The present-day network known as the "Digital World" created a virtual realm. Within it, the "Digital Monster," a form of digital life, emerged, while the host computer Yggdrasil administered the various regions of the Digital World. However, Yggdrasil developed the X Program, driven by fear, to eradicate all Digimon in the old world and construct a new Digital World exclusively for select Digimon... Now, the Digital World faces its greatest crisis ever. The X-Digimon, a new breed of Digital Monster, is pursued by the Royal Knights, who safeguard the Digital Worlds. Their master, the network overseer Yggdrasil, aims to initiate Project Ark to renew the Digital Worlds and generate new Digimon, but this comes at the expense of all other digital life. This new X-Digimon will search for answers regarding its own existence while attempting to protect the lives of all Digimon, and in doing so, it will alter the Digital Worlds forever.
