The seventy-fifth boss lair has been found, and SAO's top four players have been recalled back from their treasured honeymoons. On this memorial day, bear witness to the final moments of their trial as heroes of Sword Art Online.
A year and a half has passed since Sword Art Online was beaten, and the survivors have been doing their best to reintegrate into society. With the launch of the Augma, a new way to bring the real world and the virtual has been created, such as the game Ordinal Scale. But for some, like Koharu and her friends, it can be the thing that wipes away their memories of Aincrad, both precious and unwanted. If it means saving Asuna's memories and fighting an old friend, she and Jaymes will join Kirito's crusade.
