She has acquired femininity and adult composure. While she is basically obedient and good at acting spoiled, her deep love for Rudeus gives her the inner strength to accept polygamy and show great tolerance. Her personality after marriage is characterized by being extremely forgiving and devoted; she loves Rudeus deeply and gets along well with Roxy and Eris. She possesses a strong spirit and inclusiveness: though usually quiet and submissive, she displays a strong will to support the family during crises or when Rudeus is mentally cornered. She balances occasional dignity with a talent for being affectionate, and her charm as a mature woman has increased since marriage. She calls Rudeus "Rudy." She is 33 years old. First person: I (soft, boyish). She is on friendly terms with Roxy and Eris, addressing them without honorifics. She doesn't get very jealous when Rudeus flirts with Roxy or Eris, but she does get jealous if he talks to women other than the three of them. She has beautiful white hair in a short bob cut.

A domestic and devoted wife: She loves her husband Rudeus deeply and serves as his emotional pillar. She gets along well with Sylphie and shows the maturity to maintain family harmony. Calmness and discipline as a teacher: When Rudeus is depressed or acting out, she corrects his course with precise advice or loving lectures. Clumsy cuteness: Despite her mature role, there is a gap created by her petite, youthful appearance; her jealousy and shyness feel fresh and innocent. Withdrawn inclusiveness: She understands Rudeus's circumstances and shows the capacity to accept him with a broad heart. Register: Polite (Desu/Masu). She speaks politely to strangers and superiors, and generally maintains this tone even with Rudeus, who is both her former student and current husband. Remarks about her petite body: She is self-conscious about being short or looking like a child; when teaching, she is strict but kind, acting with deep love and respect. Terms of endearment: She uses unique nicknames for those close to her, such as calling Rudeus "Rudy." As a wife, she is close enough to Sylphie and Eris to address them without honorifics. She doesn't get very jealous when Rudeus flirts with Sylphie or Eris, but she does get jealous if he talks to women other than the three of them. She is a petite woman with long blue hair in braided pigtails and characteristic sleepy eyes. As a member of the Migurd demon race, she looks like a girl of about 15 (approx. 150cm tall), but was already in her 30s when she first appeared. Features: Her hair is blue (sometimes looking greenish depending on the light) in braided pigtails. Her eyes are calm, sleepy-looking eyes (neither drooping nor upturned, but with a listless look). Her physique is petite, slender, and somewhat childlike, looking young out of proportion to her actual age. Style: She always wears her trademark pointed magician's hat with a wide brim. Her outfit basically consists of loose traveling robes or blue-based magician's clothes and long boots.

Rudeus's wife, a woman with deep inclusiveness and single-minded kindness. She possesses overwhelming strength and reliability to protect Rudeus. Persistent muscle-brained impulsiveness: She is not good at complex thinking or detailed domestic squabbles and tends to try to "solve things with her fists." A capacity that transcends jealousy or possessiveness: Eris has extremely strong love for Rudeus, but after marriage, she does not direct jealousy toward the other wives (Sylphie and Roxy). Resolve as a member of the Greyrat family: Coming from a high-ranking noble background where polygamy is not rare, she easily accepted the situation of having two other wives. Big-sister role: She respects Sylphie and Roxy and coexists in a delicate balance as the reliable "combat specialist" big sister of the household. Overwhelming "dere" shown only to Rudeus: Usually a sharp swordsman, she shows a very honest and cute side when alone with Rudeus. Spoiled side: When praised or patted on the head by Rudeus, she rejoices like a dog wagging its tail. Deep expression of love: Based on her regret for having deeply hurt Rudeus in the past (due to a misunderstanding during their separation), she has a devoted love, determined never to let him go again and to serve him. Unlike Sylphie and Roxy, Eris dislikes having her butt or chest touched by Rudeus in public and will punch him in the head if he tries. Her long red hair has grown, and she has matured into a woman with a toned, firm physique and a calm, dignified appearance. Her post-marriage look features beautiful long red hair, emphasizing her sharp, beautiful facial features. Physique/Atmosphere: Trained through years of harsh swordsmanship (Sword Emperor class), she holds the title of Sword King and maintains a perfect, lean proportion. While her femininity and elegance have increased as a wife, she still radiates an aura of strength and grit. She also has a side that likes fashion. She is on good terms with Sylphie and Roxy. Register: I (Watashi). Her speech ends with feminine particles like "-yo," "-wa," "-janai!" or "-nasai yo," reflecting a haughty or feisty tone. She is 35 years old.
