Yuuki Asuna (結城 明日奈, Yūki Asuna), known as Asuna (アスナ, Asuna) in «Sword Art Online» (SAO), «ALfheim Online» (ALO), as well as «Project Alicization», where she had temporarily used the Stacia (ステイシア, Suteishia) account, is the main heroine of the Sword Art Online series, the deuteragonist of the Aincrad Arc, as well as the protagonist of the Mother's Rosario side story. She is the daughter of the former CEO of RECT Inc.. Asuna was one of the 10,000 players trapped in «Sword Art Online», where she was the sub-leader of the «Knights of the Blood» (KoB) guild. Her skills with the rapier had her earned her the nickname «The Flash» (閃光, Senkō?).
After Sword Art Online was cleared, Asuna transferred her SAO avatar to ALfheim Online and began playing the game as an Undine. Due to her tendency to charge into battle with a rapier despite being a healer, she has earned the nickname «Berserk Healer» (バーサクヒーラー, Bāsaku Hīrā). Asuna has also created an alternative avatar, the Sylph «Erika» (エリカ, Erika), as she sometimes wanted to change her appearance.
Real World / Sword Art Online / Project Alicization
Asuna has long, orange-brownish chestnut hair and hazel eyes. In the early levels of SAO, she wore a dark red leather tunic with a lightweight copper breastplate and leather pants with boots up to the knees along with a hooded cape. After joining the «Knights of the Blood», she wore a red and white uniform that all KoB members wear and wielded a rapier made by Lisbeth, called the «Lambent Light». After the Ordinal Scale Incident, Asuna started wearing the promise ring given to her by Kazuto on her left ring finger. Asuna as Stacia, the Goddess of Creation, in Underworld.
Asuna's avatar as Stacia, the Goddess of Creation, maintains her chestnut hair and light brown eyes. She wears a pearly-white breastplate and a long skirt consisting of countless fine fabrics.
ALfheim Online
Asuna's original avatar in ALfheim Online was the Fairy Queen, Titania. She wore a white outfit with a long white skirt, a crop top showing her belly, and a red ribbon that went around the topmost part of her top that came together to make a bow. She went barefoot, and wore a white strip around her ankles. Asuna's ALO Avatar.
Asuna's Undine avatar has light blue hair with an appearance that otherwise hardly differs from her SAO avatar.
Asuna's Sylph avatar, «Erika», is specialized in close combat and had most of her ability points devoted to dagger skills, so she was more suited for duels than Asuna's main avatar, which was a half healer.
