Sortiliena Serlut

Sortiliena Serlut (ソルティリーナ・セルルト) is the mentor of Kirito, during his first year in the «Norlangarth Empire's Independent Master Sword Academy», and the second-seat swordswoman at the Academy, where she is known as the "Walking Tactics Manual". She is introduced in the Alicization Arc.

Appearance
She has very long straight hair and can easily be considered beautiful. As an elite-swordswoman, she customized her uniform to a purple one.

Alicization Running
Sortiliena is doing late practicing with Kirito and they talk briefly about how much Kirito has improved since he enrolled. After a while they stop and Kirito tells her that he wants to show her his true ability, so he promises that the next day, as a graduation present, he will show her his true skills.

The next day she finds out that Kirito is with Uolo Levanteinn. When she catches up with them, she encounters the fact that they are going to spar as a punishment for Kirito, but, being unable to do anything to stop the sparring, she wishes luck to Kirito and just watches the combat. After the battle, she congratulates Kirito for his performance against Uolo, and invites him, along with Eugeo and Golgosso, to her room to celebrate.

On the last tournament before the graduation, she finally defeats Uolo using the Secret Skill «Whirl Current», that she mastered in just one month after seeing Kirito's battle with Uolo, and graduates as the top student from the «Norlangarth Master Swords Academy». Two weeks after graduating, she participates in the «Empire Swordsmanship Tournament», but lost against a Norlangarth Knight who cut her whip and sent her sword flying.

It's later revealed in Alicization Turning that the Knight who defeated her was Eldrie Woolsburg.
