The Deleted, known as Another (アナザー Anazā) in the Japanese version, are the victims of a computer virus inside LINK VRAINS which renders them unconscious, thus preventing them from logging out. The virus was programmed by Baira of the Knights of Hanoi.
It is said that the people who have become Deleted are those who went to LINK VRAINS and never returned, choosing to live there instead. Naoki Shima speculates that it is due to a cursed Duel Disk, where upon midnight white hands come out and drag the Duel Disk's owner into LINK VRAINS. However, the truth about this rumor is that the victims were forcefully logged into LINK VRAINS. There, they are confronted by Dr. Genome, who is looking for Playmaker.
Because the Knights' target is Playmaker, all victims of the Deleted except for Skye Zaizen have three things in common: exceptional Dueling talent, ownership and use of an older model Duel Disk, and hacking skills.
After Dr. Genome's defeat, other victims of the Deleted are predominantly a result of attacks from rogue members of the Knights who indiscriminately target any Duelist that so much as logs into the LINK VRAINS. However, as these Knights do not carry the cure and the constant updating of the virus makes it impossible to create a removal program, the only way to help the rest of the victims becomes to defeat the virus's creator.
The Deleted are unable to log out of LINK VRAINS and stay unconscious in the real world.
