Nickname: Asuna
Known as: The Flash

Asuna is a friend of Kirito and is a sub-leader of the guild Knights of Blood (KoB), a medium-sized guild of about thirty players, also called the strongest guild in Aincrad. Being one of the few girls that play SAO, and even more so that she's extremely pretty, she receives many invitations and proposals. She is a skilled player earning the Title "Flash" for her extraordinary sword skill. The KoB has assigned her two bodyguards, one of whom despises Kirito. Her game alias is the same as her Real World name. She later on falls in love with Kirito about a 6 months into the game, eventually leading to them being married in-game . In real life, she lived a very stressful life, forced to live up to the high expectations of her parents. She felt that she would live her life following her parents rule, and never once went against that idea. But after living in SAO and meeting Kirito, she gain more emotions and realized what it was like to actually live, and looks back on her past with disgust. She has a very strong will, able to sacrifice days of sleep to level up. After Kirito defeated Heathcliff, she was supposed to have been freed but instead she was imprisoned in ALfhiem Online and forced to play the role of Titania the Queen of Fairies, by Nobuyuki Suguo who similarly played the role of Oberon the Fairy King. This was done so that Nobuyuki Suguo could marry Asuna in the real world, while she was unconscious, and thus take over RECTOR Progress Inc. She constantly tries to get out of the World Tree where she is imprisoned and escape going so far as to steal a GM card which she throws out of the window when she hears Yui's voice.
