Lost One (未帰還者) is the euphemistic term used by the System Administrators of The World to refer to players in comas. Although this term is used to a lesser extent in the first series, this page only lists the Lost Ones from .hack//G.U. that were in a coma for more than a day, where the term is virtually synonymous with the victims of AIDA-PCs or Tri-Edge.

- Lost Ones were called Unreturners in the Japanese version of .hack. Some old US episode listings use the title "Unreturner" instead of "Lost One".
