In 2015, a fire destroyed most of The World's game data. CC Corp quickly began work on a replacement, splicing together the remaining data from The World with another game they were working on to form The World R:2. The plot focuses on Haseo, a newbie Adept Rogue in The World R:2. On his first day playing the game, he is PKed, but gets rescued by the mysterious Ovan, who tells him that he's special, and that he needs to become stronger. The beginning of the series focuses on Ovan's interaction with Haseo, as well as the rivalry between the members of Ovan's guild Twilight Brigade, and the huge guild TaN run by the player Naobi. It later follows Haseo's hunt for the elusive PK "Tri-Edge" and shows what happened to Haseo in the eight months prior to his appearance in .hack//G.U. Rebirth.
