Sword Art Online: Alicization

Kirito, Eugeo, and Alice. Six months have passed since the two disciples and an Integrity Knight brought down the pontifex, Administrator. With the fighting over, Alice has been living in her hometown of Rulid Village. Beside her is Kirito, who has not only lost his arm and soul, but also his dear friend. As Alice devotes herself to looking after Kirito, she too has lost the will to fight she once had as a knight. Nevertheless, the time for the final stress test – one which will engulf the entire Underworld with tragedy – draws relentlessly closer. Meanwhile, in the deepest areas of the Dark Territory, the Dark God Vecta has resurrected, as if to have waited for this very moment. Leading an army of dark forces, they begin their invasion into the human empire in hopes of attaining the Priestess of Light. The human empire force led by the Integrity Knight Bercouli prepares for a war of an unimaginable scale against the army of the Dark Territory. Even then, Alice is nowhere to be seen, nor the two heroes that saved the realm...

The final load test... The war between the Human Empire and the Dark Territory has engulfed Underworld entirely. The battle has shifted course with the Dark Territory army led by Gabriel, who seeks to capture Alice, the Priestess of Light, against Asuna and the Human Empire forces fighting to save Underworld. As Kirito's consciousness remains buried in a deep sleep, Gabriel, standing in as the Dark God Vecta, has recruited thousands of American players to log in to Underworld to annihilate the Human Empire forces. Meanwhile, Asuna, Sinon, and Leafa have joined the battle utilizing three super-accounts of the deities of the Underworld. As the Goddess of Creation Stacia Asuna fights alongside the Human Empire forces to take on the American players in a vicious combat. Sinon, who has gained the super-account for the Sun Goddess Solus, is in pursuit of Gabriel, who has abducted Alice, while Leafa arrives to Underworld with the super-account Earth Goddess Terraria. But that is not all... The impassioned speech by Lisbeth has convinced many ALO players to join the fight with the Human Empire despite the risks. With this great war, not only Underworld's continued existence, but the bottom-up artificial intelligence, the ultimate AI, and even the future of mankind is at stake. Though he has yet to awaken, only one man holds the fate of this world: the Black Swordsman.

In the near future, a Virtual Reality Massive Multiplayer Online Role-Playing Game (VRMMORPG) called Sword Art Online has been released where players control their avatars with their bodies using a piece of technology called Nerve Gear. One day, players discover they cannot log out, as the game creator is holding them captive unless they reach the 100th floor of the game's tower and defeat the final boss. However, if they die in the game, they die in real life. Their struggle for survival starts now...

One year after the SAO incident, Kirito is approached by Seijiro Kikuoka from Japan's Ministry of Internal Affairs and Communications Department "VR Division" with a rather peculiar request. That was an investigation on the "Death Gun" incident that occurred in the gun and steel filled VRMMO called Gun Gale Online (GGO). "Players who are shot by a mysterious avatar with a jet black gun lose their lives even in the real world..." Failing to turn down Kikuoka's bizarre request, Kirito logs in to GGO even though he is not completely convinced that the virtual world could physically affect the real world. Kirito wanders in an unfamiliar world in order to gain any clues about the "Death Gun." Then, a female sniper named Sinon who owns a gigantic "Hecate II" rifle extends Kirito a helping hand. With Sinon's help, Kirito decides to enter the "Bullet of Bullets," a large tournament to choose the most powerful gunner within the realm of GGO, in hopes to become the target of the "Death Gun" and make direct contact with the mysterious avatar.
