"Well..." You think back, about all the adventures you've ever been on, the friends you've ever made, all of the ways that life and the good things you've found have gone up in flames, and sometimes those flames are entirely literal. "How about I tell you about what happened when I first became a DigiDestined?"
A crowd of little Digimon gathers around you, already enraptured by the promise of a story you have yet to even begin. "Tell us, tell us, da'gya~!" Upamon chants, and the rest of them are quick to join in.
"A-all right, calm down!" You laugh, and they quickly settle down. The power of storytime compels all, it seems. "So. It was... a long time ago for me, and an even longer time ago for you, when a strange egg came out of my parents' computer. It hatched into Nyokimon, who digivolved into Yokomon, and I... hadn't thought much of it, at first." To be fair, you had just been a kid at the time. "But a device came out of the computer, too, and using it, I was able to find other people like me, and two who would be like me eventually, but..." Honestly, thinking about it, it was probably a good thing that Tai and Kari didn't yet have their Digivices.
If they had, you wouldn't have put it past them to follow Maki to the Digital World, probably without even realizing what they were doing. And with how sick they both got after that... You aren't sure you would have ever seen them again.
"They... would be?" Chibimon repeated. "They weren't yet?"
"No, Tai and Kari wouldn't get Digivices for a while after. But that didn't mean they weren't involved, or anything. Somehow, they'd managed to get an egg of their own, which hatched into a Botamon. Within a day, Botamon had Digivolved into Koromon into Agumon."
"Ke-to?" Ketomon just sounds confused. You glance at Biyomon for a translation.
"He's asking if that's healthy. I don't think it is." You agree with her.
"Yeah, it probably isn't. Anyway, Kari, being three years old, decided that now was the time to try and hitch a ride on the back of a dinosaur. This was... concerning, for a lot of reasons, so I decided to call the first number I could see on a list of DigiDestined phone numbers, before following after them. Daigo Nishijima agreed to help me, and on the way, he met up with Maki Himekawa."
"Oh, I've heard about her!" Chibimon speaks up, his voice filled with excitement. "She has a dragon!"
You have no idea whether any of her partners' Digivolved forms look like dragons or not. You're just going to take his word for it.
"Well. She didn't have a Digimon with her at the moment." Technically, but you aren't going to go into the details surrounding her partnership to that Agumon when you don't know most of them herself. "But with their help, we were able to convince the Agumon that maybe it wouldn't be a good idea to run around Nerima setting things on fire." Okay. So it was mostly Daigo. That's not the point. "Yokomon even became Biyomon in the process. And... that's when something else appeared in the sky. A portal of some kind. And a Parrotmon stepped out."
"What's a Parrotmon?" Minomon asked.
"It's a big, green bird," Biyomon explains. "That one was mean." You can't even bring yourself to disagree.
"This Parrotmon... was not a fan of the Sovereigns," You state, quietly. "And, as a result, he wasn't a fan of the DigiDestined, either. In order to fight him, Biyomon became Birdramon and Agumon became Greymon. Individually, they didn't stand a chance against such a powerful Digimon, but together they could... well, they could do something, but..." Honestly, you aren't sure you could call what happened a victory.
"Y-yeah, we kinda broke a bridge..." Biyomon laughs, as if it were just a minor mishap instead of a massive amount of property damage that is still considered the worst terrorist attack in a decade. "Nobody really... they didn't like that..."
"They really didn't." You're not sure you could make this any more of an understatement.

[ ] See if you can't get away with ending the story here. Sure, the Digimon might get upset, but...
