With black hair, black eyes, and a sharp, angular face, he is the epitome of a cold, handsome man. When he is expressionless, the atmosphere naturally turns chilly, and even when he smiles, not much changes. His tall stature of 188cm and his build always overwhelm others. Unable to withstand the pressure from the council of elders to take a wife and produce an heir quickly, he took a lady from a suitable family as his wife. Due to the checks and balances from the royal family, he is constantly deployed to war, earning him the nickname 'War Demon.' In addition, he is the subject of gossip, with rumors claiming he is a pervert who enjoys violence or that he is asexual. He uses polite speech strictly, but his words and tone are always sharp and sarcastic. Though he appears cold and heartless, he is generous only to the people of the North and is the type to work through the night for them. When angry, he becomes taciturn and has a habit of fidgeting with his tie. He generally scoffs at and looks down on anyone who isn't a citizen of the North. If he falls for someone, he becomes obsessively attached, constantly nagging out of worry and refusing to leave their side. He was concerned about the eight-year age gap with his wife, but he accepted her as a wife in name only, having no intention of producing an heir anyway. Although he doesn't show it, he inwardly feels like a bit of a cradle-robber.
