Kirigaya Kazuto

Kirito (キリト) is the main protagonist of the Sword Art Online light novel series. His name, Kirito, was taken from his real name Kirigaya Kazuto (桐ヶ谷和人). "Kiri--" from Kirigaya and "to" from Kazuto. He was chosen as one of the 1000 beta testers for the Closed Beta of « Sword Art Online », the first ever VRMMORPG for the NerveGear.

Real World / Sword Art Online / Project Alicization Avatar
During the beginning of the game and during the beta-testing phase, Kirito's avatar had the appearance of a handsome antagonist older than he actually was. Kirito has slightly long but neat black hair and black eyes. His delicate face showed no trace of masculinity, allowing people to mistake him for a girl. After using the «Hand Mirror», the item which Kayaba Akihiko gifted to all participants, his avatar changed to reflect his real physical appearance.



After the initial stages, he becomes well known in SAO as the «Black Swordsman» (黒の剣士) due to his tendency to wear black clothing. He uses two swords after his Sword Skill «Dual Blades» is revealed, the black «Elucidator» and the white «Dark Repulser». He later donned the red and white uniform of the Knights of the Blood after being defeated by its leader Heathcliff in a public duel and being forced to join his guild.

In the real world he has a tendency to gravitate towards dark colored clothes.

In the beginning of Project Alicization, he used hand-sewn pale blue short sleeved shirt with V-shaped cut on the chest which is tied with a light brown cord along with trousers and hand-sewn leather shoes. Two years later, when he is a valet in the Master Sword Academy, he wears the standard gray uniform like everyone else. When he becomes one of the top 12 in the school and is allowed to choose a color for his uniform, he wears a pitch black uniform.

Kirito's initial appearance was that of a default «Spriggan», which he chose because of the race's black-themed equipment. Instead of the normal black forelocks hanging from his head, his black hair stood in natural spikes. His large eyes appeared mischievous, and he had pointy ears and dark grey-ish blue wings. During Mother's Rosario his hair go down rather than his normal spikes. He is equipped with a large broadsword intended for larger players like «Imps». He will occasionally dual wield using his experience from SAO.



After converting his avatar back from his brief stint in Gun Gale Online, his previously unkempt hair stays down, though his mischievous black eyes remain the same. He also receives a new coat and switches his broadsword with a new long sword.

In late December, 2025, he obtains the «Holy Sword Excaliber», and uses it for his dual wielding weapon.

Kirito's avatar in GGO is the rare «M9000» type, which is given to players with extensive playtime. It is an avatar that many male players dream of having one day due to its female appearance. He retains his black hair, which now flows down to his shoulders. He has pale skin and crimson lips, and shining black eyes, fringed by long eyelashes. If one did not know better, they would easily say that he was female. This often causes great confusion to people, such as Sinon.

He is equipped with a 5.7mm FN Five Seven handgun and «Kagemitsu G4» photon sword.

Personality
Kirito is someone who is not good with words as said by Klein and can be quite direct. This is due to him not having many friendships and closing others off, because of his love for computers. As such he can come off as a rude person to others such as Lisbeth and Sinon. He sometimes actually seems to enjoy angering and teasing people as well. Also from time to time, Kirito can be quite overconfident thinking he can do things others can not.

He is almost always a calm and collected character, rarely showing any signs of distress. When Kayaba Akihito appeared in SAO and announced that it was the Death Game, Kirito showed only a slight reaction, while many others panicked. He has shown different moods throughout the series; at times being rather cheerful, and being gloomy at others. When in a battle, he becomes incredibly fierce and aggressive. Sometimes, his fierceness is up to the point where he unable to notice what he has done.

However, Kirito is actually a kind person who just is misunderstood. Despite the general population opinion towards Beta Testers in SAO, he refused to abandon another player in trouble. This is only strengthened after the Black Cats of the Full Moon demise. He also comforts others who are scared or down such as Silica after she lost Pina. He claims to help some female players in SAO because they remind him of his sister, who he feels guilty for believing he forced her into kendo. These kind acts have earn him respect and affection from many girls. Kirito, unlike usual male heroes, is not very dense as he was able to tell Lisbeth was going to confess to him before Asuna interrupted.

Kirito is also a very emotional person and lets his emotions control him from time to time. The deaths of Sachi and Black Cats of the Full Moon haunted him until his marriage with Asuna. Sachi's death in particular had a huge affect on his personality, and motives; making him very distant from others for a while. He temporaily loses his will to live when Asuna's character was killed by Heathcliff. This worries his friends and allies as Kirito is someone who would let guilt ruin his life if not comforted. He also tries to hide his abilities not wanting unneeded attention.

A person with incredibly strong resolve, Kirito will do anything and everything in his power to accomplish something that's important to him, without any hesitation. When Asuna was being held in Alfheim, Kirito was bound and determined to set her free, and when he located her, he immediately tried to fly up to the tree, which had already been found to be an impossibe task, and tried to fight his way to the top by himself.

After escaping SAO, Kirito attempts to repair his relationship with Suguha, his cousin. This shows Kirito is now attempting to make up for his past mistake of ignoring her, showing a sense of maturity. Kirito, later in the series, is shown to be a calm and mature player who can be teasing as well (something that annoys Sinon to no end being his main target).

Background
Born on October 7, 2008, Kirigaya Kazuto was adopted by his aunt and uncle a year after his birth when his biological parents died in an accident. Raised by his foster parents as a son, he originally trained with his cousin in the neighborhood kendo dojo under their grandfather's tutelage. Due to his aunt's influence as an editor for a computer systems magazine, Kazuto fell in love with computers and dropped kendo after two years.

Kazuto has immense skill as a programmer, managing to build a computer from parts during elementary school, finding his erased records in the national registry at the age of ten, as well as managing to stop the SAO server from deleting Yui by converting her program into an object and storing her into his Nerve Gear as environmental data.

He currently lives at Kawagoe City in the Saitama prefecture with his family, adopted by his aunt and uncle after his parents died, though his uncle is often not around. He was raised as their son with his cousin as his sister. He was originally trained in kendo by his grandfather but had little interest in it, and as a result his sister began to cover for him.

Sword Art Online Closed Beta
One of the lucky 1000 players accepted into the beta, Kirito logs hundreds of hours of playtime. He, along with the other top players, were able to reach the eighth floor before the beta had ended.

Sword Art Online
Shortly after logging in to the now fully released SAO, Kirito is stopped by a stranger. Klein, a new guy, asks for his help in learning how to play. After befriending each other and training in the fields for several hours, they are forcefully teleported back to the Town of Beginnings, to receive an announcement from Kayaba Akihiko. He reveals that the lack of a log out function, which they had recently realized, was a "feature" of his new game, and that forced removal of the Nerve Gear head piece from the other side will fry the person's brain using microwaves.

The only means to escape is to clear the game; that is, to successfully defeat all 100 levels of Aincrad and defeat the final boss. Kirito immediately grabs Klein and runs off, and after hearing that Klein will remain with his friends here, he leaves him and heads off to the next town.

The First Day
Kirito spends the first day making his way to the next village. He has decided to complete a quest to obtain a new sword (of which he knows about by participating in the beta). During this quest he encounters another player, a beta tester named Coper, who proposes they form a party and complete it together. After a while, a trap monster appears and Coper purposely trips it. Kirito quickly realizes that Coper was trying to kill him and take the rare quest drop himself. Kirito manages to escape, but Coper, who does not know that his «Hiding» skill will not work in this situation, dies. This causes Kirito's mortality to heavily weigh on him.

Aria in the Starless Night
One month into the game, 2000 people have died, and the first floor has yet to be cleared. Kirito encounters a player in the first dungeon and realizes that it was a female player. The player fainted, so Kirito carried her outside the dungeon they were in. He insisted that he only save her in order to save the map data which she later gave. But before she depart, Kirito suggest that she should go to the First floor Boss Strategy conference than going to the dungeon at Tolbana.

They arrive to Tolbana, but they momentarily part ways. Kirito soon met up with «Argo the Rat» and learns that the buyer of his «Anneal Blade +6» had raised his price to 29,800 «Colls»; however Kirito again refuses the offer and wonders why the Argo's client was so persistent.

Kirito later finds and join the player from the dungeon, they both began to eat their bread. Kirito gives her a pot of cream and later explain how he obtain the item and offer to give tips on how to gain the item efficiently but was quickly rejected by the player, stating that she didn't come to the town to eat good food. Kirito question why she was in the town and listen to her explanation. After the clarification, Kirito begins to apology but was intruded by the clock bell. The player realizes that the meeting was about to start so they both head to the conference.



The next day, they both go to a meeting organized by a player named Diabel. Forty four people go to the meeting and decide to try to defeat the boss of the first floor. During the boss fight Kirito is put in support for the E group along with Asuna. They are in charge of clearing the mob monsters that accompany the boss. During the fight, Diabel dies, causing everyone to panic and Kirito to recognizes Diabel from the beta test. He reorganizes everyone to attack the boss again, with Asuna's help he gets a last attack and is awarded the Coat of Midnight. After the fight, many grieve the loss of Diabel and say that this is all the beta testers fault. Kirito then realizes that normal players must make peace with the beta testers and declares himself as a Beater, thereby isolating the hate directed at the beta testers to himself. Asuna and Agil, two of the clearers, were the only ones who understood his intention.

Rondo of the Transient Sword
Kirito visits a town looking for a blacksmith to enhance his Anneal Blade to +7, he finds Asuna and both watch a discussion between two players, because one of them, the blacksmith, failed four consective times to enhance his weapon.

Kirito decides to help Asuna to gather more materials to enhance her Wind Fleuret, so they make a bet, which Kirito loses and has to treat her dinner, she chooses a restaurant that he knew, and after exiting, they find out that they got a luck buff, so he takes Asuna to the blackmith to try to enhance, and although it had a 97% success, it failed and the weapon dissapeared.

After calming Asuna and taking her to an Inn, he returns and follows Nezuha into a bar, where he encounters him talking to some friends about business and saying that it was good (contrary to all those failures). Kirito notices something and returns running to Asuna's Inn and enters her room abruptly, makes her materialize all her items, but at the end, he finds her Wind Fleuret.

Red-nosed Reindeer
With the approach of Christmas eve, all of the NPCs start talking about a mysterious monster which will appear on Christmas and drop rare items if defeated, causing players to look for clues regarding its future location but nobody finds a good lead. Kirito found Klein and talked to him for a while. They did not care about the boss until they learned that it will drop a resurrection item, so Klein started looking for Kirito for help on defeating this boss.



With the news, he remembers his time with Sachi and the Black Cats of the Full Moon and remembers how it all began, how he hid his higher level from them and helped them reach higher levels. One day Sachi ran from the group, Kirito used his Tracking skill to find her and formed some kind of relation with her, he made her forget her fear of dying and she helped him to clear his conscience from lying to the other members of the guild. One day the group decide to hunt for treasure while their leader, Keita, was off. They ignored Kirito's advice and activated a trap, causing a bunch monsters to surround them. Kirito survived due to his relatively high level, but the others were killed. He returned to the town and told everything to their leader, and the shock of the death of his companions caused Keita to commit suicide.

Kirito managed to find the area, but was followed by Klein and his guild, and then by the Divine Dragon Alliance guild. Klein and his guild stopped the other guild while Kirito fought Nicolas the Regenade. At the end of the fight, Kirito was barely holding off. He had not ever been so close to dead, but he won and obtained the Divine Stone of Returning Soul. However, to his surprise and frustration, the item only resurrected people within 10 seconds of their HP reaching 0, so it was useless for him. He gave the Divine Stone of Returning Soul to Klein and slowly walked back to the town. Klein tells him that he must not die, that he must beat the game and save everyone.

The Black Swordsman
Upon encountering Silica in the Forest of Wandering, he saves her from a party of attacking «Drunken Apes». He apologizes for being unable to save Pina, her dragon, but tells her that it is possible to revive Pina. After explaining the process he gives some equipment to Silica and takes her back to the town. He talks with Silica during dinner and before sleeping, which is when he explains that he is helping Silica because she reminds him of his sister.



The next day, they depart to the 55th floor to find the Flower of Pneuma. On their way back, after find the flower but are ambushed by the members of the Titan's Hand Guild, who want the same flower. They attack Kirito but are easily defeated by his overwhelming skill. Finally Kirito reveals that he was looking for them because of a request from a leader of another guild those members were all killed, with the exception of the leader, by the Titan's Hand guild.

Kirito sends the bandits to The Army's prison and he and Silica promise to meet again in the real world.

A Murder Case in the Area
Kirito is taking a quick nap while enjoying the day because the weather was very good, but is interrupted by Asuna, who scolds him for wasting time while the other front liners are training, but he convinces her to lie next to him. Kirito wakes up and notices that Asuna is completely asleep, so he remains near to protect her. When she wakes up she gets angry but realizes what he has done and invites him to have dinner to call it even.

Generally speaking, you cannot kill someone within the safe zones (AREA). Two exceptions to this rule are known to exist: One is to challenge a sleeping opponent to an all-out duel, and move their finger to accept. The second is to drag a sleeping opponent outside of the safe zone, whereby they can be targeted normally. After watching a man be hung by a noose, then die from being impaled by damage-over-time, Kirito and Asuna begin investigating how that happened and why. This mystery touches upon the past of a long-forgotten guild, Golden Apple, and the reason behind the death of its female guild leader.

Warmth of the Heart
Kirito charges into Lisbeth's store after being introduced to the place by Asuna. He wants Lisbeth to create him a sword that is on par with his «Elucidator». After allowing Kirito to see her best sword, he breaks it during a test run. Thus, the two embark on a journey to obtain a «Crystalite Ingot» to forge what would eventually be known as «Dark Repulser».

Year II
After two years within SAO, Kirito is a clearer and is currently on the frontlines which are now located on the 74th floor. He goes on a mapping run with Asuna, a friend of his and sub-leader of the Knights of Blood guild. Together they find the boss room. On the way back they encounter a unit of "The Army," who they assume will try to challenge the boss. They chase after them to try to convince them to stop, but the Army ignores their warnings and continue on. Once inside the boss room, the Army players realize that the room is an "anti-crystal area" so they can neither heal or escape.

Upon arriving, Asuna impulsively runs in to help them, and Kirito quickly follows her. He is forced to activate his "Dual Blades" secret skill to save Asuna and the others. After the boss fight, word about Kirito's ability spreads throughout Aincrad. Asuna asks for a temporary leave of absence from her guild and Heathcliff, the leader, says that he will only allow permission if Kirito defeats him in a duel. If Kirito loses, he will have to join the guild. Kirito accepts the challenge and is on the verge of winning, but at the last moment Heathcliff moves with impossible speed. The duel ends with Kirito's loss, forcing him to abide by their deal. A few days after joining the KoB, he is sent on a mandatory training run with some other members. During this exercise, he and the two others are betrayed by Kuradeel. Kuradeel kills the others and saves Kirito for last, but Asuna barely manages to save him. She lets Kuradeel live, but he attacks them again and Kirito is forced to kill him.

After this, Kirito announces his feelings for her, and again they ask for leave. They get married and go on a honeymoon on the 22nd floor.

Morning Dew Girl
While Asuna and Kirito were on their honeymoon on the 22nd floor, they receive a rumor of a ghost in the forest and decided to go check it. In the forest they found a young girl who goes by the name of Yui, to their surprise, she is an AI whose purpose was to monitor the mental health of SAO players. Asuna and Kirito decided to adopt Yui as their daughter.



Yui's program was saved into a crystal necklace, with the help of Kirito who excels at programming skill, to prevent the SAO operating system Cardinal from deleting Yui as a purge against interference by foreign object. This data is saved as environmental data within Kirito's NerveGear in hope of reviving Yui in the future.

Return to the Frontlines
After the second week of their honeymoon they get a call: the boss room of the 75th floor has been found. They return to the frontlines and participate in the battle. During the battle Kirito, Asuna, and Heathcliff manage to hold back the incredibly powerful boss while the rest of the players attack him. After the long battle Kirito has an intuitive realization that Heathcliff is none other than Kayaba Akihiko himself and proves that fact by attacking him, revealing his "Immortal Object" status. Kayaba applauds Kirito and tells him that he will be waiting on the 100th floor as the final boss... unless Kirito wishes to have a duel right now.



Kirito agrees despite Asuna begging him otherwise. After a few minutes of fighting, Kirito becomes enraged and uses a sword skill, and Kayaba, knowing the system all too well, takes advantage of the delay to finish him off, but Asuna quickly intercepts the blow for him, despite her paralysis, and dies from the attack. Kirito, filled with rage, attacks Kayaba thoughtlessly and is quickly struck down.



Through a final push of his will, and even delaying his death, he stabs Kayaba in the chest with Asuna's blade. Kayaba and Kirito both vanish, ending up in an area located above Aincrad along with Asuna. Kayaba explains his reasons as to why he created SAO before vanishing along with his castle. Kirito wakes up in a hospital bed, his body frail and weak, and vows to find Asuna.

ALfheim Online
After SAO was cleared and Kazuto wakes up in a Tokyo hospital, he wanders off to find Asuna, but is discovered by nurses and returned to his room. Tens of minutes later, he is visited by a representative of the «Ministry of Internal Affairs — SAO Countermeasures Division» who Kazuto inquires about Asuna's whearabouts, as a condition to share information about the SAO incident with them. After a short call, the representative informs him that 300 players, including Asuna, had not yet woken up from their comatose state. At some point, Kazuto, leaving a note of his plans, attempts to return to the world of SAO via his NerveGear to find his lover, but, unfortunately, receives the error message «Error: Cannot connect to server».

By the time two months have passed after the incident, Kazuto returns home to his family and has completed his rehabilitation, which allowed him to freely move again. As soon as he was able to move freely, he started visiting Asuna, at the hospital she was admitted to, every 3 days. One day, during one of such visits, Asuna's father, Yuuki Shouzou, and Sugou Nobuyuki, the latter being a person who Kazuto had not met before, come into the hospital room. After Sugou is introduced, he tells Shouzou that he plans on having Asuna wear her bridal gown the next month. As soon as Shouzou leaves the room, Sugou reveals his true self to Kazuto. Sugou starts stroking Asuna's hair in front of Kazuto and tells the boy that he plans on marrying Asuna, who is still in a comatose state, even mentioning that he has the right to do so, because his department at RECTO is responsible for maintaining the SAO servers and, in turn, keeping Asuna alive. Just before leaving the room, he invites Kazuto to the wedding, leaving the boy helpless to do anything. That evening, Kazuto's sister Suguha finds him alone in his dark and cold room in a state of deep despair and self-loathing and, after telling his sister that Asuna was out of his reach and how useless he felt, he begins crying like a child in front of her. After closing the window, Suguha comforts her brother and encourages him not to give up so easily, before supporting him and gently lowering him onto his bed, where after awhile, his cries turn into a peaceful sound of sleep.

The next morning, Kazuto wakes up and finds his sister sleeping next to him in her pajamas. He then recalls what had happened the night before and, due to Suguha's encouragement, has renewed his resolve to save Asuna. Shortly after waking his sister up, who runs out of the room in embarrassment after realizing what had happened, he receives an e-mail from Agil, that contained a picture of a virtual world, where a bird cage could be seen in the foreground and in that cage was a girl who looked just like Asuna. Kazuto immediately calls Agil to ask him about the photo and agrees to meet him at the Dicey Cafe. After the shortest shower in his life and drying his hair in a rush, he quickly heads out to the cafe by bike. Once there, Agil, or Andrew in real life, brings out a rectangular package, a client for the new VRMMO game called ALfheim Online, and tells him about NerveGear's successor, AmuSphere and the game. He then tells Kazuto that the picture with the girl that looks like Asuna was taken inside of the game, at the top of the World Tree, when a group of players came up with the idea of using a multi-stage rocket flight formation to propel themselves, which allowed them to reach the lowest branches of the tree, where they took the screenshot. After noticing that the game was designed by RECTO Progress and remembering that Sugou, who worked there, said that he was in charge of the SAO servers, he realized that a girl who looked like Asuna in a game designed by a RECTO subsidiary couldn't have been just a coincidence. Thinking to himself that contacting the Ministry of Internal Affairs without concrete evidence was a bad idea, he asks Andrew to let him have the game client to personally confirm whether Asuna really was trapped in that game.

Having returned home, he returns to his room, where he inserts the ALO client into his NerveGear and dives into the game. At the character creation screen, he inserts his character name and password, but after realizing that Sugou was aware of his character name, he changes it from its romanized form to its kana and then proceeds to choosing his character's race. Although, normally he would read about the strengths and weaknesses of each race, due to being pressed by time and not planning to play the game too seriously, he selects the Spriggan race because of its initial black themed equipment and completes the initial setup procedure. He is then sent into a vortex of light and enters the game world, floating in the air above the Spriggan capital. However, at that point, the world around him began to dissolve and collapse altogether, as he descended into the darkness.

After reviewing his items, he discovers the item: Yui's Heart. After using the item, Yui appears in the game and tells Kirito that the ALO server is just an older version of the SAO server and so all his skills remained intact and besides that, teaches him about the flying system in the game. Later he ends up right in the middle of a fight between Leafa and three Salamanders. Kirito decides to help Leafa and easily defeats the 3 Salamnaders that were fighting her. Afterwards he introduces Yui to Leafa and asks her for some help for the game. She teaches him the advanced control flying system and later decides to help them reach Aarun.

Gun Gale Online
When Kikuoka, who is in charge of net crimes division calls him to a pastry shop to chat, he finds out about «Death Gun». Hearing about the potential threat Kirito agrees to investigate GGO for a fee. Kikuoka sets up a hospitol room for Kirito to dive in, and Nurse Aki (the nurse that took care of him during the SAO incident) to observe any abnormalities in his heart rate and verything related to his health and mental stability during he dives. Before he perform the first fulldives, he tells Nurse Aki how he killed 3 Laughing Coffin members (one was Kuradeel in order to protect Asuna, and the other two were when him and 50 other frontline players had attacked their secret base to stop this killing guild from action). Upon converting, he is stunned at his appearance being extremely feminine. He encounters Sinon asking for help. She offers to help him get started. Kirito, with minimal funds and against Sinon's advice participates in the bullet dodging game. Kirito, using his previous experience, successfully wins the game and wins a large amount of funds.

He uses all his funds in buying a laser sword named Kagemitsu G4, a five-seven handgun named FN Five-Seven and some equipments to participate in the 3rd Bullet of Bullets event. After a rush through the city Sinon and him enter the tournament, in it Kirito uses a never before seen battle style in which he deflects the bullets with his sword. Kirito and Sinon manage to get into the finals held the next day, although Kirito is shocked by his encounter with Death Gun.

The next day Kirito is confronted by Suguha, who discovered him in a video games news site. Kirito waits for the afternoon and enters GGO, he sees Sinon and calls her to talk. In the tournament finals he finds a way to disappear from the map by swimming underwater and with Sinon they watch how Death Gun dispatches another player, they trail him to the central city on the stage, where he takes out Musketeer X and returns just in time to save Sinon from Death Gun, who managed to slip behind her, they somehow escape and hide in the desert, where Sinon tells him her backstory and Kirito comforts her.

After talking for a while they discover the secret behind Death Gun and how he got the addresses of the players and his companion would kill them in the real world, so they prepare a plan to take him down, using Kirito as a bait. During the battle Kirito senses Asuna's hand and reminds of the gun he had not used and performs the double circular skill with the gun and his sword, finally killing Death Gun and then uses a grenade to tie with Sinon in the first place.

After logging out he hurries to Sinon's house and arrives just in time to save her from on of Death Gun's accomplices, two days later he visits Shino's school and takes her to meet Kikuoka, after discussing the recent incident he takes her to the Dice Cafe, where he meets Asuna and Lisbeth, as well as a woman she saved during the incident in the post office.

He helps the Sleeping Knights clear the 28th floor along with his friends, then faces Yuuki and loses again, but this time in the ALO Sword Tournament finals, though he once more did not fight with dual blades.

Project Alicization
Recruited by Kikuoka for an experiment with a new form of VR system, developed by the mysterious company RATH, Kirito awakens in a fantasy style forest with no memory of how he got there. There, he meets a teenage woodcutter named Eugeo, who seems too life-like to be a NPC.

Alicization Beginning
He meets Sinon at the Dicey Cafe, where they talk while waiting for Asuna to arrive, when she arrives, they show Sinon the GPS and monitoring devices created by Kirito for each of them to monitor each other. They proceed to talk about Kazuto's half-time job, that he does not remember anything about the time he full-dived and the system based on the acceleration of time perception for the user. Later they depart and Kirito insists to accompany Asuna to her house, but just before arriving he turns back and faces Johnny Black who was following them, he defends Asuna but is injected by Succinylcholine and is later taken in an ambulance.

Kirito wakes up in a forest in an unknown place, while wondering where he is, he hears a strange noise and when he finds the source he meets a boy called Eugeo who explains him the basics of the world and takes him to his town, In the town he meets other people, and decides to stay there. Kirito unintentionally causes Selka to run into a certain cave and get captured, causing Kirito ans Eugeo to go after her. They defeat the Goblins, but Eugeo got heavily wounded. Kirito wakes up Selka, who was lying in a cart, and Selka, with Kirito's assistance, saves Eugeo. They all go back to the village. Eugeo finishes his current Sacred Task and chooses his next, being a swordsman.

Alicization Running
With the interlude it is explained that he is immersed in the Underworld to reconnect his neural pathways that were destroyed when his heart stopped as a product of Johnny Black's attack.

In the Underworld, various months have passed since he and Eugeo left Rulid Village, they participate in the Zakkaria Sword Arts Tournament, he faces Egome Zakkalight, a sixth class noble, who uses a stronger sword to get advantage over Kirito, but he turns the tables by using Snake Bite sword skill to brake his sword and win.

Months later he enroled along with Eugeo in the Northgarlan Sword Master Academy, and became valets for the elite swordmen. Kirito is training with Solterina Celulute, and after the practice, he returns to his dorm and talks to Eugeo, who reminds him that the next day, after a complete year, he'll recieve the sword that was carved from the branch of the Gigas Cedar.

As punishment, he must sparr with Uolo, who tries to win in one hit as always, but Kirito stops him with the 4 hits from vertical square. A supervisor intervenes and declares an tie, thus, ending the duel.

Relationships

 * See Kirito's Relationships

When Kirito starts to love computers, he does not like to interact with other people, including his cousin Suguha. But after completing SAO and ALO, he maintains his relationship with his friends and acquaintances from SAO and ALO. He continues to make relationships with other people as the series progresses.

In the real world he has problems establishing relationships with people, especially women, but in the games he easily makes friends even more so with women than men.
