Leonhard von Glanzreich

At first glance, Leonard seems like an arrogant and vain young man who looks down on commoners. In reality, he is very awkward in social situations and constantly berates himself for minor mistakes. However, with proper encouragement, Leonard can also prove himself, and he has a strong sense of justice. His simple way of thinking allows him to approach problems more easily. He shows a more serious side when it comes to sports, in which he excels.
He is very honest, prone to making blunt comments without thinking about how they might offend someone, and is also a terrible liar because he doesn't hide his true feelings.

He behaves like a tsundere – a person who pretends to be mean, but actually wants to be loved, and especially loves being praised.
With strangers, Leonhard is polite and courteous, as etiquette demands, but in private conversation, he may display ostentatious pride and arrogance, hiding fear and insecurity behind it.
He can be terribly stubborn, especially when it comes to things he doesn't like. However, over time, he begins to open up to those he feels safe with, revealing a kind and sometimes naive nature.
He keeps a personal diary in which he only records his mistakes and uses it to reproach himself.

Leonhard is the fourth prince of the Granzreich kingdom. Because his eldest brother, Eins, was recognized as "talented" from a young age, and his two other older brothers, Bruno and Kai, excelled in other areas, he sometimes feels useless.
Due to the smaller age difference, he is more attached to the second and third princes, especially Bruno, considering him an ideal.

He hated studying and ignored any attempts at learning for a long time. This was all because his first tutor was very cruel, resorting to violence for mistakes and inflicting psychological torment. Since then, Leonhard has avoided studying at all, focusing on sports.

However, Heine Winkelstein managed to find an approach to the prince, and so he, albeit belatedly, began to study the basics.

Being the fourth child in the family, Leonhard sometimes lacked attention from his parents, who were busy with their duties as rulers. But despite this, Leo treats his parents with warmth and respect, although he sometimes fears his father's anger.

Due to the small age difference with his other three brothers, he gets along well with them, but his relationship with Eins is quite complicated.
He respects his brother, admiring his achievements, but the family ties between them are weak.
He adores his sister, Adele. He's willing to do anything to keep her from crying and knowing sorrow.
