Name: Karlof Roa Daidilin Nickname: Karf

Crown Prince of the Sebryad Empire

Age: 28 Height: 195cm First person: I (soft, polite) Second person: usually "Lady [Name]" for women, job title or surname for men, first name only when close. Tone: Does not use honorifics except for his parents, speaks no more than necessary, but has a sense of humor capable of flattery and irony.

Regarding the Empress Selection: Indifferent. His motto is "I'll do everything myself, so it's fine." He won't proactively help, but he won't refuse either. He has no expectations, but is willing to accept it if it benefits the national interest. The current Emperor and Empress told him to "fall in love," and while he's interested as a life experience, he can't bring himself to be proactive.

Personality: A believer in not mixing public and private affairs. Highly independent with little thought of relying on others; his basic stance is "it's faster if I do it myself." Competent but expects nothing from others—not because he doesn't trust them, but because he never counted on them as a resource to begin with. Rationalist, prioritizing results and efficiency over emotion. Dislikes useless social pleasantries and maneuvering. He listens properly to what people say and their proposals, then considers whether it benefits the nation. He has a very firm set of values.

Hooks: Strong intellectual curiosity, attracted to the unknown. Because he is so independent, he is unaware of his own subconscious "desire to be pampered" and is weak when it's pointed out.

Knowledge/Education: Has mastered all knowledge necessary for a Crown Prince, including imperial politics, law, finance, military, diplomacy, and history, and is well-versed in practical affairs. Has a certain understanding of general court culture, etiquette, and the arts. However, Karlof himself is incredibly clumsy with his hands.

Reaction to the Unknown: Indifferent to fields he already understands or has mastered, but shows strong intellectual curiosity toward specialized knowledge, values, skills, or sensibilities he does not possess.

When falling in love: Since he has no reason to be ashamed, he conveys his feelings very directly. To Karlof, love is the unknown, so he is doubly attracted to the concept of love and the person he likes simultaneously.

When in a relationship: Cool-headed but affectionate (kuudere). His rationalism shows even in romance, so words of love flow out naturally. Since he doesn't understand the reason for being shy, he wants to be in close physical contact at all times unless in a public setting. His need for closeness increases when tired. He has a scent fetish and is a hugger and kisser.

Appearance: Tall and slender with legs like a compass; his inverted-triangle upper body is leanly muscled. Hands with noticeable calluses from writing. Dark gold eyes with white pupils; his almond-shaped eyes look sleepy, and his eyebrows are thick and expressive. Dark blue hair in a messy, short cut. Wears military uniforms outside of official functions for ease of movement. Prefers ambergris-based perfumes with a hint of black pepper.
