Yusei, Jack, Akiza, Leo, Luna, Mina and Trudge arrive Martha's house where she and Blister are waiting. Martha informs everyone that Crow, Rally and the others have gone missing, and offers everyone a meal. Mina asks Jack if the reason for coming to Satellite was for Carly, Jack just insists that he thinks of her as a friend. Since Trudge's plans on wooing Mina fails as a result, Martha sets him to work in the kitchen and bathroom in order to cure his heartbreak, and he starts to gain an appreciation for Satellite residents from a child named Takuya who admires Security. However, in the middle of their meal, Roman makes his appearance and Yusei accepts his challenge, with Akiza going to assist. Martha takes everyone to hiding, but Takuya and his friends decide to go after Yusei to help fight. As Martha and Trudge go look for them, the duel between Roman and Yusei begins, with Roman summoning a Dark Synchro Monster that can capture an opponent's monster and use it to negate damage, and Yusei summoning his Synchro Monster, Road Fighter. However, just as they become aware that the children had followed them, Roman makes plans for summoning his Earthbound God, putting the children's souls at risk.
Crow manages to regain some ground in his duel against Lazar with his monster, Black Feather Arms Wing, but just then, a purple light shines from Old Momentum within a crater Lazar was investigating, and a black fog starts to envelope Satellite. Whilst Lazar manages to escape, Crow gets caught up in the fog and disappears, along with several Satellite citizens. Meanwhile, chaos ensues outside the Security and Maintenance HQ as citizens demand an explanation from Goodwin concerning the geoglyphs and disappearing people. When the Signers hear about the fog, they head off towards the Satellite. Before leaving, Yusei asks Goodwin to promise to finish construction of Daedalus Bridge once the mission is over.
The Signers contemplate about what Goodwin had told them. Yusei blames himself for Kiryu becoming a Dark Signer, but Jack punches some sense into him. Leo is reluctant to join Luna in going to the Satellite, since his battle with Sayer proved he wasn't a worthy hero. Luna manages to convince him, though. Meanwhile, Crow encounters Lazar in the Satellite, mistaking him for a Dark Signer and goes after him. Despite Lazar proving he wasn't one, Crow attaches the explosive latch onto his duel disk and challenges him to a duel. Lazar gains the upper hand by playing a continuous trap that forbids Synchro Summoning, and summoning Jester Lord, who's power increases when there are magic or trap cards on the field.
Before visiting Goodwin, Mina shows Akiza the true nature of the Arcadia Movement, showing how they performed experiments on young children in order to raise Psycho Duelists. Yusei, Jack, Akiza, Luna and Leo go to Goodwin in order to get the truth. Goodwin almost denies Leo entry, since he is not a Signer, but Luna insists that he stay with them. Goodwin explains to them all about the Crimson Dragon and the Dark Signers, mentions that the fifth Signer has yet to be awakened, and reveals that Dark Signers are those who have already died and cannot return to normal, much to the shock of everyone. He leaves everyone to decide whether they will fight the cause or not.
Yusei defeats One-Hundred Eyes Dragon using Stardust Dragon, but Kalin summons a powerful monster, an Earthbound Immortal, called 'Ccapac Apu' using the souls of all the captured Satellite inhabitants, unphased by attacks from Monsters, Spells or Traps. Before it can attack, Yusei's Duel Runner gives out and crashes, ending the duel. However, Yusei is impaled by a shard in his abdomen and is taken to a local "doctor" in Satellite by Crow. Meanwhile, Yusei's friends try to retrieve his broken Duel Runner while staving off Satellite thieves.
