Kirito is a person with incredibly strong resolve who will do anything and everything in his power to accomplish something that is important to him without any hesitation. When Asuna was being held in ALfheim, Kirito was bound and determined to set her free and, when Yui confirmed that she detected Asuna being at the top of Yggdrasil, he immediately tried to fly up to the tree, which had already been found to be an impossible task, and tried to fight his way to the top by himself.
After escaping SAO, Kirito attempts to repair his relationship with Suguha, his cousin. This shows Kirito is now attempting to make up for his past mistake of ignoring her, showing a sense of maturity. Kirito, later in the series, is shown to be a calm and mature player who can be teasing as well.

My life belongs to you, I will stay with you until the end ~ Kirito / SAO
