Volume 02

Aincrad (アインクラッド, Ainkuraddo?) is the 1st book in the Sword Art Online Light Novel series, published on April 10, 2009.


Solo player Kirito, who had the luck-of-the-draw to once play the beta version of a new VMMORPG, is imprisoned along with 10,000 other players of «Sword Art Online» (SAO) inside of the game, unable to logout; the only way to live is to unlock all the levels of the game. Death in-game means death in the real world, due to the NerveGear-the console that simulates the in-game character controls by redirecting brain signals. Escaping the death game requires the defeat of the final boss on the top floor and two years later, out of the original 10,000 players at the start, only 6,000 remain and there are 26 floors left to clear.



A huge castle made of stone and steel floating in an endless sky. That was all this world was.

It took a various group of craftsmen one month to survey the place; the diameter of the base floor was about 10 kilometers — large enough to fit the entirety of Setagaya-ku within. Above, there were 100 floors stacking straight upwards; its sheer size was unbelievable. It was impossible to even guess how much data it consisted of.

Inside, there were a couple of large cities along with countless small scale towns and villages, forests and plains, and even lakes. Only one stairway linked each floor to another, and the stairways existed in dungeons where large numbers of monsters roamed; so discovering and getting through was no easy matter. However, once someone made a breakthrough and arrived at a city of the upper floor, the «Teleport Gates» there and of every cities in the lower floors would be connected making it possible for anyone to move freely through these levels.

With these conditions, the huge castle had been steadily conquered for two years. The current front line is the 74th Floor.

The name of the castle was «Aincrad», a world of battles with swords that continued floating and had engulfed approximately six thousand people. Otherwise known as... «Sword Art Online».

Chapter 1Edit

Kirito, after fighting a Level 82 «Lizardman Lord», recollects what happened two years ago.

Chapter 2Edit

Klein asks for Kirito's guidance after he realizes that Kirito was one of the one thousand participants of the «Sword Art Online Closed Beta». After Klein successfully defeats a «Frenzy Boar», he tries to log out because he ordered pizza. Failing to find the logout button, Kirito and Klein discuss the implications of the "unable to logout bug".

Chapter 3Edit

Without warning, they were both teleported to the central plaza of «Starting City». The GM Kayaba Akihiko informs them that the only way to logout is by clearing all one hundred floors of the floating city of «Aincrad», and that death in-game means death in real life.

Kirito, realizing that there will be shortage of monsters near «Starting City», urges Klein to leave the village along with him. Klein asks Kirito whether they can take his friends along. Kirito, unable to bear the heavy burden of Klein and his friends' lives, wordlessly disagrees. They separate after Klein decides to help his real life friends.

Chapter 4Edit

Almost a month into the game, 2,000 players have died. The remaining players are divided into four groups. Non-players, «The Army» members, wasters who later join «The Army», and guilds. Only a mere fraction are solo players.

Chapter 5Edit

Kirito successfully kills a super rare monster «Ragout Rabbit» and teleports to Algade to sell the «Ragout Meat». He later decided against selling the Meat after talking with the shop owner Agil and meeting Asuna the «Flash»; sub-leader of the guild known as the «Knights of the Blood». He agrees with her cooking the ingredient in her house in exchange of giving her half the meat. Asuna order her subordinates that she will be leaving for the day, displeasing her bodyguard: Kuradeel. He directs his anger to Kirito after realizing he is a «Beater» (a combination of a «Beta tester» and «Cheater»). Asuna, disgusted with Kuradeel's actions, orders him to leave. She ends the conflict by leaving with Kirito through the crowd.

Chapter 6Edit

Kirito journeys with Asuna to her home in the 61st floor to cook the «Ragout Meat». Upon arriving, Asuna prepares the meal with her maxed out cooking skill. After enjoying the gourmet meal with the taste synthesized by the «Taste Reproduction Engine», Asuna later persuades Kirito into forming a party with her.

Chapter 7Edit

An unhappy Kirito was waiting for the late arriving Asuna at their specified meeting place. Asuna, running away from her bodyguard Kuradeel, bumps into him while using a teleportation crystal. Kuradeel, who strongly disagrees of her recent actions tries to take her back to their guild headquarters. Kirito intervenes for Asuna’s sake and enters a 1-on-1 duel against Kuradeel. Kirito easily wins the match by breaking Kuradeel’s decorated two-hand sword. Kuradeel, enraged by his defeat, threatens to kill Kirito. Asuna orders Kuradeel to return to «Granzam» to prevent things from escalating any further. Asuna later apologizes to Kirito for the trouble.

Chapter 8Edit

Kirito and Asuna were discussing each other’s taste in clothing until Kirito noticed the movement of numerous flashing green cursors on his virtual scanner. With both of them hiding under Kirito’s coat, they hide themselves behind the trees as they watched the 12 players from the guild «The Army» march past. Asuna then informs Kirito about the change in behavior of «The Army». Both fear that «The Army» might try the suicidal task of challenging the yet to be discovered boss of the 74th Floor with no knowledge of the boss and with just 12 members. After the battalion moves past them, the two head into the Floor's Labyrinth.

Chapter 9Edit

The «Knights of the Blood» was known as the best guild in over a year; the leader of the guild, the «Man of Legend» Heathcliff, and the sub-leader Asuna the «Flash» were both renowned as two of the best warriors in Aincrad. Kirito thought about this as he was teaming up with Asuna against the common skeleton enemy: the «Demonic Servant»; both display their excellent teamwork with a skill known as «switching» against their common foe. As they map the dungeon, they soon come across the eerie looking door of the boss room. After a few minutes of hesitation, they peek inside and look for the dweller of the dark room; there their eyes met with «The Gleam Eyes», the boss of the 74th Floor.

Chapter 10Edit

Asuna and Kirito take a break at the safe zone of the labyrinth; both of them eating Asuna's handmade sandwiches. Kirito licks her fingers after tasting a flavor that's something similar to the outside world. Klein enters the labyrinth and sees Kirito and Asuna together. Their conversation is later interrupted by the presence of the «The Army» troops. After claiming Kirito’s mapping data, «The Army» troops march away and into the labyrinth. Kirito and the group decided to follow after them after worrying that «The Army» may challenge the boss by themselves despite their earlier warning.

Chapter 11Edit

«The Army» had challenged the boss and was suffering from their mistake; crystal usage was prohibited in the boss room and «The Gleam Eyes» was blocking the exit. Kirito and the others enter to provide support. Backed into a corner, Kirito was forced to use his secret «Unique Skill» «Dual Blades». Never has anyone seen Kirito use such a thing like that. Kirito manages to defeat the floor boss, with his HP bar in the red zone.

Chapter 12Edit

As his story has not yet ended; the fallen Kirito awoken to find Asuna crying while holding him. The remaining members of «The Army» return to their base to report the incident, and the honour of establishing the link to the next floor was left to Klein and his group. Asuna decided to take a momentary break from «KoB» and plan to stay with Kirito for a little longer.

As the hidden unique skill: «Dual Blades» was now known to the public, and the sudden rise in fame; Kirito went into hiding from the persistent crowd at the second floor of Agil’s shop, waiting for Asuna to return from the «KoB». A new problem arises when Heathcliff; the «Living Legend»; leader of the «KoB» wishes to duel with the now famous Kirito for the sake of Asuna.

Chapter 13Edit

Today presents the grand event of the duel of the two «unique skill» wielders: the «Dual Blades» vs. the «Holy Sword»; Kirito accepted Healthcliff’s challenge, under the conditions that Asuna will be given to him if he wins, and joining the «KoB» if he loses. The match proceeded with each other scything one another’s life-span, with varying chances that the winner can be either one. The match ended with Kirito’s loss, as «the Living Legend» performed an impossible move that momentarily broke the game.

Chapter 14Edit

As Kirito was a man of his word, he now joins the «KoB»; already disliking the blinding white uniform that was in contrast to his usual black coat. Much to Asuna’s surprise, Kirito confessed about the tragic end of his first guild: the «Moonlit Black Cats»; still believing that he was the trigger of their demise. Feeling his sorrow, Asuna comforted Kirito during his time of guilt.

On the first day on the job, Kirito had to attend a mandatory training course to present his skills. To Kirito’s dismay, he discovers that he had to work alongside with the last person he wanted to see: Kuradeel.

Chapter 15Edit

After Kirito relinquishes all of his crystals following Godfree’s order, the group adventures to the 55th Floor's Labyrinth. At the time of their break, Kuradeel attempted his assassination after lacing the drinking water with paralysis poison; killing one after another until the paralyzed Kirito was left alone with the murderous Kuradeel, who turned out to be one of the last remaining members of the worst Player Killing guild: «Laughing Coffin».

Despite the paralysis, Kirito struggled near to his death against Kuradeel and was rescued by the soaring Asuna, allowing Kirito to finally recover. Demonstrating why she earned the name of the «Flash», she reaps his health near to its end before allowing his surrender. To protect Asuna, Kirito ended Kuradeel’s life by stabbing deep into him with his hand. At the end, Kirito told Asuna that he would offer his life to her, and will stay with her to the very end.

Chapter 16Edit

It turns out that Asuna was monitoring the map while waiting at the 55th Floor city: «Granzam». Asuna and Kirito reported to Heathcliff about the incident, and temporarily left the guild with his permission. As Kirito did not want to be alone at the moment, he carelessly told Asuna that he wanted to be with her that night, which led to a comical chain of events that drew some attention to an interesting option on their virtual menu screen called «Ethic Code Off». After some time, Kirito finally unveiled his feelings to Asuna, and then he made his proposal to her for marriage.

Chapter 17Edit

Kirito and Asuna are now in the relationship of marriage in Aincrad, and spending their newly-wed life at a small, round cottage on the 22nd Floor. Once again, both announce their love for one another.

Chapter 18Edit

10 days have passed; both Kirito and Asuna push aside their fighting skill for the moment, and decided to train their domestic skills; Kirito on fishing, and Asuna on sewing. As luck would have it, Kirito seem to have spent it all in getting Asuna to marry him as no fish would bite. They soon met a fisherman name Nishida, and decided to help him carry out a fishing event on a later day.

Chapter 19Edit

It was the day of the fishing event; not only was Nishida, Kirito and Asuna were present but a crowd was waiting attentively for the appearance of the local god. Nishida uses his highly trained fishing skill to get the bite, and then switches for Kirito’s superior strength. What they caught, however, was an enormous Lungfish-like monster which Asuna soon killed with ease. The event ended and so did their honeymoon, as they were requested to attend the boss raid by Heathcliff the following day.

Chapter 20Edit

Kirito and Asuna returned to the «KoB» headquarters to learn of the demise of a scouting party from Heathcliff; the room of the 75th boss was discovered, however no Intel about the boss was obtained. Upon passing the gate, the boss room will isolate itself and the use of teleportation crystal will be prohibited. Despite the applied grim conditions, Heathcliff still plan to attack the boss with his strongest members and hope for the assistance of Kirito and Asuna.

Chapter 21Edit

Klein and Agil were amongst the group of high level players who gathered for the boss raid; including Kirito, Asuna, and Heathcliff. The tension rises as the man of legend lead the group through the gate of the rare «Corridor Crystal», they trespass into to the boss room with 32 players and awaited the gate to close behind. Within the isolated room, the battle commences against the skeletal centipede who can kill a player with one strike; «The Skull Reaper».

Chapter 22Edit

The battle continued for over an hour until the fall of «The Skull Reaper»; the deadliest foe so far who easily eliminated 14 players. Everyone grieved about whether it was possible to complete this game, as the fatalities and difficulties will certainly rise in the coming battles. Suddenly, thanks to Kirito's intuition, the true identity of the immortal Heathcliff was discovered to be the creator, Kayaba Akihiko. Before leaving after immobilizing everyone with the authority of the system administrator, Heathcliff decided to challenge Kirito with a one-on-one duel to the death for everyone’s freedom, which Kirito boldly accepted.

The battle rages on with the unyielding actions of Kirito and Heathcliff; both accelerating their skills to an intense manner; and it continues until Kirito commits the mistake of trusting a skill guided by the system. As the match draw near to a close, an impossible event occurs; the last attack that would have ended Kirito’s life was redirected onto the supposed immobilized Asuna who shielded him. The attack depleted the last of her remaining health, and as the one truth imagined in this world, she perished in Kirito’s arm.

Chapter 23Edit

With the loss of Asuna, Kirito lost his state of mind and fought with no longer caring for his life. After Heathcliff pierced Kirito with his blade and ended his life, the dying Kirito perform his last act by using Asuna's sword to kill Heathcliff from point blank. The battle resulted with the deaths of the two duelists and the friends of Kirito witnessing the destruction of both bodies. The infamous last boss was eliminated and thus the game was cleared.

Chapter 24Edit

Kirito finds himself staring at the steel castle in another world alongside Asuna; watching as the game executes the Final Phase; the destruction of Aincrad. They were soon interrupted by the presence of Kayaba Akihiko; the man who started it all. After explaining his motives for the death game, he left the two lovers: Kirigaya Kazuto and Yuuki Asuna for the departed world.

Chapter 25Edit

Kirito was finally freed from the game. After finding himself in the hospital, he left his bed. His body was frail and weak, but he would not rest until he got Asuna back in his arms.


Adaptation NotesEdit

  • The original Web-Novel states that 50,000 players were captured within SAO. The Light Novel publication changed this to 10,000.
  • Chapter 14 in the Light Novel had a few details changed, from when Kirito was recalling his time with Sachi.
    • In the Light Novel, after bringing up how Sachi and him were similar to each other, he points out that she one day came to him and admitted her fear of death. However, the Web Novel doesn't mention her telling him this.
    • In the Web Version of this passage, Kirito recalls how the two often spent time together, outside of simply training, but this was omitted in the Light Novel.
    • These changes seem to indicate that in the Web Novel, both Kirito and Sachi were significantly closer. This is further reinforced by a Popularity Contest Q&A, during the Web Novel's run, where Kirito says that his first love was "Someone who was in the Moonlit Black Cats," likely referring to Sachi.
  • In the original web-novel, Asuna didn't hesitate to kill Kuradeel when he began to beg for his life. In the Light Novel and Anime adaption, this was changed so that Kirito would save Asuna, after she had a moment of doubt, allowing Kuradeel an opening to disarm and then attack her.
  • It is heavily implied that Kirito and Asuna slept together, with Asuna waking up nude and clasping a blanket onto her body. Chapter 16.5 was a story by Reki, that he had placed in the "Fan Fiction" section of his site, so the validity of this scene is debatable. However this chapter was never published officially.
