Sword Art Online the Movie: Progressive - Scherzo of Deep Night

In December 2022, two lead guilds ALS and DKB defeat the 4th floor boss, causing conflict over completing the game. Asuna, Kirito, and side character Argo discuss a New Year's party planned by the two guilds, where they overhear a plan to destroy the guilds by killing the 5th floor raid boss. The two friends confront the leader of ALS, Kibaou, who acknowledges the plan but claims he was forced into it by his guild. Kirito and Asuna gather allies to thwart the plan, and after a series of missteps, they successfully defeat the raid boss, retrieving a rare item that gives them an advantage in clearing the floors.
