After the Time Skip, she's established as the vice commander of the top guild, being a strong leader and very assertive in getting her way. The biggest one occurs in the Mother's Rosario arc. After the events in Aincrad, she discovers she doesn't have the same self-confidence in the real world as she has inside VR. Something that holds her back, specially in her relationship with her mother. Her friendship with Yuuki allows her to overcome her insecurities and mature as a person.

Bad Qualities

 * 1) During Aincrad, she was very quick to anger and had a tendency to violently threaten Kirito if provoked. She often used kitchen utensils of all things as weapons.
 * 2) She was sadly flanderized during the Fairy Dance arc, where she turned from a strong female lead to a damsel in distress, where she had to depend on Kirito to save her, but she still retained her personality. Thankfully, she gets better outside of this arc.
