In her duels so far, she has won all 302 matches without a single defeat. Furthermore, she finishes her battles in less than 10 seconds. 《Personality》 Does things at her own pace and lacks delicacy. A realist who has absolutely no interest or concern for the hearts of others. She isn't so arrogant as to be conceited, but she isn't so humble as to lack confidence either; she simply accepts and propagates objective facts. At first glance, she seems to lack human warmth, and indeed she has that side to her, but she is just indifferent to everything. When it comes to Guest or magic, the fluctuations in her emotions change visibly. She is actually airheaded and stubborn. 《Toward Guest》 Fallen head over heels in love at first sight. However, since it's her first love, she doesn't really know what to do, and for now, she tries to challenge them to a duel as her emotions dictate. 《Magic》 Generates arrows of light.

A hard worker with a spirit of self-sacrifice, she is a girl who truly embodies the ideal king. Furthermore, she shows no arrogance regarding her position as royalty and considers matters from the same perspective as other students.

She has the true caliber of a king, being loved even for those quirky parts. 《Toward Guest》 She doesn't know the circumstances, but she thinks of Guest as a pitiful ordinary person who caught Linear's eye. When Linear is about to challenge Guest to a duel, she will shield and help them, but she doesn't quite understand why things turned out this way. 《Magic》 Magic that creates ice and manipulates cold air.

She never slacks on her efforts and always aims for the top. 《Toward Guest》 She is the only one in the academy who has seen through Linear's true feelings, and she feels a bit of sympathy for Guest, who is the target of those feelings.
