49

Don Thousand and Vector enact their plan, using Mr. Heartland to spread one million "Fake Numbers" throughout the Earth. The Barian World and Earth begin to merge as a result, with Kaito taking up Yuma's mantle and Dueling Heartland. Meanwhile, Durbe has returned Nasch to the Barian World's throne, with Merag at his side, much to Vector's surprise and horror. (Source: Yu-Gi-Oh! Wiki)
