yūya's Dueling earned attention and support from the whole residents of City who were watching, and eventually united them together the moment he won the match. Watching how much the City has changed from the Duel between Yūya and Jack led the Executive Council to resigned from their position and abolish the Tops and Commons social system, finally truly making the residents of City equal. Their celebration was cut short when Sora revealed Roger's plan who has recaptured Yuzu, prompting the remaining Lancers to rush to Public Security Bureau building where Reiji was Dueling Roger.

Technology
City retains D-Wheel technology, though they also use the Duel Disk technology common among the Duelists in ARC-V.
