Background / History

Margaret is a Capet-family noble and Saint Dero lecturer who became the academy's youngest lecturer at age twenty-one. By age eighteen, she held five spell patents, which initially makes Jia Xiu's thirty Basic Healing Spell patents seem implausible to her. After personally reviewing all thirty submissions and inspecting his improvised utility-room laboratory, she concludes that his work is genuine and exceptional. 1

As an evaluator for Creekwood Town's Excellent Young Spellcaster Award, Margaret prioritizes academic integrity and personal character. She rejects candidates associated with harassment, fraud, or purchased research, and chooses to back Jia Xiu despite the political controversy of recognizing a Warlock during rising tensions with the Devil Race. 1

She intervenes when Hannas, the baron's son, receives performance-enhancing potions before their award duel. Unable to openly invoke her family influence, she covertly leaves Jia Xiu a rare-grade ring containing Dominate Human by pretending to have “found” it. 2

After accepting Jia Xiu's address of “Mentor,” Margaret grants him access to a laboratory, provides an experimental guidebook and remote-contact method, and prepares him for Saint Dero's entrance examination. 4 During the examination, she becomes increasingly protective of him, worries over his eccentric conduct, and attempts to prevent Reinhardt-affiliated examiner Gudrian from overwhelming Jia Xiu's group with fourth-circle spells. 43 45

Jia Xiu's rapid progress gradually overturns their original mentor-student dynamic. After he surpasses her research ability within half a year, Margaret abandons her attempt to solve his vampire-rune replacement research independently, returns to Conjuration, and takes responsibility for coordinating data and external communication as the laboratory's corresponding author. 133

Margaret later contributes to Blood Clan Magic classification, Devil Race investigations, detection-spell research, magical-circuit experiments, and golem construction. 199 224 342 353 When Jia Xiu withdraws to investigate a void storm, she assumes leadership of the Magic-Energy Computer team. 397

By the epilogue, she remains a Saint Dero instructor and is considered for promotion from associate professor to full professor, potentially becoming the academy's youngest full professor. The proposed promotion rests largely on the extraordinary achievements of her students and laboratory. 469

Appearance

Margaret is a tall young woman who can transform into a jet-black cat with amber eyes. 1

• Frequently carries extensive luggage, cosmetics, and more than twenty outfits when traveling. 108
• Uses a golden-haired disguise during the Unity Society investigation; Jia Xiu suspects the look was partly modeled on Princess Emilia. 215
• Is commonly described with disheveled hair and darkened eyes after extended research sessions. 133
• Wears numerous enchanted accessories in combat, including earrings, a necklace, rings, belt, bracelets, and other magical items. 235

Personality

Margaret is principled about fairness and academic ethics, particularly hostile toward plagiarism, fraudulent research, and abuse of privilege. Her support for Jia Xiu begins with a careful verification of his work rather than blind admiration. 1

She is proud, competitive, and highly conscious of her identity as a mentor. She reacts strongly when other professors, military representatives, or foreign agents attempt to recruit Jia Xiu, often hiding her irritation behind an aristocratic “fake smile.” 72 73 278 Her protectiveness can become excessive: she sees Jia Xiu's exam teammates as liabilities and fears that his early graduation will make her seem like a merely nominal mentor. 45 252

Although raised as an aristocrat, Margaret dislikes rigid noble etiquette and was sent away to study partly because she was unsuited to social maneuvering and exchanging favors. 284 The Capet family's martial tradition remains important to her; she accepts that she cannot aid her relatives at the border directly and focuses on her own work instead. 289

She initially struggles with Jia Xiu's increasingly advanced research, but eventually makes peace with her limits and finds satisfaction in demanding, achievable work such as data processing, spell classification, and laboratory coordination. 133 199 She later reassesses her teaching and adopts a more systematic, student-centered approach rather than simply overwhelming students with knowledge. 395

Abilities & Skills

Spellcasting

Margaret is a highly proficient offensive spellcaster with fast casting and strong combat discipline. She prepares layered defenses and enhancements before engaging an opponent rather than relying on raw confidence alone. 235

• Can transform into a black cat. 1
• Uses Grappling Vine to restrain Jia Xiu when she believes his research-induced behavior is dangerous. 156
• Employs Water Creation Spell followed by chain lightning to destroy a necromancer's animated corpses. 235
• Casts Silence as part of a containment defense to prevent a Flame Demon from using incantations. 241
• Demonstrates particularly strong proficiency and casting speed even when her spell level is set aside. 241
• Can teleport, though Jia Xiu finds Dean Nico's teleportation more comfortable. 252

Conjuration and Golem Crafting

After setting aside vampire-rune research, Margaret returns to Conjuration as her preferred field. 133

• Advises Jia Xiu on using Tatiana's tissue as a potential golem material for Magic-Energy Computer research. 352
• Constructs twenty small golems from the available tissue, each using a different essence for comparative testing. 353
• Prefers large golems, believing that massive constructs with impressive armor are inherently cooler. 353
• Is more confident in practical function than fine appearance-shaping, though she disputes that this is a weakness. 353

Mental and Investigative Magic

Margaret contributes magical investigation and intelligence work during the Unity Society case.

• Probes a captured necromancer's mind after his resistance collapses, uncovering his history and connection to Paula. 236
• Uses a professionally designed surveillance spell able to collect and filter sound within roughly fifty meters, including through several walls. 238
• Uses an Eye of Detection during the group's reporter disguise, though she lacks skill with its image-recording and reproduction functions. 222
• Identifies Becky as a noble-circles wanted criminal with help from her mother. 224

Equipment

• Legendary wand — Gemstone-set, precious-wood wand with a master's enchantment; used during the confrontation with the Unity Society necromancer. 235
• Enchanted accessories — Numerous rings, earrings, bracelets, a necklace, belt, and other items that provide stacked combat enhancements and shields. 235
• Spatial storage item — Used for supplies, clothing, cards, and laboratory materials, though it is often full. 108 242
• Experimental Guidebook — A comprehensive laboratory reference she gives Jia Xiu after opening her laboratory to him. 4

Relationships

• Jia Xiu — Her student and later close research collaborator. Margaret recruits him after verifying his patents, protects him from unfair treatment and poaching, and eventually supports his projects as coordinator, assistant, and laboratory leader when necessary. 1 72 133 397
• Mia — One of Margaret's students and a member of her laboratory. Margaret is visibly proud of Mia's potential Nature publication and works with her on later research. 75 252
• Ram — One of Margaret's students and a laboratory member; Margaret later helps oversee the Magic-Energy Computer team that includes his work on the Quaternary Insect. 252 421
• Gillianis — Close friend and drinking companion. Margaret addresses her as “Sister,” despite being uncomfortable with Gillianis's overly refined public persona. 142 156
• Princess Emilia — Margaret's close friend. Emilia teases her over Jia Xiu, while Margaret is suspicious of Emilia's interest in him. 12 27
• Justina — An informal acquaintance of the Radiant Knight; their familiarity surprises Margaret's family and fortress personnel. 284
• Aurelius — A legendary professor whose return distresses Margaret because he humiliated her in the past, despite his teaching having contributed to her development. 84
• The Reinhardt family — Margaret's Capet family has a longstanding rivalry with the Reinhardts, making her especially suspicious of Gudrian's handling of Jia Xiu's examination. 36 45

Trivia

• Margaret once tested whether cat transformation could avoid allergic rhinitis, only to discover that cats can suffer allergies as well. 162
• She is enthusiastic about shopping and has been known to buy nearly an entire store display while leaving Mia to handle payment and Ram to carry the purchases. 156
• Despite her noble upbringing, she plays Noble Duel without concern for the game's implications, declaring that she can simply seize the noble role every round. 242
• Her personal pride in Jia Xiu's brilliance is mixed with jealousy; she calls him a “freak” as a compliment. 325
