Asuna Yuuki

Lore & Background

Asuna is the main heroine of Sword Art Online and main protagonist of the seventh volume and the Progressive series, which tells the entire Aincrad Arc through her perspective. She is 17, a friend and later girlfriend and in-game wife of Kirito in Sword Art Online and Alfheim Online. As sub-leader of the Knights of the Blood Oath, she is one of the few women that play SAO and extremely attractive, receiving many invitations and proposals. She is strong-willed and an accomplished player known in-game as 'the Flash' for her extraordinary fast skills with the rapier. She falls in love with Kirito and they marry in-game after saving him from being killed by Kuradeel. Towards the end of the SAO arc, she saves Kirito from a killing blow by Heathcliff at the cost of her life, though her death was only in-game and she is reunited with Kirito shortly after the death of Heathcliff. In Fairy Dance, despite the completion of SAO, Asuna remains unconscious and is detained in Alfheim Online, forced to play the role of Titania the Queen of Fairies, with Nobuyuki Sugou playing as Oberon. She attempts to escape the World Tree, steals a GM card, and throws it down to Yui when Yui's voice is heard. Upon being released, she creates two avatars for Alfheim — Asuna the Undine Healer and Erika the Sylph battle character — and continues living together with Kirito. She enrolls at the SAO Survivor School with Kazuto Kirigaya in the real world. In Alicization, after Kirito disappears after Johnny Black's attack, Asuna discovers the Ocean Turtle, requests help from Rinko Koujiro, gets on board, and convinces Kikuoka to let her stay. When the Dark Territory attacks, she logs into the Underworld under the super account the Goddess of Creation, Stacia.

In Their Own Story

Asuna's signature one-handed rapier is Lambent Light. She continued to use it as her main weapon of choice until the fateful battle on the 75th Floor. Kirito used this rapier to stab and defeat Heathcliff in the final battle, thus clearing the game. Her rapier, combined with her speed, earned her the nickname 'Lightning Flash.'
