Changes

At the harbor, [[Zuzu Boyle|Zuzu]] and [[Sora Perse|Sora]] are Dueling; Sora controlling "[[Fluffal Bear (anime)|Fluffal Bear]]" while Zuzu controls "[[Aria the Melodious Diva (anime)|Aria the Melodious Diva]]" and "[[Sonata the Melodious Diva (anime)|Sonata the Melodious Diva]]". She activates "[[Polymerization (anime)|Polymerization]]" from her hand, fusing "Aria" and "Sonata," and she [[Summon chant|chants]], "Enchanting melodies bloom in splendid glory and play for us a new harmony! Fusion Summon!" But instead of a monster, an error message pops up on her [[Duel Disk]], and Zuzu panics, frantically asking why it didn't Summon her [[Fusion Monster]]. Sora asks if she remembered to put the monster into her [[Extra Deck]], and Zuzu reacts in confusion. Sora patiently explains that he's told her a dozen times that Fusion Monsters go in the Extra Deck, not the [[Main Deck]]. Shamefully admitting that that's right, Zuzu removes her Deck from her Duel Disk and sees "[[Schuberta the Melodious Maestra (anime)|Schuberta the Melodious Maestra]]". Behind a nearby warehouse, [[Yuto|the masked Duelist]] is eavesdropping. Later, Sora points out that Zuzu had front-row seats for two of his Duels, and she should have been able to figure Fusion Summoning out form that. He could have beaten the Duelists without Fusion Summoning, but did so anyway so that Zuzu could learn. Zuzu apologizes, and Sora jumps down from the container he was sitting on, commenting that he bets that she was thinking about ''him'' again, wasn't she? Zuzu blushes and looks away, and Sora proclaims that he knew it; that's why Zuzu's been Dueling so absent-mindedly. He asks who the Duelist is, but Zuzu doesn't know, so instead Sora asks to confirm that it was the second time that they'd met. Zuzu admits that the first time had been here as well, when he'd stepped in to save her from [[Sylvio Sawatari|Sylvio]], telling her that he didn't want her to get hurt. Sora asks if that's how the masked Duelist stole Zuzu's heart, prompting an embarrassed response from Zuzu. Fortunately for her, Sora doesn't press the issue further, admitting that he's excited himself, as the Duelist seems like a pretty interesting guy. If [[Julia Krystal|Julia]] hadn't butted in, he might have been able to Duel the masked Duelist. Taking a large bite out of a chocolate bar, he comments that that was really disappointing. Zuzu protests that Sora can't Duel him, as he's dangerous. She remembers the Summoning of "[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion Xyz Dragon]]" and wonders why the Duelist was able to create actual shockwaves outside of an Action Field, and why he told her that he didn't want her to get hurt anymore.

The masked Duelist remembers standing in a [[Heartland City (ARC-V)|destroyed cityscape]], claiming that he didn't want to hurt anyone anymore. He hears something up to his right above him looking up to see a [[Yugo|white-suited Duelist]] sitting astride a [[Duel Runner]]. The Duel Runner projects its screen and Card Zones, and the Dark Duelist activates his own Duel Disk. The White Rider ramps off the building and charges towards the Dark Duelist. An explosion of dust rises up, the Dark Duelist emerging and Summoning his "Dark Rebellion Xyz Dragon" (in the dub, he further tells his dragon to prepare to battle). Swerving away from the Dark Duelist, the White Rider Summons his own monster, a [[Clear Wing Synchro Dragon (anime)|a glowing white dragon]], and both [[Dragon]]s charge and clash. [[Shay Obsidian|The Duelist in the blue coat]] who had been surveying the [[Leo Corporation]] runs up with [[The Resistance|four of his fellows]], and the White Rider grits his teeth in annoyance before fleeing. The second Duelist asks the Dark Duelist where [[Lulu Obsidian|Lulu]] is, but the Dark Duelist just shakes his head. The second Duelist curses (in the dub, he wonders where she could be).
