Six months after the battle between the Dark Signers and the Signers, a large stone tablet falls (which is Machine Emperor Wisel Infinity's tablet) from space and lands on Earth, just outside of New Domino City. Whilst investigating it, Lazar encounters three people from Yliaster, who are Jakob (the leader), Lester (self-appointed sub-leader), and Primo (the lowest-ranking member). Lazar questions them about their intentions, but after being reminded by Primo that they were his leaders, and a brief outburst in which Primo points the tip of his sword at Lazar's neck, he quickly submits to the trio, and turns over the leadership of New Domino City to them. Then, Primo tells the other members of the trio that he was going to take his Machine Emperor out for a "test drive." A day later, Sector Security investigates a turbo duelist named Ghost, who is attacking Turbo Duelists, and "stealing" their Synchro Monsters, at night.
