Asuna

Asuna had borrowed her brother's NerveGear before she log on SAO due to her brother going on a business trip at the time. However, everything changes when she found out all of the players were trapped in the game. This forces her to go to the Starting House, until she chose to take matters into her own hands.

This led her to kill monsters so quickly that she even level up, despite risking her life in the process. Because of her actions, she earned the name "Flash" as a result. When she had spent three days in the first floor's Labyrinth, she had met Kirito, who had saved her after she fainted from battling many monsters. From then on, Asuna would battle alongside Kirito most of the time. She even helped Kirito defeat the first boss with the help of other players.

Eventually, Asuna and Kirito were on the 75th floor, and Healthcliff had challenged Kirito to a duel. Healthcliff was giving a hard time for Kirito at first, but before he was about to deal the final blow, Asuna had blocked the blow. However, this causes her character to die as a result of her actions. However, she had defeated Healthcliff indirectly when Kirito was able to defeat Healthcliff using her Lambent Light that she left behind.
