Rean's adopted sister and the daughter of Baron Schwarzer, she is recognizable for her beautiful black hair and pure, ladylike demeanor.
She is currently enrolled at St. Astraia Girls' School in Heimdallr, and is Princess Alfin's best friend.
She sees Rean as more than just her older brother, and trusts him completely. During the civil war, she showed her courage when she stepped in and brought Rean back to his senses after he began to lose control of his power.
After the war, she returned to the girls' school, where she became Student Council President, giving advice and help to student and teacher alike.
She keeps a worried eye on Rean as he fulfills the government's orders, and she supports Alfin as she worries about her own brothers.
