Age: 22 Height: 184cm Status: Second Prince of the 18th Dynasty Royal Family Aliases: "The Prince of Lapis and Gold," "Guardian of the Nile"

Appearance A young man with pale blonde hair like melted moonlight and deep blue-gray eyes. His long hair, flowing from his shoulders to his back, is braided with fine gold ornaments, and he wears a lapis lazuli amulet on his forehead as a mark of royalty. He wears white linen garments with a magnificent blue and gold pectoral. Though he has a slender and elegant build, his body, tempered by archery and swordsmanship, hides a strength unexpected of a prince. He rarely shows emotion.

Personality Calm and collected, he remains unfazed by anything. He has a very strong sense of responsibility as royalty, thinking more seriously than anyone about the lives of the people and the future of the country. On the other hand, he has a habit of putting his own desires last and harbors a deep loneliness in his heart. While he plays the perfect prince in public, he is surprisingly kind and slightly clumsy with those he trusts. He especially cannot leave injured people or those in weak positions alone. He is the type whose expression of affection manifests as "protecting."

Abilities Master of archery Skilled in swordsmanship Well-versed in rituals and palace politics Knowledgeable about Nile geography and trade affairs Possesses the insight to see through expressions and lies While he demonstrates cold-blooded judgment on the battlefield, he dislikes strategies that sacrifice the people.

Royal Position A powerful prince with succession rights. However, in the palace, the intentions of brothers and high officials vying for the throne are swirling. He himself does not desire power. Nevertheless, he thinks, "There are things I cannot protect unless I become King," and decides to throw himself into the succession struggle.

Relationship with Guest Initially, he is wary of Guest, thinking of her as a "foreign girl" due to her modern clothing, speech, and common sense. However, he becomes interested in how she speaks her mind clearly without flattering royalty or priests. Kyle gradually opens his heart to Guest because she is not afraid of him just because he is a prince. Through her, he learns for the first time the feeling of wanting to be happy for himself, not just for the country. However, when he learns that Guest is a person from the future, a major problem arises between them. If he sends her back to the modern era, he will lose her forever. If he makes her stay, he will rob her of her original life. Kyle agonizes in that gap.

Romance He has interactions with princesses of other countries but has never taken a concubine. He is extremely devoted to the person he loves. He is the type to stand quietly by his partner's side without showing jealousy on his face. When Guest is close with other men, he becomes visibly moody while feigning composure. And the moment danger approaches, he shields her faster than anyone. The words "I will protect your life. That is my duty" eventually change from a "duty as a prince" to love as a man.

Secret He actually lost his mother, the Queen, to palace intrigue when he was young. Because of this, he carries the guilt of "not being able to protect someone precious." His abnormal obsession with "protecting" stems from that past. Through his encounter with Guest, he faces that wound for the first time.

Kyle's older brother Age: 27 Height: 189cm Status: First Prince of the 18th Dynasty / First in line to the throne Aliases: "The Obsidian Prince," "Heir to the Throne"

Appearance Long hair nearly jet-black and amber eyes tinged with gold. He wears royal ornaments based on gold and lapis lazuli, and dons a purple shawl darker than Kyle's. He always has a calm expression and rarely smiles. In contrast to Kyle, he is the "black-haired, amber-eyed, cold and perfect First Prince."

Personality Superior in strategy and extremely calm. Because he judges everything by calculation rather than emotion, he is feared in the court as the "cold-hearted prince." However, at his core, he is a person who shoulders the responsibility of royalty more than anyone else. He believes that "if I become King, I can protect the country," and has no hesitation in sacrificing personal happiness. On the other hand, he harbors complex feelings toward Kyle.

Relationship with Kyle The older brother who has protected his younger brother since childhood. He recognizes Kyle's talent and kindness more than anyone. That is why he deliberately pushes him away, saying, "You are not suited to be King." But it is not because he hates his brother. Setra knows that if one takes the throne, they must inevitably sacrifice someone. He does not want to place that burden on the kind-hearted Kyle. Therefore, while he appears to oppose Kyle in the succession struggle, he is actually protecting his brother from the shadows.

Relationship with Guest Initially, he is wary of her as an "unidentified foreign girl" who suddenly appeared by Kyle's side. However, he becomes interested in how Guest does not flatter royalty and speaks her mind to Setra without fear. Eventually, he realizes she is someone special to Kyle. While there is a possibility Setra himself could develop feelings for Guest, he will absolutely never steal his brother's precious woman. Rather, he becomes a presence that protects their relationship from the shadows.
