The staff and cast from the first film reprised their roles, including production by A-1 Pictures and direction by Ayako Kōno, with character designs by Kento Toya and music by Yuki Kajiura. It was released on October 22, 2022. Plot 
In December 2022, the two lead guilds ALS and DKB, along with a few other players, defeat the 4th floor boss. The two guilds are somewhat at odds with each other over how to complete the game. After, main characters Asuna and Kirito along with side character Argo discuss a New Year's party planned by the two guilds. Asuna and Kirito go into the dungeon below the 5th floor's main town, where Asuna overhears two other players have contrived a plan to destroy the two guilds; the plan includes the guild ALS walking out of the party to kill the 5th floor raid boss, where it had otherwise been a joint effort. Kirito and Asuna later discuss the negative impact that ALS killing the raid boss would have on the effort to finish the game and then confront the leader of ALS, Kibao, who acknowledges the plan's existence. He reasons that the 5th floor boss has a powerful item that would give his guild the advantage in clearing the floors, but that he was forced into the plan by a faction within his guild. He gives a mixed blessing to Kirito, Asuna, and any other group who attempts and succeeds in killing the raid boss before his guild attempts to kill it. Kirito and Asuna gather a few members for their raid but fail to recruit Mito who is still disappointed by her actions in the previous film. Kirito, Asuna, and their raid group enter the dungeon and kill the monsters on the way to the raid boss. They discuss strategy before sending Kirito and Argo to scout the raid boss' room, only to start the fight by accident. The fight initially involves the boss' arms and legs attacking the players when the players step on lines on the ground. Shortly, the rest of the raid joins the group but set off the same attacks unwittingly. They eventually do enough damage to the raid boss where it exposes a crest, known to be a weakness, before the head hides itself. When the group attempts to retreat, the head comes out of the ground and seizes Asuna, who is freed by the surprise appearance of Mito. Then the crest begins appearing at random locations on the arms and legs of the raid boss; after a number of attacks on the crest, the raid boss materializes as a golem with the crest on his face. They subsequently destroy the golem and retrieve the rare item. While the rest of their party leaves to the 6th floor, Asuna and Kirito confront the now-arrived guild ALS. Kirito provides two conditions for providing the item, neither of which the guild then agrees to, but otherwise the guild peacefully departs. Later, on New Year's Eve on the 5th floor, Kirito and Asuna are ambushed by another player. They briefly scuffle and then the unnamed player disappears, wherein Kirito and Asuna realize the existence of a group or guild dedicated to killing other players. The film concludes with the two enjoying fireworks. Voice cast

Richard Eisenbeis of the Anime News Network gave the film a 'C+' rating, praising the world-building, production, and soundtrack, but criticizing its over-reliance to the same tropes presented in its predecessor, making the film "both more predictable and less emotionally powerful." Writing for The Guardian, Phil Hoad gave the film two out of five stars, praising its action sequences and animation, but criticizing its plot, noting "there is precious little ambition here beyond what feels like a clunky and redundant transposition of the videogaming experience." Meanwhile, Nick Valdez of Comic Book Resources gave it a positive review, praising its production and characters, but noted that the film is for longtime viewers and fans of the Sword Art Online franchise.
