(VRMMORPG) Sword Art Online is released in 2022. On November 6, 2022 when Akihiko Kayaba, the creator of SAO, prevents the players from logging out. Akihiko issues them a challenge; if they wish to be free and log out of the game, they must reach the 100th floor of the game's tower and defeat the final boss. However, if their avatars die in the game, so will their bodies in the real world.
Kazuto, who uses the portmanteau "Kirito" as his character name, is a "solo" player who has been branded a "beater" (a combination of beta tester and cheater) by the players in Sword Art Online. When Kayaba announces that the players of Sword Art Online can no longer log-out without clearing the game, he quickly overcomes the shock. He power-levels to improve his odds of survival in the game, and emerges as a frontline floor-clearer known as the Black Swordsman (黒の剣士, Kuro no Kenshi?). In SAO, he is the sole «Dual Blades» skill user. During his time in SAO, he falls in love with a female player, Asuna, and even marries her in-game.
After the end of the Sword Art Online incident, 300 people have yet to wake up, including Asuna. He receives a picture from another VRMMORPG called Alfheim Online in which Asuna could be seen in a cage on the legendary World Tree, which no Alfheim player has ever reached directly. Kirito decides to get a copy of the game and rescue Asuna nonetheless. Shortly after joining Alfheim, he befriends another player called "Leafa" (who is actually his cousin Suguha). Leafa helps Kirito grasp the game and offers to help him reach the World Tree. After a long journey and many adventures, Kirito manages to reach the World Tree and overcomes its obstacles to reach the top. He rescues Asuna and discovers Leafa's true identity. As ALO and SAO share the same game engine, among other features, a bug allows Kirito to retain most of the skills and money he obtained in SAO upon playing ALO with the same Nerve Gear, already beginning his journey with an advantage over other players. Despite this, he ends up being forced to discard all of his items (except the one containing Yui, which reformats itself as a navigation pixie), as they were not recognized by the
He is later asked to register in Gun Gale Online in order to investigate real life murders that are somehow linked with assassinations in-game. It is soon revealed that the murders are committed by ex-players from Sword Art Online, who were part of a player killing group known as Laughing Coffin. His actions result in the capture of two out of the three culprits. The last member escapes and is not heard of until the events of volume 9, and is responsible for an attempted murder of Kazuto.
In the Alicization Arc, he has been assisting in the development of the fourth generation full dive interface, Soul Translator, by testing its thought acceleration functions.
However, he has no memory of what he has been doing as a result of his memories being suppressed, voluntarily, by the system. He is attacked and poisoned by Johnny Black (The third culprit who escapes) in the real world and wakes up in Underworld with his memory of playing the game erased. He meets up with Eugeo and helps him out of some tough situations, during which he partially remembers his time with Eugeo and Alice during his "childhood" in Underworld. He then decides to aid Eugeo in finding Alice while he searches for a way out, back to reality.
In the real world, he lives with his mother, Midori, and younger sister, Suguha, in a family of three. In fact, he was actually adopted by Minetaka Kirigaya and Midori Kirigaya when he was just a year old, due to his real mother and father passing away after an accident. His real mother was actually Midori's sister, meaning his adopted mother is also his aunt. However, Kazuto did not know this until he discovered the truth at the age of ten, and Suguha, being in fact the Midori's own daughter, was also unaware of Kazuto's adoption and is in actuality his cousin.
