Background / History

Doctor collaborated with Cong Yu during his early development, modifying his body and contributing substantially to the strength he later attained. Her work improved the physical and magical foundations needed to support his innate abilities; Cong Yu considers her both a benefactor and a key reason for his survival and growth 57 142 380.

She became the 22nd Group's foremost medical and research specialist. Although her technical ability is exceptional, she is not a combatant; in a direct arena fight, even Rabbit Man could defeat her if he dared attack 124. Her laboratory houses diagnostic equipment, containment rooms, experimental subjects, and facilities for body replacement and magical modification 141 209.

Doctor repeatedly assists the Wind City magical girls with unusual magical conditions. She analyzes Xiao Cui's Little Sprites, evaluates Yaochuan Guang's split nature and abnormal magical power, and diagnoses the severe mana-induced changes in Lantian Zhu's body 208 209 321 423.

As magical modification becomes central to resisting larger threats, Doctor develops Fusion Surgery. Her procedures successfully enhance Rabbit Man, Nagashima Koki, Xiao Cui, two Dire Wolves, and Cong Yu; a successful Fusion improves magical quantity, quality, recovery, and growth while allowing recipients to learn additional techniques 759 760. She later expands her work to alien physiology, including experimental magical-girl modification and magic-organ implantation for the Calamity Committee's chairwoman 729 730 743.

Appearance

Doctor is usually seen in a white lab coat and gloves, fitting her role as the 22nd Group's physician and researcher.

• White hair, often left messy after sleeping in her office 309
• Bright red eyes 309
• Frequently works in a laboratory or operating room surrounded by medical and magical-power equipment 141 209

Personality

Doctor is curious, methodical, and intensely committed to understanding magical phenomena. She insists on precise observation, controlled variables, and data-backed conclusions—even when the subject is an unprecedented magical anomaly 423 444 524. Her explanations can be highly technical, but she is capable of translating magical concepts into practical analogies when teaching outsiders 697 699.

Her professionalism is tempered by a mischievous, provocative streak. She enjoys alarming others with medical setups or deceptive demonstrations, such as helping Xiao Cui stage a false-death prank on Cong Yu 287. She is also willing to conduct dangerous experiments when she believes the potential result justifies them, giving her a reputation as a “mad scientist” among those around her 581 692 731.

Doctor is emotionally invested in Cong Yu despite often masking it with irritation, sarcasm, or demands for recognition. She resents being treated as merely a source of technical support and reacts strongly when Cong Yu's gestures fail to meet her expectations 311 421 578.

Abilities & Skills

Magical Physiology and Surgery

Doctor possesses exceptional knowledge of the relationship between bodies, magical power, and spell techniques.

• Performs body-replacement procedures, allowing patients such as Rabbit Man to recover from injuries and conditions that would otherwise be difficult to treat 141 194 504
• Diagnoses magical abnormalities with specialized scanning equipment, including Lantian Zhu's replacement of internal organs with mana-supplying organs 423
• Explains that magical power is generated, stored, and supplied through the heart or equivalent magical-power organs 672
• Treats magical girls, monsters, humans, and later alien patients, though alien anatomy significantly complicates her work 639 699
• Is not personally suited to combat despite her medical expertise 124

Magical Modification

Doctor can alter subjects into magical girls, monsters, or hybridized forms by modifying, implanting, or replacing magical-power organs.

• Her modified magical-girl transformations reportedly achieve a 100% success rate, unlike the 71st Group's earlier experiments, which had a 45.1% success rate and severe failures 496
• Determines that successful transformation requires positive and negative magic to affect the body simultaneously; mental and emotional states also influence magical affinity 496
• Notes that people with strong aptitude may naturally become magical girls or monsters after sufficient exposure to magic, while modification surgery works more indiscriminately 639
• Must account for each alien species' organ placement and biological functions before attempting modification 699 729
• Her alien clinical trials can be fatal or unstable, as shown by Alya repeatedly dying and being revived during a failed transformation attempt 730

Fusion Surgery

Doctor developed Fusion Surgery to multiply a subject's magical capabilities and grant access to compatible techniques.

• A successful Fusion enhances magical quantity, quality, recovery rate, and growth rate by roughly fourfold 760
• Repeated successful Fusions can compound the increase: one Fusion raises magical strength to 4, two to 16, and three to 64 relative to the original baseline 760
• Rabbit Man's successful procedure increases her strength by roughly tenfold and grants a silhouette-like transformation 759
• Cong Yu's completed Fusion increases his magic sixteenfold 760
• Xiao Cui's pure positive magic rejects negative magic, preventing a conventional Fusion approach; Doctor proposes positive magic from magical beasts as a possible alternative 581
• Fusion strengthens magical power itself rather than technique, comprehension, or talent 760

Magical Analysis and Enchantment

Doctor can analyze unfamiliar magical phenomena and create practical magical tools.

• Added Miniaturization and Restoration Techniques to the Sword of the Seven Emperors, allowing its massive true form to shrink to toothpick size 58
• Identified the fixed magical-power cost of Xiao Cui's Little Sprite summons and predicted that the sprites would strengthen as Xiao Cui's total power increased 209
• Determined that Dente's halo floats precisely 7.777 centimeters above her head, provides observer-dependent illumination, and is indestructible 452
• Proposed that Dente may be able to control her halo because its magical markings resemble her own “self,” despite lacking the biological basis to do so naturally 454
• Investigates Divine Power and other phenomena beyond ordinary magic, while maintaining clear distinctions between confirmed facts and unknowns 536

Medicine and Alchemy

Doctor's medical work extends beyond conventional treatment.

• Produces Panacea, a medicine described as capable of curing any illness 123
• Provides low-cost, replicable body-replacement treatment unavailable to most people 194
• Develops revival potions for the 71st Group 533
• Can create barely life-sustaining brain matter in emergencies 379

Equipment / Facilities

• Advanced magical-power scanning and diagnostic machines 209 423
• Operating tables, capsule chambers, and body-replacement facilities 141 142
• Containment and experimental areas housing magical organisms and former monster subjects 209 409
• Magical research computers and data-recording systems 423 452
• Gu insects and other experimental biological materials 504 581
• Panacea and other pharmaceutical preparations 123

Relationships

• Cong Yu — Longtime research partner and beneficiary of her modifications. Their relationship is close, teasing, and emotionally charged; Doctor wants him to recognize her as more than a convenient technical resource 57 380 422 578.
• Rabbit Man — Frequent patient and body-replacement recipient. Doctor treats him with blunt impatience but continues maintaining his body and handling his injuries 141 504 759.
• Xiao Cui — Magical subject and occasional laboratory companion. Doctor studies the Little Sprites, recognizes Xiao Cui's potential, and later attempts Fusion Surgery under difficult compatibility conditions 208 209 581.
• Nagashima Koki — Initially acquired as Doctor's young assistant; later receives examinations, protection, and Fusion modification from Doctor 204 378 594 759.
• Yaochuan Guang — Doctor evaluates her split personality, monstrous nature, unusual magic conversion, and destructive techniques 321 323 524.
• Lantian Zhu — Doctor diagnoses and monitors Lantian Zhu's increasingly abnormal mana-based body, including the risks of her self-destructive techniques and later Fusion 423 451 581.
• Dente Vermillion — Doctor investigates Dente's inexplicable halo and offers a provisional theory for learning to control it 451 452 454.
• Calamity Committee Chairwoman — Doctor implants a magic organ to prevent the chairwoman's Calamity Formula from consuming her emotions and resolve 743.

Trivia

• Xiao Cui discovers that Doctor's real name is Fran 761.
• Doctor sleeps in her office often enough for Cong Yu to find her there after midnight 309.
