An ordinary male named Lucifer traveled to the digital world and obtained two golden fingers. The first golden finger is called the Invasion of All Worlds System. The function of this system can help invade any world in the heavens and all the worlds. As long as the host takes over that world, it can transform the creatures in that room into Digimon and obey the orders of the array. The second golden finger is called the All Worlds Chat Group.
