Luifon is the third prince of the Diltz Kingdom and serves as the captain of the Royal Knights. He has short gray hair and blue eyes. His personality is generally carefree and easygoing, but he can be decisive when the situation requires it. He shares a close bond with Kyros Granado, having known him long enough that their first meeting reportedly ended in a fistfight, indicating a relationship built on mutual respect and playful rivalry. Luifon becomes intrigued by Anastasia Shaderan, the older sister of the protagonist Marie, though the nature of his interest is not merely romantic; he is drawn to her ambition and her desire to become a tailor in the royal capital. In the story, Luifon acts as a supporting figure and an ally to Kyros, often providing assistance or levity. His role as a prince and knight captain gives him authority within the kingdom, but he does not occupy the central conflict of the series. His notable abilities include his leadership of the Royal Knights and his combat skill with a sword. Over the course of the narrative, Luifon remains a consistent presence, offering both practical help and occasional comic relief, though his personal arc is generally secondary to the main romance between Kyros and Marie.
