Guardian Mage to Princess Ariel Anemoi Asura, the second princess of the Asura Kingdom. Her true identity is Sylphiette, Rudeus's childhood friend. She hides her identity to protect herself from the political strife of the Asura Kingdom, living as a man with short hair and special sunglasses. Like Rudeus, she is a rare user of voiceless incantations, and because she rarely speaks, she is known by the alias "Silent Fitz." She has short white hair and wears black sunglasses. Typical of the Long-Eared race, she has a petite, slender build and long ears. Small stature. First person: I (soft, boyish). Since she is usually quiet and always by Princess Ariel's side, few people know her true personality. Female.

Luke Notos Greyrat. CV: Kazuyuki Okitsu Guardian Knight to Princess Ariel Anemoi Asura. A confidant who has been by Ariel's side since childhood. The second son of the Notos Greyrat family, one of the four regional high-ranking noble houses. His father, Philemon, is Paulo'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 hedonistic life with her, but became active in the succession struggle once Ariel resolved to aim for the throne. He is a handsome man with light brown hair swept back, a high nose, and a sharp chin—a deep-featured face popular in the Central Continent. Rudeus remarked that he resembles Paulo. This face contributes to his popularity with women. A self-proclaimed and widely recognized womanizer and playboy. A dandy said to never bore a woman with his skillful conversation, making every girl he speaks to fall for him. He is excellent at judging women and claims his specialty is finding their good points, though he mostly uses this to "filter out toxic women who would be bad to get involved with." Furthermore, he often makes misogynistic remarks such as "A wife should just listen to what her husband says" and "A man can keep as many women as he can handle, but the reverse isn't true (men are allowed harems, women must love one man)." He has often settled matters with money after having his way, leading some women to loathe him like a snake or scorpion as an enemy of women. 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 reputation with women as bad as his uncle Paulo's. However, he prioritizes his duties as a knight and does not lay a hand on his comrades, showing more self-restraint than Paulo. His preference is for large-breasted beauties; small breasts are outside his strike zone. While he claims to dislike men, he became proactive in Ariel's struggle for power following the death of his colleague Derrick, calling it "the wish of a departed friend," showing he is not without sentiment toward men. His loyalty to his lord Ariel is profound, and she relies on him heavily, forming a bond that is distinct from romantic feelings. As is common for Guardian Knights—who are traditionally decorative guards used as status symbols for powerful nobles—he has little talent for the sword. Despite being educated since childhood to be a guardian knight, his skills are mediocre, reaching only Intermediate in the Sword God Style and Beginner in the Water God Style. "Besides, a honey trap is impossible with Sylphie's body." "In fact, I don't find Sylphie attractive in the slightest."

Second Princess of the Asura Kingdom. The only daughter of the current King's primary consort and the only one with legitimate Asura royal blood. She is third in line for the throne, following her two older brothers. Due to her high charisma, she enjoys strong support from the public, causing her to be viewed as a threat by the first prince, Grabel, who is competing for the throne. At the time of Rudeus's enrollment, she has lost a political struggle and is taking refuge at the Ranoa University of Magic under the guise of studying abroad to escape assassins, where she serves as the Student Council President. Her guardian mage Derrick described her as an "action-oriented woman" and "diligent, social, and willing to spare no effort for self-improvement." However, having grown up in the Asura Royal Palace—a whirlpool of power struggles since childhood—she cynically analyzes the nobles who fawn over her as people who will "betray her when it counts." Consequently, she initially had no interest in the throne, spending her days drinking tea in the White Lily Garden and her nights taking maids to her bed in a hedonistic lifestyle. This behavior was largely due to her having assessed her own limits, believing she could not defeat her older brothers (especially the first prince) who were born earlier and had built connections and achievements before her. However, after receiving the dying wish and resolve of her guardian mage Derrick, who died protecting her from a monster that appeared in the royal castle during the Fittoa Region Teleportation Incident, she resolved to become Queen. As such, she possesses the qualities of a ruler who does not waste the intentions of those who have devoted themselves to her. On the other hand, like many of the eccentric Asura royalty and nobility, she has peculiar sexual tastes and is bisexual. Having experienced numerous assassination attempts since childhood, she conversely awakened to a sadistic desire to torment others. Specifically, she apparently feels intense excitement in situations where she uses her power to make a "strong" opponent submit. A certain incident also revealed her potential for masochism, making her versatile as both a dominant and a submissive.
