is the second main spin-off of the Yu-Gi-Oh! franchise. The series aired in Japan between April 2, 2008 and March 30, 2011, following the conclusion of the previous series, Yu-Gi-Oh! GX.The story focuses around characters playing a card game called Duel Monsters. This series introduces Synchro Monsters to the Yu-Gi-Oh! Trading Card Game. A new method of dueling exists where motorcycle-like vehicles called D-Wheels (Duel Runners in the English version) are used, and the duelists engage in games called Riding Duels (Turbo Duels in the English version).[2] The show is set in the distant future, where the upper class population live in Neo Domino City (New Domino City in the English version) and the lower class in a remote island where Domino's sewage is transported, Satellite. Yusei Fudo, the 18-year-old protagonist, lives in Satellite and makes it his objective to reach his rival Jack Atlas, who lives in Neo Domino. The series focuses on the five Signers, people embodied with a mark of one of the legendary Five Dragons who serve an ancient deity called the Crimson Dragon, their conflict with the Dark Signers, and the Three Emperors of Iliaster.
