She is an undine with 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.

Personality
Asuna originally didn't care about dying in the game, before meeting Kirito. That meeting drastically change Asuna 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 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 arguement 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 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. It also earned her the title as «The Flash» (閃光).

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

Sword Art Online
She is the subleader of the Knights of the Blood in SAO, where she was first 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 Yui], their adopted AI daughter and save Sinker, the CEO of «The Army», in the end, Yui was transferred into a necklace for her protection which Asuna wore with her.

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 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 her medical AmuShpere ("Medicuboid") in the hospital, to attend school and walk amongst the streets. In the end, after Yuuki dies, Asuna reflected on her attitude and the way of life.
