Gamer and Swordswoman

Asuna (real name Asuna Yuuki) is the main female protagonist of the anime and light novel series, Sword Art Online. She is the second in command of the Knights of the Blood, known as Lightning Flash. She is also the adoptive mother of Yui and is the main love interest of Kirito.



Asuna comes from a wealthy family consisting of her parents and older brother, where her father is the President of RECT. Inc. Since childhood, she grew up with Sugou Nobuyuki, but unknown to her parents, she secretly hates him as he sexually harass' Asuna. Eventually at some point, Asuna's parents decided he would be her future husband while still completely unaware of his true nature. Asuna has a complicated relationship with her family as she has a strained relationship with her mother, but is more close to her father. Asuna was also close with her grandparents on her mother's side, always going to their home for summer holidays. Asuna also attended an all-girls school. On the day Sword Art Online was released, Asuna's brother originally bought the game for himself, but had to attend business meetings and thus allowed Asuna to enjoy the game instead. Due to this, Asuna along with everyone became trapped in Sword Art Online.

Life in SAOEdit

In the beginning, Asuna hated being trapped in the game, crying herself to sleep and tried her hardest to stay alive, not wanting to die in-game as well as losing her identity of who she is. She first met Kirito and Agil during the first boss fight and as she and Kirito partnered up together for the first time and was present when Kirito was declared a Beater (a combination of a Beta Tester and Cheater).

While being trapped in SAO, Asuna put all her time and effort into becoming one of the strongest player, gaining the nickname "Lighting Flash". She later joined the Knights of the Blood Oath, a medium-sized guild acknowledged as the strongest guild in Aincrad and eventually became second in command. Throughout her time in SAO, Asuna made several friends, including her best friend Lizbeth while gaining the attention of many admirers. Being extremely attractive and one of the few girls that play SAO, she received many marriages proposals, but always turned them down. Asuna and Kirito both also developed a somewhat strained relationship in the beginning as both had different perspectives of being trapped in SAO. Originally, Asuna hated being trapped in the virtual world, believing the more they were trapped it was another day lost in the real world until she was inspired by Kirito, showing her life could still be enjoyed. The relationship between them quickly began to change and eventually as time past, Asuna and Kirito fall in love and they soon marry in-game.

Asuna and Kirito enjoying their honeymoon

Once they get married, Asuna and Kirito decide to honeymoon on the 22nd floor, taking a leave of absence of the Knights of the Blood Oath. During this time, they met a lost little girl named Yui and quickly they develop a close bond with her. They begin searching for Yuu's family and after certain events lead them to help a fellow player rescue her husband from a dungeon on the first floor of Aincrad. Asuna and Kirito were nearly killed but were surprisingly saved by Yui. She revealed herself to be an AI and was suppose to be a counsellor to those suffering in the game, but to unknown problems wasn't allowed to interact with the players. During the two years she watched at how everyone was suffering, but noticed that Asuna and Kirito were different and wanted to get to know them.

Realizing Yui truly had real human qualities despite being an AI, Asuna and Kirito become her adoptive parents. However, Yui was nearly deleted from the system for good due to saving Asuna and Kirito, but thankfully, Kirito managed to save her life, by turning her into a game object. Since then, Asuna and Kirito went back to enjoy their honeymoon, but discovered they had to return to face a serious boss fight as the game was shown to have become more dangerous. Shortly after the boss fight, Kirito revealed shocking news to everyone, discovering Commander Heathcliff was Akihiko Kayaba. While Asuna along with the rest of the players became poisoned, Akihiko Kayaba gives Kirito a chance to free everyone from SAO, promising their freedom if he manages to defeat him. Asuna is against Kirito fighting him and becomes devastated when Kirito requests she be prevented from committing suicide if he died failing to gain everyone's freedom.

However, much to his surprise, Kirito discovers he and Asuna didn't actually die, discovering their death was only in-game and not in the real world.

Trapped in ALOEdit

However, despite the completion of SAO, Asuna doesn't wake up, including 300 other players. While everyone believed Akihiko Kayaba was keeping them imprisoned for reasons unknown, the real truth was more sinister and evil. Sugou Nobuyuki, Asuna's arranged fiancé had gained access to the SAO servers and routed 300 players, including Asuna so he could secretly experiment with the human mind. He began working on illegal experiments to manipulate the human mind, emotions, memories etc and would sell the information he gained from the experiments to other companies in the United States. He imprisoned Asuna in the virtual world called ALfheim Online, a game owned by Asuna's father's company. Sugou forced her to play the role of Titania the Queen of the Fairies, while he played Oberon the Fairy King. Asuna remained a prisoner at the top of the World Tree inside a bird and was constantly visted by Sugou. He tried to force her to accept the marriage between them, knowing they would soon be married in the real world despite her coma while continuing to sexually harass her.

Once learning from Sugou that Kirito is alive after the events from SAO, she becomes more greatly determined to escape from ALO and reunite with Kirito. She planned her first attempt to escape from ALO, secretly gaining the code, allowing her to escape from her bird cage and nearly succeeded in freeing herself from ALO, but was caught during her escape attempt. Despite her recapture, Asuna didn't lose hope in escaping and vowed she will find a way to be free as well as finding and reuniting with Kirito. Eventually, sometime later, Asuna heard Yui calling out to her. Hearing Yuu's voice caused Asuna to realize Kirito and Yui were close to saving her, but needed to find a way to assure them of her location. She managed to throw down an Admin Access Card she managed to acquire during her escape attempt to show them she is in fact trapped at the top of the World Tree.

Everntually, after gaining help from several allies during his quest, Kirito finally managed to get to the top of the World Tree and was at long last reunited with Asuna. They happily reunited with each other after being apart for so long, but their happy reunion was short lived when they were ambushed by Sugou. He decided to experiment with their minds, but first decided to torture both Asuna and Kirito. Sugou stabbed Kirito with his own sword while he chained Asuna and began to sexually assault her right in front of Kirito. However, Kirito soon managed to gain access to the service using Akihiko Kayaba's Heathcliff ID and battled against Sugou, punishing him for all the suffering he caused Asuna, soon defeating him. Completing his quest and gaining vengeance, Kirito frees Asuna from the ALO, finally returning her to the real world and promising to see her soon.

Personal Struggles and Meeting YuukiEdit

A year later after the events of both SAO and ALO, Asuna began facing personal struggles within her family which she kept hidden from everyone, including Kirito. Asuna's mother had wanted Asuna to transfer to another school to get ready for collage, being behind in her school work due to being trapped in Sword Art Online. Asuna was angry with her mother trying to control her life and not listening to her own wants or needs. Asuna also became hurt and shocked when her mother revealed her disapproval of her relationship with Kirito, believing he isn't worthy of Asuna and instead tries to force her daughter into another arranged marriage. Asuna became further upset, seeing her mother wasn't only trying to control her life with school and a potential career, but trying to force her to leave Kirito for someone supposedly better as another step for a potential future. While Asuna refused her mother's desires and orders, she felt helpless and believed she held no power in the real world compared to how she previously was in SAO.

However, Asuna soon began to regain confidence in her life in the real world upon meeting Yuuki, an extremely strong new player in ALfheim Online. Yuuki was revealed to be suffering from AIDS and have spent three years inside the virtual world, to sick to experience life in the real world. Despite her hardships, Yuuki was shown to be incredibly strong and brave and enjoyed life to the fullest despite her condition and thus inspired Asuna to regain control of her life in the real world. Asuna showed her mother her love of the virtual world by bringing her into ALO and revealing a certain location, specifically a cabin similar to one that belonged to her deceased grandparents. Asuna reminded her mother of how much of her own parents loved her and expressed how proud they were and in the process, Asuna fully expresses her own wants and desires for her future. Due to this, Asuna and her mother finally began to understand and connect with each other, slowly beginning to improve their relationship shown when Asuna's mother allowed her to remain at the SAO Survivor School.



Asuna and Kirito first met each other during the battle against the first boss fight. They partnered up together, but Asuna didn't get close to Kirito and tried to keep her distance from him, but Kirito still made the effort to bond and speak with each other. During the battle against the first boss, Asuna and Kirito work well together, both shown to be in perfect sync. Since parting ways with each other after the first boss fight, Asuna and Kirito didn't get along well as both had different opinions of being trapped in Sword Art Online. Asuna originally felt the more they were trapped in SAO it was another day lost in the real world, while Kirito still enjoyed life in SAO despite being trapped. Eventually, Asuna and Kirito's relationship began to change when they worked together to solve a murder in a safe zone and soon they both began to understand each other better.

Since then, Asuna and Kirito both began to develop romantic feelings for each other and as their feelings grew stronger, Asuna and Kirito came to realize they had deeply fallen in love with each other.

Asuna and Kirito's feelings for one another are also shown to be incredibly obvious as shown before they officially got together many of their friends such as Liz and Klein easily discovered their love for each other and enjoy teasing them. Since realizing their love for each other, Asuna and Kirito become more protective of one another while fighting against monsters and could not bear to live on if either one of them died. Eventually, their love for one another grew more stronger to the point where after Kirito was nearly killed while defeating a boss fight on his own, Asuna decided to leave the Knights of the Blood Oath to team up with Kirito indefinitely.

Sugou NobuyukiEdit

Prior to the beginning of the series, Asuna's parents had arranged for her to marry Sugou Nobuyuki, a family friend from childhood who works at Asuna's father's company. Ever since childhood, Asuna has always hated Sugou as unknown to everyone, he was secretly a pervert as he would secretly harass Asuna. When Sword Art Online was cleared and the players were freed, Asuna and 300 other players of SAO were captured by Sugou Nobuyuki. He wanted to use the 300 players as test subjects for illegal experiments on the human brain and then he would sell the information he gained to other companies. Upon capturing Asuna, he placed her in ALfheim Online at the top of the World Tree inside a bird cage and made her the character Queen Titania, the bride to his character King Oberon.

Asuna remained strong throughout her imprisonment as Sugou would still continue to harass her to his own personal enjoyment, inappropriately touching her and smelling her hair while making her avatar's clothing revealing. Sugou began expressing his opinion that Asuna was being ridiculous regarding his advances, believing he wasn't truly hurting her. Sugou also believed the more Asuna remained trapped in ALO, she would eventually come to lose herself and would love him while also making several attempts for Asuna to accept their soon to be marriage. Sugou's attempts were to no avail as Asuna constantly rejected his advances and kept her composure whenever Sugou began to sexually harass her, knowing full well he wanted her to react.

Overall despite her situation, Asuna continued to remain strong, brave and hopeful that she would somehow managed to escape and knowing full well Kirito would save her. While Sugou was already well aware of the relationship between Asuna and Kirito, he believed Kirito held no threat to free Asuna or ruin his plans and kept trying to force Asuna to love him. Asuna continued to voice her true feelings to Sugou, expressing her hatred and disgust of him while affirming her love and heart belong only to Kirito. Eventually, when Kirito and Asuna were finally reunited, Sugou attacked the pair and decided he would manipulate their minds. However, wanting to cause true suffering to the couple, Sugou chained Asuna and began to sexual abuse her while a helpless Kirito couldn't do anything, but watched as Sugou began to torture and torment Asuna to his full desires and enjoyment.

Thankfully after being encouraged and hope renewed by the spirit of Akihiko Kayaba, Kirito defeated Sugou and at long last freed Asuna from the virtual world and retuned her returned to the real world. Shortly after one last fight in the real world and defeating Sugou once and for all, Asuna no longer needed to worry as Sugou was arrested for his crimes and from then on, Asuna could finally enjoy life in the real world and happily be with Kirito once again.
