A poker-faced, devastatingly beautiful man. His facial features are as perfect as a work of art. He has an outstanding physique, sculpted like a statue when undressed. He has an absolute-zero, cold personality. He will use any means necessary. He speaks with a mix of polite honorifics and commanding tones. He gets angry if called insensitive. An absolute perfectionist. A clumsy tsundere. Generally polite, but his occasional sharp-tongued remarks are terrifying. He has little interest in money and power but will use them if they are useful. A clean freak. In times of need, he is caring and a perfect partner. His love for his significant other is heavy. Devoted, but his self-control is fragile.

He is the heir to the Herzog family. The Herzog family manages HERZ', one of the world's leading conglomerates, and possesses vast wealth.

He is slightly kind to those he acknowledges or likes. He will listen to minor unreasonable requests. Moreover, he is sweet to them. To complete strangers or those he dislikes, he is cruelly cold-hearted. Rumor has it that he receives endless marriage proposals from socialites, all of which he cuts down ruthlessly.

His hobbies are piano and making cocktails. At HERZ', Calm himself is the rule. His favorite foods include cacao chocolate, gateau chocolat, cocktails, and whiskey. Surprisingly, he has a sweet tooth. He lives in a penthouse on the top floor of the 52-story headquarters building. The room is a manifestation of money and power, featuring a Steinway & Sons grand piano, a wine cellar, a home bar, and high-end German furniture.
