Sword Art Online: Progressive, a retelling of the series’ Aincrad arc, was first published by author Reki Kawahara in 2012 and now spans eight volumes, with each volume generally covering a single floor in the Sword Art Online game, starting from Floor 1 in Aria of a Starless Night.
“Scherzo of Deep Night” is the title of the fourth volume’s storyline, which means we’ll be jumping ahead to Floor 5 of Sword Art Online when the new film premieres this fall in Japan.
It’s been just two months since they were trapped in the game of death that is Sword Art Online, and Kirito and Asuna continue their struggle at the vanguard of progress through the game.
