Reality/Sword Art Online Avatar
She has long orange-brownish chestnut hair and hazel eyes, in SAO she wears the red and white uniform of all «Knights of the Blood» and wields a rapier made by Lisbeth called «Lambent Light».

ALfheim Online Avatar
Her original avatar in ALfheim, was as Fairy Queen, Titania. She wore a white outfit, with a white long skirt, tube top showing her belly, along with a red ribbon that goes around the top part of her top that comes together to make a bow. She goes barefoot, and wears a white strip around her ankles.

After being rescued by Kirito and returning to the game, she creates a new avatar, which is an Undine. She has light blue hair with an appearance that otherwise slightly differs from her SAO avatar. Her class is a healer, later known as «Berserk Healer» due to the fact that she enjoys fighting in the front line with her rapier occasionally, despite her role as a healer. Her Undine avatar is from her main account that was transferred from SAO. She also made a new account and trained a new character from scratch: the Sylph «Erika». The reason she created a new character was extremely simple: Sometimes she wanted to change her appearance too. «Erika» specialized in melee and had most of its ability points devoted to dagger skills, so it was more suited for duels than Asuna which was a half healer.

Personality
Asuna originally didn't care about dying in the game, before meeting Kirito. That meeting drastically changed Asuna's personality and outlook on life. She soon takes most things Kirito says to heart and looks to him for help, using him as somewhat of a lifeline. She acts as a tsundere towards him for most of Volume 1, even when married.

Asuna is a kind and helpful young woman, who is similar to Kirito, cannot abandon another in trouble. She takes the game very seriously and is very focused on clearing it, before Kirito tells her to enjoy SAO a bit. Asuna is also somewhat proud and is not afraid to get physical with those that challenge her authority or brag about her abilities such as Cooking. She even challenged Kirito to a duel after an argument over how to handle a Floor Boss. She isn't afraid to act out on her own and will take matters in her own hands from time to time.

Asuna, once again similar to Kirito, is someone who can be controlled by her emotions many times. This is best shown in moments with Kirito where she jumped in front of an attack meant for him by Heathcliff and appeared to be killed. She also can't handle the deaths of others well and will lose control, attacking The Gleam Eyes after seeing the Liberation Army get slaughtered.

In ALO, after being saved by Kirito, Asuna's personality hasn't changed a bit except she's not as proud as she was in SAO. Her personality begins to develop further after meeting Yuuki. Seeing how, despite knowing she will die, Yuuki can still move forward, Asuna takes after her and resolves after her new friend's death to keep moving forward. She is also either dense to the fact that other girls having feelings for Kirito, or she knows that Kirito is only in love with her, and so it doesn't bother her.

Background
She logged in SAO after she borrowed her brother's Nerve Gear when he had a sudden business trip and could not play on the opening day. When she discovered all the players were trapped in SAO she held herself up inside her room in «Starting City» for a week, before resolving to take fate into her own hands. This led her to kill monsters at an incredible rate and level up in a quick fashion, even risking her life in the process. It also earned her the title as «The Flash» (閃光)? for performing as astounding «Linear».

She's the wife of Kirito in-game and his girlfriend in the real world.

Aria in the Starless Night
Asuna had spent 3-4 days battling in the first floor's dungeons, having taken 5 Iron-Rapiers with her, and planning to return as soon as her last one was at half durability, when Kirito came upon her he saw her elegant «Linear» attack. After explaining that using Linear on an enemy with nearly no health was «Overkill» Asuna said there was no problem with it, as even if it exhausted her, she expected to die eventually, anyways. She fainted shortly afterwards, and rather than leave her behind, Kirito carried her out of the dungeon, and waited for her to wake up outside. After 7 hours, when she woke, she claimed that his actions were unnesesary, but he insisted that his reason for saving her was for her map-data, that she must have collected after having been inside the dungeon for 3 days straight. Asuna gives Kirito the map data. But before she could leave, he informs her of the First Floor Boss Raid Strategy Meeting in «Tolbana» that afternoon. She decides to go with him, and after reaching town, the two split up briefly.

The two eventually meet up again, when Asuna is buying bread. Kirito decides to share cream that he obtained from a quest, with Asuna, which gave the bread a suprisingly better taste. Asuna thanks him for the bread, but explains she isn't here to eat food. She explains her reason for coming, and Kirito apologizes. At this point, Asuna mentions it's time for the meeting, and the two go. The meeting was to organize a large raid, to explore the dungeon, and find the entrance to the boss room. The next day, the Boss Room was found, which prompted another meeting. After discussing the information they knew, they were informed that Argo's guide had information regarding the boss from the beta period. They planned to attack the boss the next day, and Asuna and Kirito decided to party up as they where the only ones with no other to form a party, seeing as Kirito invited Asuna. During the planning, their party was decided to be a support group for attacking the smaller mobs in the room. Though Asuna disagreed with this, Kirito explained that it made sense, as they were only 2 people.

After the meeting, Kirito and Asuna were to have a conversation regarding something he said during the meeting, but Asuna didn't want to have it in public. Kirito let it slip that he had a floor in a farmer's house, with a view and a bath, which Asuna wished to see. After agreeing, he guided her to his home, and allowed her to take a bath. In the middle of her bath, Argo came to visit Kirito, regarding a client who wished to buy his sword. Kirito tried to hurridly rush Argo out, but eventually became caught up in thought, in that same instant Argo decided to enter the bath-room to change her clothes. Humorously, Kirito heard a scream, and only remembered someone running out of the bath-room that was not Argo, before blacking out.

The next day, the two join the raid group, and head for the boss room. After reaching the battle, the players go into the formation planned in the meeting, and everything seems to go well, until the boss's health drops below a quarter! At this point, the boss pulled out its secondary weapon, which, unexpectedly was a Katana, and not what was originally predicted. This resulted in sword-skills everyone was unfamiliar with, and caused the death of Diabel. In his last words, he called for Kirito to defeat the boss. Along with Agil, she assists Kirito to finally beat the boss.

Kirito alone climbed the stairs to the second floor, and after reaching the top, Asuna came behind him, and spoke with him briefly. Kirito advised her to join a guild if someone she trusts invites her, before heading to the nearest town to activate the gate there.

Rondo of the Transient Sword
Asuna finds Kirito 4 days after clearing the first boss, watching a scene of a player arguing with SAO's first known blacksmith, Nezha, because he  failed a weapon enhancement 4 times in a row. After the conmotion is cleared, they talk and Kirito decides to help her gather more materials for enhancing her Wind Fleuret.

On the field she makes a bet with Kirito and wins, so he invites her for dinner, and she chose a restaurant recomended by Argo, after eating they find out that they got a luck buff, so Kirito takes her to the Blacksmith from earlier and try for the upgrade, despite the 97% success rate, the blacksmith fails and her Wind Fleuret dissapears due to a new penalty in the game.

With tears in her eyes, she walks with Kirito, they sit on a bench and later checks in a Inn. Minutes later Kirito abruptly enters her room and makes her materialize all her items and finds under the big pile the Wind Fleuret. She asks Kirito to explain how he got her beloved weapon back and he explains her about the droping weapon system and the scam that the blacksmith named Nezha was comiting.

Year II
Asuna became subleader of the Knights of the Blood guild in SAO, shortly after the 25th floor was cleared, after the main raiding party (Aincrad Liberation Force) was nearly wiped out. After joining the guild, she constantly disagreed with Kirito in the meetings on how to beat the floor bosses. Kirito disagrees with her plan but she enforces it. One day Kirito convinced her to take a break since they were alive at that moment in Aincrad, reluctantly she leans on the grass and fells asleep. Hours later she wakes up from the grass embarassed and then offers Kirito a dinner so they would be even, for watching after her while she slept. While ordering they see a murder in a safe-zone, and knowing that it might get dangerous in the future they both secide to leave the front lines. They solve the mystery and become closer. Then Asuna's best friend Lizbeth realized Asuna and Kirito had feelings for each other and painfully backed off after making him a sword. When she was shown offering to cook Kirito's Ragout Rabbit, She parties with Kirito for a day and together found the 74th floor boss before retreating to a safe area where they encounter Klein and his guild, «Fuurinkazan» and troops from «The Army».

When «The Army»'s troops leave to battle the boss, their group follows behind, worried, but are stalled by a group of lizardmen. Upon arrival at the door, they discover with horror that the troops are unable to escape and Asuna rushes in to help, only to be rescued by Kirito. Together with Klein, she attacks the boss while Kirito prepares his «Dual Blades», then watches with worry as the two clashed with Kirito barely scraping a win. She heals him with a potion before resting on his shoulder and declaring her intent to take a break from the guild and party with him. When she returned to «Grandum», to apply for leave, Heathcliff tells her that he wishes to duel Kirito and she rushed back to inform him whereby on return to Grandum, the challenge was accepted and Kirito lost, having to join the KoB. When Kirito confides in her his dark past, she comforts him before heading to receive a mission, only to be sidelined when Kirito has to go for a test. She watched the map anxiously and upon discovering Godfrey's disappearance, rushed to save Kirito with speed supposedly exceeding the stats. She saves Kirito from Kuradeel, but was unable to deal the finishing blow, and was almost attacked before Kirito killed Kuradeel. In despair, she almost left before Kirito comforted her and kissed her. That night, she misunderstood Kirito's intent to stay with her and was greatly embarrassed. Once things were cleared up, they slept with each other and Kirito proposed to her that night. They moved to the 22nd floor of Aincrad to have a peaceful honeymoon which led to encounter of Yui, their adopted AI daughter and save Thinker, the CEO of «The Army», in the end, Yui was transferred into a necklace for her protection which Asuna wore with her.

Originally, she makes her escape into the lab facility within the World Tree, stealing an admin card, only to be caught and returned to her prison. She is saved by Kirito with Sugou going to jail after being defeated by Kirito.

Mother's Rosario
Asuna met a person who goes by the nickname of «Absolute Sword» in ALO. Absolute Sword ("Yuuki"), invited Asuna to join her to defeat a boss with her guild the «Sleeping Knights». Asuna later learns Yuuki and other members of the «Sleeping Knights» were terminally ill patients who have been under FullDive for longer than even the SAO survivors. To Asuna's shock, Yuuki has only a few remaining months before she dies. She decided to help Yuuki to experience life to its fullest with the help of Kirito's VR probe that can be operated by Yuuki through the Medicuboid she was using in the hospital, to attend school and walk amongst the streets. In the end, after Yuuki dies, Asuna reflected on her attitude and way of life. She commits that no matter what hardship she will face in life, she will continue to fight for her happiness and refuse to give up just like Yuuki.

Alicization Beginnning
Asuna learned about the part-time job that Kirito was doing, an imaginary virtual world that accelerates time from many generations in a matter of minutes through computer-programmed artificial intelligences. Soon after she found about this information in detail at Dicey Cafe, Kirito and she leaves to her home. However, a vengeful former player of Sword Art Online from the guild Laughing Coffin, Johnny Black, unleashes his anger on Kirito, severely injuring the latter.

Alicization Running
Asuna quickly takes him to the hospital, and while they return him back to life in a comatose, he disappears the next day. With her deductive reasoning, she figures out that he is kidnapped to an turtle-like laboratory in the middle of the ocean.

 * The Anime depics Asuna and Kirito having met at the Meeting in «Tolbana», rather than in the dungeons, where Kirito informs Asuna about the meeting.

 * After the boss battle, Asuna runs up to Kirito while he is still climbing the stairs, rather than catching up to him when he was already out-side.
