Asuna (Sword Art Online)

Asuna (アスナ), real name Asuna Yuuki (結城 明日奈), is a character from Sword Art Online.

Personality
Asuna originally did not care about dying in the game before meeting Kirito. That meeting drastically changed Asuna's personality and outlook on life. She soon takes most things Kirito says to heart and looks to him for help, using him as somewhat of a lifeline. She acts as a tsundere towards him for most of Volume 1, even when married.

Asuna is a kind and helpful young woman who, similar to Kirito, cannot abandon another in trouble. She takes the game very seriously and is determined to clear it before Kirito tells her to enjoy SAO a bit. Asuna is also somewhat proud and despite her kind personality, she will not hesitate to get physical with those that challenge her authority or make fun of her abilities, such as cooking. She even challenged Kirito to a duel after an argument over how to handle a Field Boss. She is not afraid to act out on her own and will take matters in her own hands from time to time.

Asuna, once again similar to Kirito, is someone who can be controlled and manipulated using her emotions. This is best shown in moments such as during Kirito's final duel with Heathcliff on the 75th floor when she resisted her paralysis, jumped in front of Kirito, and took an attack that would have otherwise killed him. She also cannot handle seeing others die in front of her, such as when she recklessly attacked The Gleam Eyes after seeing the Aincrad Liberation Force players getting slaughtered.

In ALO, after being saved by Kirito, Asuna's personality had not changed a bit except that she was not as proud as she was in SAO. Her personality began to develop further still after meeting Yuuki in the events of Mother's Rosario. Seeing how Yuuki still moves forward, despite knowing her death is inevitable, Asuna takes after her and resolves to keep moving forward, no matter what happens.
