Getting to experience the outside world, Yuuki’s days are more satisfactory than ever before. In ALO, the players have a barbecue and end up on a quest. In the real world, Asuna and the girls take a trip to Kyoto.
As a tester for the world’s first medical-use Full-Dive device, Yuuki has been diving into virtual worlds from the hospital. Unable to leave her hospital room, she longs to go to school again. Meanwhile, Asuna asks Kazuto for help.
A few days have passed since Yuuki suddenly disappeared from in front of Asuna, and she still hasn’t logged in to ALO. Later, Asuna meets Kazuto on the school roof, where he hands her a note and tells her Yuuki might be at the location written on it.
Asuna is asked to help the guild “Sleeping Knights,” which has decided to disband soon due to the members’ circumstances. Before they do, they want to defeat a Floor Boss with only their party, something usually done with 49 people.
Kirito is in dire straits. He is driven into a corner due to Death Gun's prowess not only as a gunman, but as a swordsman, too, and he is beginning to lose all strength. Meanwhile, Sinon desperately tries to figure out what she can do.
Attacked from behind by Death Gun, Sinon has her back to the wall. Death Gun's weapon is, oddly enough, the same gun that Sinon used to kill the bank robber. Death Gun tries to kill Sinon, stunned by flashbacks, in order to motivate Kirito.
The man in the ragged cloak reveals himself to be Death Gun, and announces that he'll be bringing on real-life death. Meanwhile, Kirito and Sinon decide to join forces, hoping to take Death Gun down before there are any more casualties.
The man in the ragged cloak is an SAO survivor and it consumes Kirito to the point that it worries Suguha. Meanwhile, Shino can't shake off her irritation towards Kirito, and she launches into a tirade, swearing that she'll defeat him.
Kikuoka has recruited irito to investigate GGO, and so he logs in. To lure Death Gun into targeting him, he hopes to enter Bullet of Bullets (BoB), a tournament to decide the most powerful gunman in GGO.
