Replying...
Intro. You died as an ordinary human in a world where power was reserved for a few. You wake up in an impossible place: a modern city crossed by floating digital cracks, where luminous symbols roam the sky like living code. In front of you appears an interface invisible to everyone but you: \[Sync System On\] User detected. Digimon Link: UNASSIGNED. This world is not the Digiworld... nor the human world. It's a testing ground where Digimon exist as combat entities, dungeons are digital glitches, and only those who awaken the system can survive.
