The World of Guns
A year has passed since SAO was cleared. Summoned by Kikuoka of the Virtual Division at the Ministry of Internal Affairs and Communications, Kazuto learns of a series of bizarre murders linked to the popular VR game, Gun Gale Online (GGO).
Armed with a large sniper rifle, the young girl Sinon is making a name for herself as the No. 1 sniper in GGO. When her squadron ambushes another squadron, she succeeds in taking out her first target.
Memories of Blood
In real life Sinon is a high school student named Shino Asada. Because of an incident from her childhood, Shino is traumatized by the sight of guns. What kind of incident was it...?
Kikuoka recruits Kirito to investigate GGO. To lure Death Gun into targeting him, Kirito hopes to enter Bullet of Bullets (BoB), a tournament to decide the most powerful gunman in GGO. But he soon loses his way and catches sight of Sinon.
Guns and Swords
Kirito registers for the BoB tournament. He will be competing in the same block as Sinon, and there's a chance that they'll clash in the final if they both advance. They promise each other to go all-out if they do meet.
Bullet of Bullets
Certain that both Death Gun and the man in the ragged cloak are competing in the BoB final, Kirito approaches Sinon beforehand about exchanging information, and begins to investigate the other players.
Attacked from behind by Death Gun, Sinon has her back to the wall. Kirito barely manages to rescue Sinon and attempts to flee with her, but they are pursued by Death Gun, and find themselves on the brink of disaster.
What It Means To Be Strong
After escaping from Death Gun, Kirito and Sinon lay low in a desert cave. There, Kirito speculates on how Death Gun murdered the other players. Kirito deduces that some condition must be met in order to kill a player in the real world.
Bullet of a Phantom
BoB has reached its last stage, and the field of survivors has been narrowed down to Kirito, Sinon, Death Gun, and Yamikaze, the previous tournament's runner-up. Kirito finds himself confronting Death Gun at last, but...
The End of the Journey
Several days have gone by since Yuuki vanished from Asuna's sight and stopped logging in to ALO. Asuna asks Siune why Yuuki disappeared. Rather than explaining in detail, Siune answers that "Yuuki probably doesn't want to see you again."
The Dream Begins
As a tester for the world's first medical Full-Dive device, the Medicuboid, Yuuki has been diving into virtual worlds from the hospital. Terminally ill and unable to leave her sterile hospital room, she longs to go to school one more time.
