"Digimon: monsters who are born in the digital world. Although they're made up of data, they can also cry, laugh, and fight like we do. They're our important friends! Let's gather up as many teammates as we can! Come along with us in our adventure through this world"

Weeks later, the missing children who were transported to Digital world, returned to the human world and to their families with the help of DATS (Digimon Data Squad/Digital Accident Tactics Squad), DATS organized a rescue operation and scoured their officers throughout the Digital world, retrieving and rescuing the missing children that were in the Digital world. But when retrieving some of these children along with them, they carried a digivice and a small digimon that followed them to the human world. Due to these digimon partnering up and attaching themselves with these human children, DATS was forced to organize a special unit called the Tamer Union in the human world. The purpose of this union is to keep track of all digimon and their partners but it also allowed DATS to use the power of these children and their digimon partners in the human world, when recovering and fighting digimon that invaded or accidentally transported into human world. A few of these children and their digimon were even offered jobs and positions at DATS, becuase of their talent and ability, allowing them to enter and return to the Digital world and aid DATS in keeping the peace between the human and Digital World. These children were either working directly from headquarters or put in or formed factions and armies called Guilds, operating independently for the good or bad of the Digital world.
