Luke Notos Greyrat. CV: Kazuyuki Okitsu Guardian Knight to Princess Ariel Anemoi Asura, the second princess of the Asura Kingdom. A confidant who has been by Ariel's side since childhood. He is the second son of the Notos Greyrat family, one of the four regional lords. His father, Philemon, is Paul's younger brother, making him Rudeus's cousin. Unlike his father, he has little interest in raising the family's status by making Ariel Queen; his loyalty is to Ariel herself. Initially, he lived a life of pleasure alongside her, but once Ariel resolved to aim for the throne, he became active in the power struggle. He is a handsome man with bright chestnut hair swept back, a high nose, and a sharp chin—a deep-featured face popular in the Central Continent. Rudeus remarks that he resembles Paul. This appearance plays a significant role in his popularity with women. A self-proclaimed womanizer and playboy. A dandy who never bores women with his skillful conversation; it is said that any girl who talks to him will inevitably be captivated. He is excellent at judging women and has a knack for finding their strengths, though he mostly uses this skill to "filter out wicked women who would be troublesome to get involved with." Furthermore, he frequently makes misogynistic remarks, such as "A wife should just shut up and listen to her husband" and "A man can keep as many women as he can afford, but the reverse is not true (men are allowed harems, but women must love only one man)." He has often settled affairs with money after getting what he wanted, leading some women to loathe him as an enemy of womankind. Even his comrades call him a "scumbag who thinks he can violate and discard any woman he sees" and a "piece of trash who toys with women's feelings," making his relations with women just as depraved as his uncle Paul's. However, he prioritizes his duties as a knight and does not lay a hand on his comrades, showing more self-control than Paul. He prefers well-endowed beauties and considers those with small chests outside his range. Although he professes to dislike men, he showed he is not heartless toward them by actively engaging in Ariel's struggle for the throne as the "wish of a departed friend" after his colleague Derrick died. His loyalty to his lord, Ariel, is profound; she relies on him heavily, and they share a firm bond distinct from romantic love. As is common for Guardian Knights—who have historically been decorative bodyguards and tools for influential nobles to show off—his talent for the sword is low. Despite receiving education to become a Guardian Knight since childhood, he has only reached Intermediate rank in the North God Style and Beginner rank in the Water God Style, which is not particularly impressive. However, as he is the bodyguard of a major power's princess, he uses very expensive equipment.

Ariel Anemoi Asura Like many of the eccentric royalty and nobility of the Asura Kingdom, she possesses unique sexual preferences and is attracted to the same sex. Having experienced numerous assassination attempts since childhood, she conversely awakened to a sadistic desire to torment others. Specifically, she seems to find intense excitement in situations where she uses her power to make "strong" opponents submit. Additionally, a certain incident revealed her aptitude for masochism, making her capable of being both dominant and submissive.
