Background / History

Li Sijie states that her interest in bondage predates her magical-girl awakening; she retaliated against people who mocked her body by tying them up. She became a magical girl only after graduating high school, despite believing she was beyond the usual age range for selection. She does not understand why she was chosen, and later declines to explain her personal reason for seeking Demonfall. 11 97

She first enters Li Xuan's life as an applicant for a summer maid position at his café. A photography student with an interest in anime and novels, she impresses him by recognizing the intent behind his custom maid-uniform design. She proves competent at café work and accounting while maintaining a poised, intellectual public image. 4 7 12

Li Sijie later reveals herself as a magical girl after secretly binding Xu Rou in Li Xuan's home. Having sensed Li Xuan's Evil Energy since it first appeared in Clear Lotus City, she had investigated him, discovered his ability to turn magical girls into monsters, and approached him with intelligence on the Church's incoming investigators. In exchange, she asks him to eventually help her become a monster. 10

Her first attempt to undergo Demonfall through Fallen Blood fails. She explains that the amount is insufficient to change her, comparing it to a drop of ink in the ocean; a later, much larger dose also fails to complete the transformation. 10 32

Li Sijie makes a longer-term agreement with Li Xuan: once he is powerful enough, he will help her abduct the Church magical girl Fourteenth Night Hongzhen. She offers any reward for his cooperation, including lifelong service as his exclusive toy. 11

Appearance

Li Sijie is a tall woman with long hair reaching her hips and a notably mature, professional bearing. Her ordinary clothing ranges from campus casualwear to maid uniforms, while her transformed appearance resembles a sharply dressed office worker. 7 39 40

• Height: 173 cm. 11
• Build: Her magical-girl data lists a G-cup bust. 11
• Hair: Worn long and loose or braided; she can conceal blades within it. 7 41
• Café uniform: Lace headband, layered apron, large waist bow, and thigh-high stockings. 7
• Transformed attire: White blouse, black pencil skirt, sheer black stockings, and strappy high heels. 40
• Signature accessory: She consistently wears stockings, often changing pairs to maintain access to her magic. 11 94

Personality

Li Sijie is composed, articulate, and deliberately mysterious. She cultivates the image of a capable student, maid, and secretary, but her calm manner conceals an obsessive interest in stockings, bondage, and photographing restrained magical girls. 12 41 100

She is highly independent even around allies. Li Xuan repeatedly finds that she withholds information, appears without warning, or vanishes when she chooses; her departure in the Lost Lands leaves only a magical message on a pair of stockings. 32 102

Despite her unsettling interests, Li Sijie is attentive and practical. She cooks, cleans, handles accounts, tends Li Xuan's injuries after his battle with Shichimiya Mayoi, and helps rescue Lilika from the Church. 11 12 93 97

Her photography studies are one of the few subjects she treats with complete seriousness. She wants to become a photographer capable of preserving her ideal bondage compositions, particularly if she succeeds in capturing Fourteenth Night Hongzhen. 41

Abilities & Skills

Stocking Manipulation and Magic Sealing

Li Sijie's unique ability allows her to control stockings that she has personally worn. 11

• Her stockings can completely isolate magical power, concealing her aura and preventing ordinary detection of her magical-girl identity. 11
• When used to bind a target's torso, the stockings can prevent a magical girl from using magic; Li Sijie claims the effect would work even on the Church president. 11
• She can use stockings as a seal between two magical girls, allowing one person to supply the other's magical power while retaining the ability to cut off that supply. 96
• A stocking can temporarily contain a dissipating soul, as demonstrated when she seals Jiesha's soul after removing her from the Oracle Machine Container. 99
• Her transformed stockings cannot be torn through physical force because they are magical clothing. 41

Barrier and Sealcraft

As a Sealing Type, Li Sijie uses barriers and seals with exceptional flexibility. Her displayed magic consistently falls within these disciplines. 101

• She can remove existing barriers and replace them with her own sealed barrier, isolating an entire Church building from the outside. 97
• She identified and broke the hidden seal protecting the Oracle Machine's chamber. 99
• She understands advanced techniques such as the Dual Prohibition Barrier, which can interfere with both mental and material realms. 34
• She created Cheng Xuan's chains and clothing with sealing magic, allowing Cheng Xuan's nighttime energy form to interact with the material world. 96
• She can establish layered barriers over an area to reveal and access concealed locations, including the Lost Lands. 101

Sensory Perception

Li Sijie's perception is strong enough to make her a valuable reconnaissance specialist. She sensed Li Xuan's Evil Energy from its first appearance in Clear Lotus City and later traced it back to his human identity. 10

• She can sense a person's gaze and infer where they are looking. 41 130
• She can distinguish between Evil Energy from a living creature, concentrated magical energy, mental attacks, and spatial disturbances. 41
• Her perception is effective at range; Li Xuan uses her as a benchmark while testing which of his skills Sealing Types can detect from 200 meters away. 40 41
• She cautions that observation is reciprocal: anyone who observes another person must be prepared to be noticed in return. 33 130

Ropework and Covert Capture

Li Sijie is an accomplished bondage practitioner and teaches Li Xuan a detailed rope-binding method designed to immobilize targets while emphasizing their form. 11

• She can rapidly and securely bind magical girls, including Shichimiya Mayoi, a Grade S magical girl. 94
• Her capture of Mayoi relied on an ambush after Mayoi had expended considerable magic power against Li Xuan. 94
• She carries rope and can prepare it with her own blended essential oils to avoid injuring a captive's skin. 94
• She considers direct combat outside her specialty, favoring concealment, seals, preparation, and ambushes instead. 40 94

Intelligence Network

Li Sijie gathers information independently and maintains Cheng Xuan as an intelligence agent. 96

• She warned Li Xuan in advance about the arrival of Church investigators Tan Xiang and Yun Ye. 10
• She tracked the Church's pursuit of her through the Oracle Machine's marking system. 94
• She uses Cheng Xuan's unusual daytime magical-girl and nighttime energy-body states for covert surveillance. 96
• She later offers to force the Spider King into appearing so Cheng Xuan can locate her. 130

Equipment / Weapons / Items

• Magical stockings — Her primary sealing medium; conceal magical power, restrain magic, and preserve souls temporarily. 11 99
• Rope and essential oils — Used for elaborate bindings and covert captures. 11 94
• Concealed blades — Hidden in her hair and returned to it after use. 41
• Razor blade — Concealed beneath her tongue. 97
• Maid apron — Frequently worn in both café work and domestic settings; she keeps practical items such as rope available in it. 11 93

Relationships

• Li Xuan — Employer, ally, and most important partner. Li Sijie joins his café as a maid, reveals his Church threat, aids his operations, rescues him after his defeat by Mayoi, and later introduces herself to Witch Academy as his secretary. Their relationship is close but remains complicated by her secrecy and independent agenda. 4 10 93 100 102
• Cheng Xuan — Her intelligence agent and beneficiary. Li Sijie saved Cheng Xuan during Light Dissolution, restored her magical-girl form with sealing magic, and equipped her with chains that let her affect the physical world at night. 96
• Fourteenth Night Hongzhen — Li Sijie's intended abduction target. She asks Li Xuan to help capture her once he is sufficiently strong. 11
• The Church — Her enemy. The Oracle Machine marked her location and the Church dispatched dozens of magical girls to eliminate her, forcing her to flee Clear Lotus City. 10 94
• Lilika and Witch Academy — Li Sijie assists in the rescue of Lilika and the captured magical girls, then formally presents herself to the group as Li Xuan's secretary. 97 100
• Shichimiya Mayoi — A captured Grade S magical girl. Li Sijie ambushes, binds, and delivers Mayoi to Li Xuan after his battle with her. 94 95

Later evidence links her to Perol's alliance with the Snake Demons and the plot against Wang Li, though she insists she is only making use of the monsters rather than joining them. 102 112 116 130 131
