In an alternate reality world that resembles Edo Period Japan, Luffy acts as a member of the police. This is made up of two adventures: in the first, Buggy makes trouble in the town; in the second, a mysterious girl named Vivi appears (aired after Episode 253). This special contains several cameos from characters throughout the entire series. A second pair of episodes were aired after episode 290, continuing this story, as part of the New Year's special.

The world of Duel Monsters is once again evolving with the development of a network called Link Vrains and a new summoning mechanic introduced as Link Summoning. By using this cyberspace, duelists can now create their own avatars and duel their way to glory within a virtual reality. However, much like the real world, the digital world is not free from war, conflict, and mysteries. Years ago, a hacker organization known as the Knights of Hanoi unleashed an attack on Link Vrains. Led by the anonymous Revolver, their aim was to annihilate the artificial intelligence program known as the Cyberse. After a failed attempt, one of their targets, Ignis, managed to escape and hide the Cyberse somewhere in the network. Five years later, high school student Yuusaku Fujiki encounters a strange artificial intelligence program while dueling in Link Vrains. Under the guise of his avatar named Playmaker, Yuusaku and his partner in crime, Shouichi Kusanagi, decide to join forces with the peculiar existence. As he seeks the truth behind a mysterious incident of the past, Yuusaku battles against the Knights of Hanoi and SOL Technologies in a race that might alter the fate of the world.

Ever since they encountered aliens on the moon, humanity's technology has developed by leaps and bounds. Half a century later, even though most have it easy, Robby Yaji and Hacchi Kita cannot seem to catch a break in this advanced society. Robby—a man perpetually struck by misfortune—owes large sums of money to debt collectors due to his poor investments in shady get-rich-quick schemes, and Hacchi finds it difficult to get over the boredom of his mundane life. The two end up on an adventure of a lifetime when loan shark boss Yang sends Hacchi to collect the money Robby owes. Rather than pay up, Robby blasts off into space and heads to Isekandar, a planet that supposedly brings happiness to anyone who visits. Seeing a chance for some much needed excitement, Hacchi tags along with Robby on this journey filled with alien encounters, giant robot battles, and all sorts of troublemaking—all the while avoiding Yang and his cronies who are desperately combing the universe to find them.
