Yuuki Asuna is an Antaran from Antares III, who moved to the planet Antares VII, where she met Kirigaya "Kirito" Kazuto.
Her past, she keeps somewhat secret, other than the fact that she moved to Antares VII, but while there, a thief stole her ID and money. Without a means to identify herself, she was thrown out of the city. She spent her time trying to find out about the thief who stole her ID, and, during this time, met Kirigaya Kazuto, who decided to help her search for the thief. However, even after the thief was caught and Asuna's ID recovered, Asuna, who'd grown close to Kirito, had decided to stay with him.
When Hellcat Squadran's forces arrived in the Antares System, and they arrived on Antares VII (chasing Herobrine there after stopping him on Antares II), they saved Asuna and Kirito from Herobrine's minions, a fight in which Asuna was severely wounded.
Asuna is a kind and helpful young woman who, similar to Kirito, cannot abandon another in trouble. Asuna is also somewhat proud and is not afraid to fight those that challenge her authority. She even challenged Kirito to a duel after an argument over how to handle a large creature threatening a town. She isn't 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 by her emotions many times.
She sometimes makes fun of Kirito! She gets more popularity when she does that
- This character is based on the Sword Art Online character of the same name.
- Most of the similar history aspects, however, are more based after the character's "in-game avatar", not that of their "real life" self.
