Sword Art Online: Alicization - War of Underworld 2nd Season

The War of Underworld reaches its final stage as players from the real world flood the servers and turn the battlefield into chaos. Asuna and her allies fight to protect the Human Empire while their numbers steadily fall, and Alice races toward the World's End Altar with Gabriel Miller relentlessly pursuing her. At Rath, those outside the simulation struggle to repair Kirito's damaged fluctlight and restore his consciousness before every remaining chance disappears. With casualties mounting and resistance close to collapse, the bonds Kirito formed both inside and outside this world become the last force that may reach him. The outcome now carries lives on both sides of the boundary between reality and Underworld.
