Sword Art Online: Alicization - War of Underworld

Six months after the battle against Administrator, Alice Zuberg has returned to Rulid Village and is caring for Kirito, who has been left profoundly damaged by what happened. With the immediate fighting over, Alice has also lost much of the resolve she once possessed as an Integrity Knight.

The pause cannot last. A final stress test capable of engulfing the entire Underworld approaches while the Dark God Vecta rises in the Dark Territory and leads an invasion toward the human empire. Integrity Knight Bercouli organizes the human forces for a war on an enormous scale, with the attackers seeking the Priestess of Light. Alice and Kirito, however, remain absent as the conflict begins to gather momentum.
