While waiting for the preliminary round to begin, Kirito reveals his gender after an embarrassing incident with Sinon in the changing room, and this creates a rift between them.

Season 2 - Episode 11 - Aired 9/13/2014
After hearing that Kirito had killed people in SAO, Sinon asks him how he was able to overcome the memories of the people he killed, but Kirito reveals that he didn't overcome them, instead accepting the weight of them, since it was all he could do to atone for his actions. Then, while thinking about how Death Gun was able to stop the heart of players by shooting them in the game, Kirito realizes that Death Gun did not shoot him with the pistol, but with the sniper instead. Based on this, Kirito deduces that Death Gun had to make preparations in real life to be able to kill the players with his pistol, and that he could've seen players putting their real-life details in the General Governor's Office since it was an open space and the terminals did not offer much privacy. Kirito then brings up the idea that Death Gun could have used his mantle to spy on other players without being noticed. After some thinking, Kirito realizes that Death Gun was actually two people: one shoots the player in-game, the other kills the player in real life by injecting them with a lethal drug. Meanwhile, Kikuoka Seijiro logs onto ALO as Chrysheight under Asuna's request and, after Yui reveals all the information on the incident that she had gathered, Chrysheight explains the situation to Asuna and the others.

#14 - Phantom Bullet

The battle between Death Gun and Kirito begins as the former unleashes a deadly barrage of strikes that greatly weakens Kirito. While they are fighting, Kirito has a flashback to the meeting before the Laughing Coffin raid in Sword Art Online, recalling a strikingly similar player with the same red eyes as Death Gun. Kirito deduces that Death Gun is really the infamous, "Red Eyed," Xaxa, the second in command of Laughing Coffin. As Xaxa goes for the final blow, Sinon creates the illusion of a direction line using her experience in the game alone, causing Xaxa to cloak to avoid it. However, Kirito pulls out his sidearm and fires it at Xaxa, stopping the cloaking process and rendering him vulnerable. Using the willpower and strength he possessed in Sword Art Online, Kirito defeats Xaxa, cutting in clean in half. Before he dies, Xaxa reassures Kirito that their battle is not over.

After giving his best wishes to the others, Kirito accepts the challenge but is unable to overcome Akihiko's absolute defense and intimate understanding of the game's mechanics. As Akihiko readies the finishing blow, Asuna overcomes her paralysis and takes the hit instead, losing all her HP and disappearing as a result. Distraught by Asuna's death, Kirito loses the will to fight and receives a fatal stab from Akihiko.

As they arrive at the Western Mountain, Kirito advises Liz to hide as he fights the dragon. However, she ignores his advice when she comes out when she thinks the dragon is almost defeated. The dragon blows her into a deep pit and Kirito jumps in to save her. While they both survive, they can't get out of the pit and are forced to sleep there for the night. Liz asks Kirito to hold her hand while they sleep, which brings her to realize that she can feel another person's warmth even though they are just data. She also realizes that she has feelings for him. The next morning, Kirito discovers that the mineral they are seeking, a Crystallite Ingot, is under the snow as the hole is the dragon's nest.

She also mentions that all players' real bodies must be currently being treated in hospitals and their condition cannot be kept indefinetly, thus fleeing to live by themselves inside the game is out of question.

Eventually, both Kirito and Sinon have made it into the finals. While waiting for Kirito, Sinon begins to feel he is just like her.

However, as Sinon takes a sniping position, she is suddenly shot with a stun bullet. Death Gun, who is actually Sterben, appears and proclaims that he is going to kill her.
