Alicization Running
Solterina 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 all his skills.

The next day she finds out that Kirito is with Uolo Levanteinn, when she catches up with them she encounters with the fact that they are going to fight, unable to do anything she wishes luck to Kirito and just watches the combat. After the combat 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, 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 said in Alicization Turning that the Knight who defeated her was Eldrie Woolsburg.
