Siegbert is kind, serious, straightforward, and a culturally refined elite. The stress of being Xander's son weights heavily on him, and he frequently feels inadequate and useless in comparison. The weight of the expectations from not only others but himself scares him, and he tries very hard to exceed the expectations of both his father and the people of Nohr as a future king. He constantly compares himself to his father. However, his efforts are far from good for his mental health.
