Last month, the internet went down. Entirely, across the globe. An hour later, it was as if nothing had ever happened - Investigation into what happened is still ongoing, without a single hint as to what happened having been found. Your connection never died though. And through it, an egg emerged. Too bad the creature that hatched from it last week doesn't have any more idea what's going on than you do. It did hatch alongside an odd device though, the functions of which are almost all locked at the moment - something about fragmented data. For now it just shows some relatively meaningless data on the newly hatched digimon, and a map of the city.
...Sadly, you won't be having much time to get used to things. The digivice is acting up. And your new partner isn't feeling so good.
