## Appearance

* IRL
* Avatar
In the real world, Asuna is an average height young woman with long, orange-brown hair that is partially pulled back into two connected braids. She has hazel eyes, and is lean with feminine features. She is surprisingly muscular from practicing her swordplay in secret. Asuna normally wears a white tank top underneath a long cream sweater with a large, red heart printed on the front. She wears black leggings underneath this sweater, and wears black flats as her shoes.

As her avatar, only Asuna's outfit changes. She wears a sleeveless, high-necked, white top with red detailing and an asymmetrical hem over a pleated, red skirt as well as white, thigh-high socks and white boots with ankle guards. She also wears high, white, fingerless gloves and a white breastplate.

## Background

### Before the SAO Incident

Asuna was born on Sunday, September 30, 2007 as Yuuki Asuna, the youngest child and only daughter of Yuuki Shouzou and Yuuki Kyouko. She was born as the younger sister of Yuuki Kouichirou.

As a child, Asuna lived a comfortable life in her large home in Setagaya with her father, her mother, and her older brother. She went to a private, all-girls school before the event that would be known as the SAO Incident.

### During and After the SAO Incident

#### *Aincrad Arc* of *Sword Art Online*

On November 6, 2022, Asuna logged into Sword Art Online 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 Aincrad, 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.

Asuna met Kirito for the first time in the meeting held to discuss the raid of the boss of Floor 1. Eventually the two of them fell in love and married in-game, later adopting their daughter Yui.

On Thursday, November 7, 2024, Asuna and Kirito helped to defeat the boss of Floor 75. After the boss was defeated, Kirito realized that Heathcliff was actually Kayaba Akihiko, the man who trapped all the players of SAO in Aincrad. Kirito engaged in a duel with Heathcliff while Asuna and the others who were present at the boss fight were paralyzed and was nearly killed by a fatal mistake, but Asuna found a way to move and took the blow that would've killed Kirito for him, dying in the process.

Both Asuna and Kirito were credited with the defeat of Aincrad by Heathcliff, and they were rewarded with their lives. All the remaining players of Sword Art Online were logged out after Heathcliff's defeat. Asuna and 300 other players, however, did not awake in the real world, instead having been trapped in the game of ALfheim Online.
