trauma, her friend Kyōji Shinkawa convinced her to play Gun Gale Online. Known as Sinon ingame, her main weapon is the «PGM Ultima Ratio Hecate II» sniper rifle, which she earned after defeating a monster in a dungeon. Shortly before the Bullet of Bullets (BoB) tournament, Sinon encounters Kirito, deciding to help him after believing he is female due to his avatar. After Kirito's true gender was revealed, an angered Sinon attempts to leave him, but they meet again during the BoB. The two are confronted by Death Gun, who causes Sinon's PTSD to relapse when his weapon was revealed to be a Type 54 pistol, the same weapon she had used in the post office shooting. She is rescued by Kirito and the two escape, though she is afraid to attack Death Gun. With his help, Sinon overcomes her fear and the two defeat Death Gun. Afterwards, the two end the tournament as co-winners after Sinon kills them both with a «Gift Grenade». Upon exiting GGO, Shino is visited by Shinkawa, who congratulates her on winning the BoB. However, angry at Kirito, he attacks her with intentions of committing double suicide, and reveals himself to be one of Death Gun's creators. Shino manages to resist his attack and escape, but is stopped by Shinkawa before she could exit the house; Kirito arrives and fights Shinkawa, the latter eventually being knocked out by Shino throwing her stereo at him. After the Death Gun incident, Sinon seems to have gotten over her fear and is moving on from the incident, no longer vulnerable to her classmates' threats of using a gun on her. In Agil's café, Shino meets Asuna, Rika, and Sachie Osawa, a woman who had survived the post office incident, who convinces her that she had saved her and her daughter's life. Sinon eventually decides to play Alfheim Online with Kirito and his friends. In other media Sinon appears in the Sword Art Online video games. In Sword Art Online: Infinity Moment and Hollow Fragment, she is trapped in Sword Art Online as a result of a glitch while testing a full-dive machine known as the Medicuboid. In the sequel Sword Art Online: Lost Song, she becomes a playable character. Reception Critical commentary Richard Eisenbeis of Kotaku praised Sinon's role in Sword Art Online II, describing her as "easily the deepest character to come out of Sword Art Online".
