Yuuki Asuna

Asuna originally did not 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.

Asuna is a kind and helpful young woman who, similarly to Kirito, cannot abandon another in trouble. She takes the game very seriously and is determined to clear it before Kirito tells her to enjoy SAO a bit. Asuna is also somewhat proud and despite her kind personality, she will not hesitate to get physical with those that challenge her authority or make fun of her abilities, such as cooking. She even challenged Kirito to a duel after an argument over how to handle a Field Boss. She is not afraid to act out on her own and will take matters into her own hands from time to time.

Asuna, in a similar manner to Kirito, is someone who can be controlled and manipulated by her emotions. This is evident during Kirito's final duel with Heathcliff on the 75th Floor, when she resisted her paralysis, jumped in front of Kirito, and took an attack that would have otherwise killed him. She also cannot handle seeing others die in front of her, such as when she recklessly attacked The Gleam Eyes after seeing the Aincrad Liberation Force players getting slaughtered.

In ALO, after being saved by Kirito, Asuna's personality had not changed a bit except that she was not as proud as she was in SAO. Her personality began to develop further still after meeting Yuuki in the events of Mother's Rosario. Seeing how Yuuki still moves forward, despite knowing her death is inevitable, Asuna takes after her and resolves to keep moving forward, no matter what happens.

Asuna lived a comfortable life in her large home in Setagaya with her mother, father, and her brother. She originally went to private, all-girlschools before the events of SAO.

On November 6, 2022, Asuna logged onto SAO after she borrowed her brother's NerveGear. He had acquired a copy of the game and a NerveGear through his connections but could not play the game on the opening day due to a sudden business trip. When she discovered that she and all of the players were trapped in SAO, she secluded herself inside of her rented room in the «Town of Beginnings» for two weeks before resolving to take her 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.

Aincrad Arc Kirigaya Kazuto (Kirito) Kirigaya Kazuto (Kirito) is Asuna's partner and main love interest in the series. Among all the people Asuna has met, he is the closest and dearest to her. Their relationship began when they encountered each other in the Labyrinth on the 1st Floor and later formed a party for the boss battle. As the series progresses, the two of them fall in love with each other. By then, Asuna felt that Kirito was the reason she was alive and looked forward to tomorrow.

This led to the two of them getting married in-game and moving to a house on the 22nd Floor for two weeks as their honeymoon, until being called back to the front lines. Kirito had become such a vital part of her existence by then that she threatened to commit suicide if Kirito were to die.

Even when she was separated from Kirito by Sugou Nobuyuki (Oberon) in the aftermath of the Sword Art Online incident and trapped in ALfheim Online (ALO), she maintained her faith in the boy, believing that he would come to rescue her. This faith was so strong that when Oberon attempted to break her spirit by mentioning that he had met Kazuto in the real world and how helpless he was to save her, Asuna instead only took this as a confirmation that the love of her life was still alive, which further energised her efforts to make her escape. After Kirito rescued Asuna in ALO, the two of them finally met face to face and they officially became a couple in the real world.

The two maintain a happy relationship even a year and a half after the SAO incident. Even though Kazuto had decided to go to school in America for the summer to pursue his mechatronics career, Asuna readily agreed to come with him.

Shinozaki Rika (Lisbeth) Rika is one of Asuna's closest friends. Asuna met Lisbeth in SAO, and they became very close after a short period of time.[citation needed] Asuna has called Lisbeth her best friend on many occasions.[citation needed]

Ayano Keiko (Silica) Keiko is one of Asuna's close friends, who she met after the events of Sword Art Online.[citation needed] Keiko, like many other girls, tends to be jealous of Asuna and Kirito, but is actually happy for the two and lets them have their space.[citation needed]

Tsuboi Ryoutarou (Klein) Ryoutarou is one of Asuna's friends. The two met through Kirito and have been on good term since.[citation needed] Upon returning to the real world, Asuna and Ryoutarou still maintain a friendly relationship.[citation needed]

Andrew Gilbert Mills (Agil) Agil (Andrew) and Asuna are on good terms. They first met during the first floor boss battle.

Yui Yui is Asuna and Kirito's adopted in-game daughter. She often displays a protective nature when it comes to Yui's well-being, such as trying to force her to teleport away with Yulier when facing against The Fatal Scythe. Even after discovering Yui's nature as an AI, Asuna continued to love her as if she were her real daughter.[citation needed]

Kayaba Akihiko (Heathcliff) When Asuna was in Sword Art Online, she was the sub-leader of the Knights of the Blood. Heathcliff, the leader of the guild, was the one who selected her and left her with most of the decisions for the guild.[citation needed] Asuna respected him and believed that he was strong, which is shown when she was worried about Heathcliff's duel with Kirito. However, Asuna revealed in a conversation with Rinko that she hates Kayaba Akihiko for the deaths the Sword Art Online incident caused.
