Background

Fu You was once the Magical Girl Canary. After falling into corruption ten years earlier, he lost that codename and eventually became the original Abyss Witch; the public later believed that Witch had been destroyed. He abandoned the Witch identity two years before the present story and began operating publicly under his real name. 4 19

He works as a professional Magical Girl while posing as a high-school boy. The Special Incident Response Department monitors him with a Magic Power Limiter because of the dangerous dark and witch energy within him, which is nearing its limit. 1 25

Fu You remains tied to both sides of the conflict. He has former subordinates within the Witches’ Society, including Black Card, but works for the Department and repeatedly protects civilians and Magical Girls. His exceptional collateral damage has also left him with an effectively impossible debt; the Department takes most of his earnings toward repayment. 39 62

Appearance

Fu You maintains a delinquent-like male student persona, but his untransformed body has become visibly feminine enough that he relies on clothing, makeup, posture, and distance from others to conceal it. 18 22 23

• Ordinary appearance: Black-haired, slender student with long hair and a conspicuous red earring; classmates often mistake his aloofness for delinquency. 1 18
• Magical Girl form: Petite black-and-gold Magical Girl with blond hair, twin tails, a prominent bow, and a long staff. 1 5 6
• Distinctive traits: Red eyes when angered or using darkness; fair skin, delicate hands, and a physique that makes his claimed gender difficult for others to accept. 4 21
• Presentation: His magical outfit is predominantly black with gold details; its darkness causes other Magical Girls to associate him with corruption. 14 34

Personality

Fu You is cynical, solitary, and openly contemptuous of idealized Magical Girl heroism. He treats missions as paid work, complains about quotas and unpaid overtime, and deliberately acts cold enough to discourage people from approaching him. 2 27 55

His hostility conceals a practical moral code. He saves hostages, protects inexperienced Magical Girls during battles, rescues even rivals such as Huang Xing and Huang Ying, and takes Huali’s training seriously despite insisting that it is only professional responsibility. 1 66 98

He is highly protective of his privacy, especially his gender and former identities. Physical scrutiny, questions about his body, and references to Canary or the Abyss Witch make him immediately defensive. 4 20 22

Fu You also has a theatrical and vain streak. He enjoys Huali’s admiration, privately admires his own televised image, and is easily embarrassed when caught showing affection for desserts or other traditionally feminine interests. 17 37

Abilities & Skills

Magical Girl Transformation

Fu You transforms through his red earring, shifting from his ordinary identity into a powerful Magical Girl form. His transformed body possesses extreme mobility, strength, and resilience beyond that of his ordinary body. 4 5

• His magical form can traverse walls and move through the air with movements that defy ordinary physics. 5
• He possesses an unusually large magic reserve and can maintain transformation more freely than most Magical Girls. 8
• His ordinary body remains physically vulnerable despite his combat strength while transformed. 22
• The Magic Power Limiter can detect and report his dark magic, but he states that it cannot truly restrain him. 25

Dark Magic and Witch Affinity

Fu You wields unusually pure dark magic due to his former corruption and Witch identity. This power causes other Magical Girls to fear him and makes him vulnerable to eventually becoming a Witch again. 1 25 99

• His dark aura can trigger the Limiter’s alarm and alarm nearby Magical Girls. 25
• He can recognize a Witch’s presence by comparing the intensity of dark-magic fluctuations detected by his wristband. 26
• He restored Huang Ying’s depleted Magic Core with his own magic power, though Huang Xing feared the transfer could contaminate her. 86 88
• His darkness gives him unusually sharp vision and comfort in unlit environments. 10

Staff Combat

Although his weapon resembles a mage’s staff, Fu You is a devastating close-quarters fighter. He uses the staff as a crushing melee weapon, combining reach, speed, and precise control. 5 9

• His staff strikes can create craters and overwhelm opponents who assume he is a conventional ranged caster. 9
• He trains Huali through controlled but punishing staff combat, emphasizing evasion, timing, counters, and survival. 9 47 100
• He can physically block the White Witch’s otherwise intangible tentacles with the staff. 66

Black-and-White Ultimate Attack

Fu You can charge a massive black-and-white beam through his staff. During the charge, he progresses through four stages before releasing a destructive pillar of light. 5

• He warned the Abyss Witch that the attack has a range of roughly one thousand meters. 4
• The attack dispersed darkness and was decisive against the Witch’s final form at the school. 5 34
• Its scale makes it dangerous to use near civilians or structures. 1 4

Witch Knowledge and Strategy

Fu You’s experience as both a Witch and a Magical Girl gives him knowledge the Department lacks. He identifies Witch stages, evaluates domains, and monitors conflicts within regional Witches’ Societies. 26 39

• He arranged staged public battles with the current Abyss Witch to preserve her survival while maintaining their hero-and-villain appearances. 4
• He recognized that the Black Stockings Witch had reached the fourth stage and could create a domain. 39
• He uses Black Card to investigate Witch activity and rival Witches’ Society factions. 39

Relationships

• Jiang Ke’an / Dark Witch — Fu You’s former final opponent and the person responsible for his corruption. He avoids her, fears her possessiveness, and resents her for exposing his secrets. 6 18 52 99
• Current Abyss Witch — Fu You’s successor and admirer. He covertly guides her survival while requiring their public encounters to resemble genuine battles. 3 4
• Black Card — Former subordinate who remains loyal because Fu You once spared her life. She provides intelligence on Witch activity. 1 39
• Huang Xing — Rival Magical Girl who considers Fu You corrupted and untrustworthy. Their hostility persists even when Fu You saves her life. 14 34 66
• Huang Ying — Younger Magical Girl whom Fu You rescues and restores with magic power; she develops strong admiration for him afterward. 66 86
• Yuan Xiaofang / Grey Magpie — Retired elite Magical Girl who helped guide Fu You early in his career. She calls him “Little Sparrow” and treats him with warm, teasing familiarity. 37 38
• Red Sleeve — A district protector Fu You respects for her competence, restraint, and understanding of personal boundaries. 66 73
