Mark of the Monkey, Part 1 / The Man with the Mark of the Monkey.The Dark Signers show up to taunt the Signers following Yusei's duel with Roman. Devack introduces himself and reveals he is in possession of Ancient Fairy Dragon and challenges Luna to come get it. Roman announces that their duels will take place at the four "stars of destiny". Whilst chasing after them, Jack discovers that one of the Dark Signers is Carly, who tells him to find her if he wants to know what happened. Back at Martha's house, the children are blaming themselves for her sacrifice, but Yusei promises the children he will be able to bring everyone back after defeating the Dark Signers, even though he is uncertain if that will actually happen. Mina discusses the whereabouts of the four control unit locations, and reveals that Goodwin received the legendary dragons from Professor Fudo, and put them into circulation where they eventually came across their current owners. Yusei decides to face Kalin, Jack decides to go confront Carly, Akiza heads towards Misty with Mina, and Luna, Leo and Trudge head towards where Devack is. Whilst on the way there, Luna gets contacted by Kuribon and is transported to the World of Duel Monster Spirits. When Leo goes looking for her, he encounters Devack. Whilst he is uninterested in dueling someone who isn't a Signer, Leo challenges him anyway, hoping to defeat him so Luna won't have to. Yusei returns and watches the match with Trudge, as Devack gains a lead with his monkey deck.
