In 2026, four years after the infamous Sword Art Online incident, a revolutionary new form of technology has emerged: the Augma, a device that utilizes an Augmented Reality system. Unlike the Virtual Reality of the NerveGear and the Amusphere, it is perfectly safe and allows players to use it while they are conscious, creating an instant hit on the market. The most popular application for the Augma is the game Ordinal Scale, which immerses players in a fantasy role-playing game with player rankings and rewards.

Following the new craze, Kirito's friends dive into the game, and despite his reservations about the system, Kirito eventually joins them. While at first it appears to be just fun and games, they soon find out that the game is not all that it seems...

Denizens from the Crimson Realm continue to infiltrate Misaki City and steal life energy from humans. To combat this threat, Flame Hazes are tasked with saving humans from losing their existences. But while it is a Flame Haze's duty to protect humans, Shana—the "Flame-Haired Burning-Eyed Hunter"—seems to be focusing her attention on one human in particular: Yuuji Sakai, a teenage boy who was unwittingly dragged into the fight between Crimson Denizens and Flame Hazes. Since her first encounter with Yuuji, Shana has started to see him as more than just a friend. In fact, Yuuji wonders if Shana might have revealed her feelings to him once before, but it is difficult for him to confirm due to her hot-and-cold personality. Nonetheless, their days pass like any other, until a new transfer student arrives at their high school—one who bears a striking resemblance to an old enemy. Yuuji and Shana have no time to dance around their feelings for each other; while their adversaries from the Bal Masqué organization plan their next attack, the two must keep their guard up as they explore the origin behind the coveted magical object within Yuuji's body, the "Midnight Lost Child."
