From the introduction: Welcome to the Directory Continent, home to Digital City, humanity’s bastion from the cruel mercies of Boss digimon who seek to wipe them out from the face of the world. Malicious digimon warlords who nurture a burning hatred towards humanity, and take advantage of digimon turned feral by a terrible infection to create great hordes to attack the Digital City. Luckily they can always depend on their Guard Tamers and their Digimon Partners who work tirelessly to ensure both the safety of humanity and the destruction of these malicious monsters before they can enact their wicked schemes.
