In 2026, a new machine called the Augma is developed to compete against the NerveGear and its successor, the Amusphere. A next-gen wearable device, the Augma doesn't have a full-dive function like its predecessors. Instead, it uses Augmented Reality (AR) to get players into the game. It is safe, user-friendly and lets users play while they are conscious, making it an instant hit on the market. The most popular game on the system is Ordinal Scale (aka: OS), an ARMMORPG developed exclusively for the Augma.
Asuna and the gang have already been playing OS for a while, by the time Kirito decides to join them. They're about to find out that Ordinal Scale isn't all fun and games...

Progressive - Aria of a Starless Night

One month after Kayaba Akihiko's game of death began, the death toll continues to rise, two thousand players having already lost their lives to the ultra-difficult VRMMO world of Sword Art Online. On the day of the strategy meeting to plan out the first-floor boss battle, Kirito, a solo player who vows to fight alone to get stronger, runs into a rare, high-level female player.

Progressive - Scherzo of Deep Night

Following on from the previous film, Sword Art Online: Progressive – Aria of a Starless Night, the main characters, including Kirito (voice of Yoshitsugo Matsuoka) and Asuna (voice of Haruka Tomatsu), have made it to the fifth floor of an on-line game where the players are trapped inside and are not only fighting for their lives in the game but also for their real lives beyond it. There are two main guilds battling each other for leadership status; rogue individuals trying to kill off players; and virtual monsters and ghosts to fight in the dungeons and catacombs. Consequently, Kirito and Asuna work together to organise a small group to outmanoeuvre the warring guilds, destroy the floor boss and level the playing field, giving each trapped individual an equal chance at survival. The only problem is that the game is adapting and intent on destroying them all. Will Kirito and Asuna succeed or will they perish in the process?
