Personality
Sue is extremely attached to Schlain, to the point of completely idolizing him. She developed a romantic interest to him as well as a yandere archetype personality.

Sue and Schlain spent much of their time growing up together, and due to Schlain's need to be a proper big-brother, Sue came to look up to him in almost every way. After they come of age and receive their first royal [Appraisal], Katia joins the two of them.

Later, Feirune enters their lives, attaching herself to Schlain... much to Sue's chagrin. Their lives continue without incident until Sue's other half-brother Julius dies fighting in the Human-Demon War. Schlain and her are separated.

One day, Sue meets with Schlain to visit the King regarding his status as the Hero. While there, Sue kills her father with Light Magic, framing her beloved brother for killing the King of Analeit and causing him to flee. Schlain figures out that she's been brainwashed by Hugo Renxandt. When Schlain flees Hugo takes over and placing her brother Cyris as a puppet king of Analeit.
