Fortunately, Kazuya and Rikuto seem to be rather close together. That's not exactly difficult- File City's big, but not that big- but it makes things easier for you.
After all, while the city's residents are sort of used to the idea of DigiDestined, you don't think using Birdramon to get around would be a good decision. If only because it seems like such a small thing to use Digivolution on, when Biyomon might need her energy later.
You hope she won't, but you're trapped in a dome and the Dark Masters are free. Things were never really going to be simple here.
Still, Kazuya and Rikuto are in locations pretty close to each other, so that's where you're going next. Both to see what they're up to, and to inform them that Maki has woken up, even if you're not sure if she'll be able to retain consciousness long enough to talk to them. If she's woken up on her own, by this point, someone else waking her up shouldn't be that much of a problem.
You run into Rikuto first. From what you can tell, he seems to be wandering. "Are you trying to get somewhere?" You ask as you approach.
"O-oh, Sora. I was just... seeing what this town has in it. It's a pretty impressive place."
"You should have seen it when we first got here." Back when everything wasn't covered up by an air of despair.
Biyomon nods, as much as she can when she's fluttering about. "Yeah! There were lights everywhere, and Digimon going just about every way, and nobody gave us odd looks or anything! It's still pretty great, but..."
Rikuto nods. "I suppose that would be better. But given that this is a world under the rule of the Dark Masters, the fact that any civilization could survive as this city has is something that the ones who had a hand in it should be proud of."
"...Are you going to actually tell Maki this?" You ask, curious. "Because she woke up a little while ago, if you wanted to go do that."
There's probably better ways to make an announcement like that, but you can't really think of them at the moment, so this is what you're going with.
"She's awake?" This is probably the most interest you've heard behind Rikuto's words, ever. You nod, and then he's gone, his dot blinking as it returns to the house.
Well. That's one down.
Just one more to go.
Kazuya, meanwhile, is at a restaurant, talking to a Centarumon. You have exactly zero context for any of this, but it sounds like they're sharing recipes or something, and you're not sure he'd respond well to any sort of disturbance.
Not that this stops you. After all, this is an important message that you have to deliver, at least in the context that this is Maki's friend, who cares about her, and who's probably been missing her a lot for the past four years. You know that you wouldn't be really okay with one of your friends vanishing to another world forever. Let alone without any sort of warning.
"Oh, there you are!" You call, waving as you approach. "I've been looking for you."
Kazuya glances at the Centarumon. "Sorry, this is probably something important." The Champion waves it off, and for a moment you wonder whether Kazuya being a DigiDestined has anything to do with that. He turns back to you. "Is something wrong?"
You shake your head. "It's sort of the opposite, actually. Maki woke up a while ago, and I thought someone should tell you about this in person." Versus Haruka's habit of two word Digivice messages that they might not fully understand, depending on how much they've kept up with learning Digicode. Assuming they ever bothered to learn, beyond the most important stuff.
"That... I see." And, suddenly, he's quieter than you thought he was able to be, if he weren't actually trying.
He might be thinking things through. He doesn't always do that, even if his more brash moments are still fairly rare, and it's as good a reason as any for why he's gone suddenly silent.
[ ] Does he want to go see her?
[ ] What is he thinking about?
[ ] What was he doing earlier?
[ ] Whatever it is, it's not your problem. You should head back now.
