Background / History

Meng Yue was Starry Sky City’s strongest Magical Girl. She spent three years fighting the Monster Organization and became the reliable first responder whenever monsters appeared. Her performance made her more effective than all other Magical Girls in the region combined, while her earnings were turned over to Papi for the stated purpose of funding the war. 1 4 10

During her assault on the Monster Organization’s leader, Bai Yu trapped her in a prepared binding array and attempted to turn her into a mindless Slave Soldier. Meng Yue covertly retained her awareness, recognized herself after seeing a photograph of the Magical Girls, and chose to maintain the act in order to infiltrate the organization and locate the Dark-Energy Converter. 1 2 5

Her deception gradually became genuine corruption. Bai Yu’s treatment, the comforts of the organization, and her growing Beast Core altered her priorities; she became attached to him, increasingly embraced catlike behavior, and lost interest in her former mission except when unhappy or hungry. 6 13 17 19

Memories of being bullied and abused resurfaced, prompting her to lead monster troops against her former tormentors Tang Si and Xu Ranran. The revenge accelerated both her physical mutation and mental decline. 20 22 23

After becoming a Magical Beast, Meng Yue resumed her Magical Girl identity as a double agent. By reversing or concealing her corrupted state, she convinced Papi and Crimson Blade that she had escaped captivity, while secretly gathering intelligence and steering events in Bai Yu’s favor. 50 54 56 61 Her cover was eventually exposed, after which she returned to the Monster Organization. 104

Appearance

Meng Yue’s original Magical Girl form presents a harmless, elegant image, sharply contrasting with her reputation as the region’s strongest defender. Her later Fallen Cat form combines her silver-haired appearance with organic feline features and a black Monster Organization combat uniform. 1 23

• Silver hair, a well-proportioned figure, and a height of approximately 1.6 meters. 1
• Original Magical Girl outfit: a white-and-gold sleeveless dress, white stockings, silver boots, and a magic wand. 1
• Fallen Cat traits include purple vertical pupils, cat ears, a tail, cat paws, claws, and other genuine cat-monster organs. 13 23
• Wears a black, magic-responsive leather bodysuit with a cat-head emblem and a half-face cat mask while operating as a monster. 8
• Can reshape the bodysuit into combat forms, including cat ears, tail, claws, gloves, boots, and other outfit configurations. 12

Personality

Before her fall, Meng Yue was dutiful, sincere, and exceptionally committed to protecting humanity. She worked despite poverty and exhaustion, consistently arrived first at monster incidents, and trusted Papi’s mission without questioning how her earnings were used. 4 10

Even early in captivity, she was clever and mischievous: she feigned intellectual regression to frustrate Bai Yu and investigate his headquarters. Her desire for food, comfort, privileges, and revenge gradually eroded that original discipline. 2 5 9 11

As Fallen Cat, Meng Yue becomes lazy, playful, competitive, and openly manipulative. She enjoys deceiving others, seeks praise from Bai Yu, resents Xinghua’s former laziness, and can become cruel toward people connected to her past suffering. 17 23 34 108 Despite this change, she remains perceptive and highly capable at maintaining her former Magical Girl persona when an operation requires it. 28 54

Abilities & Skills

Purification Magic

Meng Yue’s original magic trait is Purification, a highly destructive anti-monster power.

• Can erase large groups of monsters and Magical Beasts before they can teleport away. 10
• Her strongest documented defensive technique, Pure White Guardian, creates a pillar of Purification light that clears all monsters within a ten-meter radius. 19
• Her Purification is ineffective against ordinary humans. 10
• While her Beast Core is fully converted, she has no Purification magic unless she reverses her core’s state. 50
• Purification magic remains within Crimson Blade’s sword after Meng Yue imbues it into the weapon. 61

Feline Beast Power and Poison

As her core changed into a Beast Core, Meng Yue inherited the traits and instincts of the Purple Phantom Poison Cat. 16 26

• Fights most effectively on all fours, using rapid pounces, claws, tail strikes, and instinctive feline movement. 13
• Can incapacitate targets with poison, as demonstrated against Xinghua. 16
• Uses Purple Poison Thorns, a high-speed venomous projectile attack. 31
• Can alter individual body parts between human and cat-monster forms with unusual precision. 23
• Her agility is described as maxed out, allowing her to evade repeated airborne attacks. 105

Beastification

Meng Yue can fully transform into a Magical Beast after completing the corruption of her Magic Core. 38

• Greatly enhances her physical power beyond her original Magical Girl state. 38 50
• Her Beast Core’s instincts can overwhelm her restraint when she is injured or enraged. 77
• Bai Yu can use Contract Lock to force her out of Beastification. 47

Resurrection

Meng Yue can survive destruction of her Magic Core through the Purple Phantom Poison Cat’s resurrection ability. 26

• Initially requires three days to recover one resurrection. 26
• This ability allowed her to recover after Xinghua pierced her Magic Core and then ambush Xinghua. 26

Teleportation, Illusions, and Deception

• Can teleport herself and allies during combat or retreats. 17 66
• Used illusions to turn Ling Bazi’s subordinates against one another. 50
• Is skilled at impersonating her former Magical Girl self, successfully fooling Xinghua and later Papi. 28 54

Equipment / Weapons / Items

• Magic wand — Meng Yue’s Magical Girl transformation device and focus for Purification magic. 1 98
• Monster Soldier Leather Suit — A black bodysuit fueled by the wearer’s magic power; enhances physical strength and can be reshaped at will. 8 12
• Cat-face mask — A half-mask used to conceal her identity during Monster Organization operations. 8

Relationships

• Bai Yu — Her captor, master, Monster Organization leader, and eventual closest attachment. He manipulated her initial amnesia act, supervised her corruption, and promotes her within the organization; Meng Yue later protects his interests and seeks his approval. 1 16 32 90
• Xinghua — Former Magical Girl teammate and later Monster Organization colleague. Meng Yue resents Xinghua for hiding her strength and slacking off, defeats her for promotion points, and repeatedly taunts her after her capture. 10 17 34 42
• Crimson Blade / Xiao Nai — Former close junior and fellow idealistic Magical Girl. Meng Yue later deceives her while undercover, but also frees her from Ling Li’s ice and continues using Crimson Blade’s trust to influence her choices. 10 58 61 89
• Papi — Her former Contract Spirit. Papi considered Meng Yue its most dependable Magical Girl, making it especially vulnerable to her return as a disguised double agent. 10 54 56
• Judgment — A fellow Magical Girl-turned-captive who becomes jealous of Meng Yue’s status and attacks her. 66
• Tang Si and Xu Ranran — Former bullies and abusers targeted by Meng Yue after memories of her past resurfaced. 22 23

Story Role / Major Arcs

Strongest Magical Girl and Captivity

Meng Yue enters the story as the Magical Girls’ greatest asset and the person expected to defeat Bai Yu. Her apparent defeat removes Starry Sky City’s most effective defender and forces Xinghua and Crimson Blade to take over her duties. 1 6

Fallen Cat’s Rise

While pretending to infiltrate the Monster Organization, Meng Yue is gradually remade into Fallen Cat. Her progression from Slave Soldier to executive is driven by combat points, Beast Core corruption, and her desire for Bai Yu’s approval. 11 17 23 32

Double Agent

After Beastification, Meng Yue resumes her public identity as Magical Girl Meng Yue. Papi and Crimson Blade believe she has returned as an ally, while she secretly reports intelligence to Bai Yu, manipulates Crimson Blade’s ambitions, and helps advance Monster Organization plans. 54 61 89 90

Return to the Monster Organization

Once her cover is exposed, Meng Yue abandons the undercover role and returns to Bai Yu. She requests a luxurious human-world residence and wealth, reflecting how far her values have shifted from the impoverished protector she once was. 104 108
