ข้อมูลอนิเมะSword Art Online II

Almost one year has passed since SAO has been cleared. Kazuto meets with Seijiro Kikuoka of the Ministry of Internal Affairs and Communications and learns of a strange incident that has taken place in the VRMMO “Gun Gale Online (GGO).”

Sinon is known as the best sniper in GGO, armed with the Hécate II sniper rifle. She, along with her squadron, attacks another squadron, successfully sniping the first target.

In real life, the player 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 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.

Barely managing to register for BoB in time, Kirito will be competing in Block F of the preliminary tournament. Sinon is also in Block F, and there's a chance that they'll clash in the final. They promise each other to go all-out if they do meet.

After witnessing Kirito’s fight to win his first preliminary match, a man clad in a ragged cloak asks him, "Are you the real deal?" It is then that Kirito and Sinon, having both advanced in the preliminary round, face off in the Block F final.

The man in the ragged cloak is an SAO survivor... This thought 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.

Kirito approaches Sinon about exchanging information and begins to investigate the other players. Meanwhile, the final round begins and a Battle Royale between 30 players is now underway on a massive field measuring 10 km in diameter.

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.
