Sword Art Online: Alicization - War of Underworld is an action, adventure, and fantasy TV anime produced by A-1 Pictures, adapted from the light novel series by Reki Kawahara. Directed by Manabu Ono with series composition by Yukito Kizawa, this arc plunges viewers into an all-out war within the Underworld, where Asuna Yuuki and Alice Zuberg must rise to face overwhelming odds. With its expansive world-building, high-stakes battles, and a cast of compelling characters including Bercouli and Iskahn, War of Underworld delivers the most epic confrontation in the SAO franchise—a must-watch for fans of fantasy action anime.

The Underworld — a vast digital realm where human souls are cultivated through generations — has long maintained an uneasy boundary between the Human Empire and the Dark Territory. Alice Zuberg, once a proud Integrity Knight who stood at the front lines of battle, now lives a quiet life in her home village, tending to someone dear who has been left broken in both body and spirit. Yet peace proves fleeting. From the depths of the Dark Territory, an ancient and malevolent divine power stirs, marshaling a massive army with its sights set on the Human Empire and the one known as the Priestess of Light. Integrity Knight Bercouli rallies the human forces to stand against an invasion of unprecedented scale. But as the storm gathers on the horizon, the heroes who once saved this world are nowhere to be found — and the fate of the Underworld hangs in the balance.
