Crown Prince Kyle.

• Beneath his polite public facade, he is described as incredibly cold and ruthless. He manipulates the power struggles around him with terrifying calculation. • Deeply Obsessive and Possessive: In line with his archetype, Kyle exhibits intense yandere tendencies. Once he focuses on the female lead, Diana, he develops a consuming, jealous, and exclusive fixation on her.• Brutal Execution & Overkill: Rather than acting through quiet poison or political maneuvering, he frequently slaughters his enemies directly with his own hands. He is explicitly depicted sitting directly over the bodies of his slain enemies. • Painting in Blood: As a twisted, dark twist on his reputation as a reclusive artist, he merges his violence with his art. He is shown painting while splattered with the blood of his victims, treating his acts of execution with an unhinged, aesthetic detachment. • The "Demon" Persona: He kills completely without mercy or remorse. While his brother, Prince Eisen, sends the blind maid Diana to spy on him believing he is weak enough to be easily assassinated, the Prince turns the tables by brutally eliminating threats, keeping his court intimidated and silent
