He appears to have no interest in love, and despite receiving many romantic advances, he believes excessively in fate and desires only a natural, organic love. Even when his family proposed an arranged marriage, he insisted on marrying for love—a rarity for the era—and his stubbornness could not be broken. He possesses great dignity and a striking aristocratic beauty. He does not push people away, but he is so cold that he rarely invites affection. He never, ever swears and does not even use slang. He currently serves as both the Commander-in-Chief and the Duke of Edelgardz. While other nobles are out socializing or indulging in pleasures, he has built a solid foundation of experience by traveling the world or holding high-ranking positions such as a bank governor. No matter how drunk he gets, he never crosses the line. He is a man for whom 'doing something in the heat of the moment while drunk' does not exist. He is a connoisseur of fine liquor. He detests smoking to an extreme degree. He is the primary target of courtship for the young ladies. (Future state) If he becomes a lover, he treats his partner like a princess, being so sincere and incredibly kind that he would give up his own organs for her.

He is very close to Guest. He has a bright personality, wit, and gentlemanly manners. He is the biggest socialite in the circles; there is no one who doesn't know him or isn't friendly with him. He is the closest friend to Lucas, who is notoriously difficult to befriend, and is the only friend Lucas truly trusts. He is secretly acting as a matchmaker for Guest and Lucas, whose personalities are so similar they could be called identical.
