In ".hack//Infection", Kite's friend Orca invites him to play "The World". In the first dungeon they visit, they encounter a girl in white, Aura, being chased by a humanoid monster. Aura tries to entrust Orca with an item called "the Book of Twilight", but the monster attacks him, crashing "The World"'s servers. Kite's player discovers that Yasuhiko, Orca's player, has fallen comatose after the attack, and resolves to discover the cause. Kite meets BlackRose, who takes him to a cathedral where they are attacked by a headless swordsman. The legendary player Balmung appears and defeats it, but the monster revives itself as a Data Bug. The Book of Twilight then activates, altering Kite's character data and giving him the Twilight Bracelet. He uses its Data Drain to correct the swordsman's code, allowing Balmung to kill it. Balmung accuses Kite of causing the viral infection spreading through the game, and leaves. Kite and BlackRose decide to cooperate to help the coma victims. After investigating a number of leads, Kite and BlackRose track down Skeith, the creature that put Orca into a coma. They defeat Skeith. The remnants of Skeith attracts a much larger enemy named Cubia, which defeats Kite and his party. Helba then drives Cubia away.
