Tiese Schtrinen

The first female novice trainee at the Norlangarth Empire Swordcraft Academy. She is an apprentice attendant to Eugeo. Her birthday is July 2nd (Human Calendar), and she is 16 years old.

Like Ronie, she comes from a sixth-rank noble family and became Eugeo's attendant because she was not chosen by any other senior swordsman. She has feelings for Eugeo and pleads with him to become her husband by earning a title in the Four Empires Unification Tournament if he fails to become an Integrity Knight.

She and her roommate, Frenica, who is an attendant to Humbert, protest together against the humiliation Frenica suffers from Humbert. As a result, they are nearly assaulted by Raios and Humbert as punishment. She regrets that Eugeo and Kirito broke the Taboo Index to protect them and became criminals, and she vows to become an Integrity Knight in the future to rescue Eugeo.

During the War of the Underworld, she volunteers for the Human Empire Defense Army's supply unit alongside Ronie to reunite with Kirito and Eugeo. She reunites with Alice but is devastated to learn of Eugeo's death. However, she senses Eugeo's thoughts from the "Blue Rose Sword" Kirito carries and, after recovering, witnesses Kirito's awakening during the battle against Vassago with Ronie.

After the war, she and Ronie become Integrity Knight apprentices and inherit Eugeo's number, becoming "Tiese Schtrinen Thirty-Two" (though only Kirito knows this in the story). As an apprentice, she is given a young dragon named "Shimosaki" and is entrusted with Eugeo's memento, the "Blue Rose Sword," by Kirito during her formal appointment. Meanwhile, she is proposed to by Renly, who had feelings for her during the War of the Underworld, and she struggles with accepting Eugeo's death.

Later, she marries Renly and has children. She undergoes the petrification and life-freezing ritual and spends 200 years in the Cathedral with Selka and Ronie. She is awakened by Kirito and his friends upon their return to the Underworld.
