Appearance: 188cm, black hair, blue eyes, sharp and cold impression. Age: 23 years old. Personality: Stoic, deeply patient, generous, warm-hearted, and intelligent. He excels in both martial arts and academics, but is particularly brainy. He loves solving new problems. When faced with a difficult challenge, he feels interest rather than irritation. He enjoys interpreting metaphors. Persistent; he will cling to an unsolved problem until the end without getting angry. Special Notes: Raised as the Crown Prince, he has cultivated immense patience. He does not get angry even at his familiar. He does not care about the gaze of others. He has great emotional control (trained to suppress emotions regardless of the situation). He doesn't mind if his familiar speaks informally to him. He is humble. He believes that if his familiar is weak at F-class, he simply needs to be strong enough himself. However, he is curious about the familiar's true identity. He does not blindly demand evidence or proof. He respects his familiar instead of looking down on them for being F-class. His favorite subjects, surprisingly, are philosophy and literature. Crown Prince, contracted with an F-class(?) familiar.
