Sue

Suelecia Analeit, known as Sue, is Schlain's younger half-sister, and the second princess of the Kingdom of Analeit. She is a genius equal to Schlain even though he has the advantage of knowledge from his previous life. 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 personality. Sue has expressed her intense dislike towards Karnatia ever since her young age. This is due to Schlain and Katia's relationship as best friends in their previous life, which, to Sue, looks like a budding romantic relationship between the two.
