"You have all been such fine helpers, children. And now, we have reached the last world." Balan said.
"Hmm… Looks like a blend of some old ruin and cyberspace." Sachiko said. "What the heck is this place supposed to signify?"
"It's a mix of two eras, so… Maybe someone is getting behind in the times." Akira said.
"Maybe. Still, though… Hard to believe this is really the last one." David said. "We've had a lot to bond over during our time here, and...now it's almost over."
"Yeah, it's actually kind of sad. But now we understand what you're going through, so our time here wasn't a complete waste. Balan bringing us here made us a lot stronger after all." Kasumi said.
"Not just stronger. We got to connect more like we should have." Eri said.
"Right, so don't worry about us. We can hold our own now. Let us handle protecting Tokyo in your stead. After all, it's our home too." Kita said.
"Damn right it is. No one is going to lay a finger on it while we're around!" Kazuma said.
"You can count on us to get things done when they matter the most." Ayase said.
David nods with affirmation. "Then come on, everyone. Let's tackle this last one together!"
The scene goes to a city that shows an old man, Bruce Stone, who is cleaning up the littering of a park. But no matter how many times he tries, the park ends up being dirty again, like he feels invisible to the populace. He morphs into a robotic creature that is capable of camouflage. However, despite this ability, he was soundly defeated.
"I just can't keep up with the young ones anymore, I guess. You kids have me beat." Bruce said.
"All because we banded together like a team. There's only so much one person can do on their own, after all." David said.
"I understand how it feels to be invisible. It's been on my mind for a while now." Ayase said. "But you're not really invisible if people see the work you're putting in. I'm pretty sure there's someone out there that does."
"Yes. And that leads to them taking responsibility for themselves. We'll never stop learning, and never stop growing." David said.
Bruce was soon cleaning up the trash again, but this time, the kids see the effort he puts in and help him out, making the park cleaner than it has ever been.
"I really like how this turned out. They all seem really happy now." Rankira said.
"Yeah. I'm glad we all got together for this one." David said as they saw a dark portal from the island they were in.
"Looks like Lance decided that he's done messing around." Naomi said.
"Yeah. All that's left now is one final battle. Let's hit him with everything we've got!" David said.
