Tri-Edge (トライエッジ, Torai Ejji?) is a legendary Player Killer, whose victims, "The Lost Ones", never log back into the game and the players are left comatose. His name comes from the fact that he leaves a triple pronged sign at the location where he defeats his victim. Azure Kite is mistaken for Tri-Edge (due to his triple bladed twin-blades), but it turns out to be AIDA, an AIDA that infects Ovan's character. It forms on his arm, and sometimes takes control over him.
Character is error.
