The two girls escape with Dennis as the duelist armies engage.

This episode contains example of:
- Foreshadowing: His dialogue shows that actually know what the Xyz dimension is and what's going on.
- Mook Horror Show: See No-Sell below.
- No-Sell: While fighting Obelisk Force members, they activate their monster abilities which afflicts effect damage to their opponent. It's been established that characters from different dimensions can somehow make the damage real; in this case the effect damage was in the form of a flamethrower. While grinning at first, the members become shocked when Yuya is hit full-on with the fire and gets up with the air of being shoved slightly and looking annoyed. This starts freaking them out and when they do it again, Yuya treats it with complete indifference, even brushing his shoulder off!! At this point, the members are sweating buckets, not helped when Yuya smiles at them eerily.
- Slasher Smile: A lot of characters display a lot of these in this episode from the Obelisk Force to Berserker Yuya and interestingly, Dennis.
- Unstoppable Rage: Berserker Yuya is brutally pissed off compared to his first appearance.
- The Worf Effect: Dennis in his duel against Selena.
- Worf Had the Flu: It also helped in his defeat that his Deck suddenly decided to troll him and give him cards he couldn't use for his strategy, partly because he was trying to dissuade her from thinking he was an Xyz remnant. And Dennis wasn't playing seriously the whole time. He also was about to reveal a face down card against the last attack, but someone distracted him and he didn't make it in time.
