Yuya’s anger toward Yuri, who had defeated Yusho, reaches its peak. A Duel between Yuya and Yuri then begins. With the “Smile World” card his father left behind for him in hand, Yuya fearlessly resolved to fight Yuri. However, when the dragons on the Field resonate, the darkness within Yuya and Yuto’s feelings overflow and agonize them.
This episode contains the following tropes:
- Ax-Crazy/Large Ham:Yuri: "IT'S HERE, IT'S HERE, IT'S HERE!!!"
- Casting a Shadow: As Yuya demands that his father be released, a dark pulse emits from him, knocking back Reiji.
- Darkest Hour: Serena has been absorbed, starting up Arc-V. As Yuya and Yuri duel, no matter the outcome Zarc will be revived.
- Evil Feels Good: For Yuri, unlike his counterparts, he enjoys whenever one of the Four Dimension Dragons are summoned giving Zarc more power, although he's already influenced by Zarc up this point. Leo's parenting style definitely doesn't help.
- Heroic Resolve: Yuya refuses to give into Zarc's influence this episode because he remembers what happened the last time that happened and he wants to follow his father's advice.Yuya: As long as Dad is watching over me, I won't lose!
- Heroic Sacrifice: When Yuya tells Yuto that his plan to defeat Yuri involves summoning Dark Rebellion. Yuya is uncomfortable as he remembers what happened the last time all four dragons were summoned. Yuto tells him to do it as he's sure even if he's absorbed into the Darkness, Yuya can save him.
- Heroic Willpower: Yuya throughout the episode continually tries to remain in control and is mostly successful because of his willpower.
- Laughing Mad: Yuri when Yuya was about to activate Dark Rebellion's effect.
- Loophole Abuse: How Yuri would have finished off Yuya the same way Yusho was finished off, as lampshaded by Reira. Yuya defies this, however, with his Starlight Force Continuous Trap.
- Loved Ones Montage: After Yuya is forced to summon both Odd-Eyes and Dark Rebellion, assembling all four dimension dragons. He has one as he fights Zarc's influence to remain in control.
- Madness Mantra:
- Yuri excitedly exclaiming "IT'S HERE, IT'S HERE, IT'S HERE!!!".
- At the end of the episode, Yugo and Yuto both say they will become one.
- Mythology Gag: The episode's title doubles as a reference to a card with the same name.
Though the card doesn't appear in the episode, it had thematic relevance: drawing power from the shadows and paying a price, with the risk of losing everything you have. - Nightmare Face: Yuri shows a bunch of them throughout the episode.
- O.O.C. Is Serious Business: Yuri actually telling Yuya to give up is rather telling when before all he cared about was defeating his opponent.
- Powerful and Helpless: Despite being powerful Duelists, all an injured Reiji and Reira can do is watch helplessly as Yuya fends off Yuri while struggling to resist the darkness from consuming him.
- Rage Breaking Point: Yuya is royally pissed off at Yuri for carding and mocking Yusho.
- Ship Tease: As Yuya remembers everyone he wants to save, Yuzu is the longest and last image he sees.
- This Is Unforgivable!:Yuya: Unforgivable... You turned my dad into a card... RELEASE HIM!!!
- Unspoken Plan Guarantee: Yuya's strategy to defeat Yuri's Starve Venom and Clear Wing is revealed to Yuto. Unsurprisingly Yuri not only counters it but even takes Dark Rebellion.
- Wham Shot:
- Yuto disappearing in the darkness.
- Yuri taking Dark Rebellion Xyz Dragon.
- Serena disappearing in Arc-V.
- Xanatos Gambit: Conversed by Reira; according to Ray, Zarc's ressurection is imminent regardless of the outcome of Yuya and Yuri's Duel.
