Two of Hearts—first containment	2–3	Contains a near-death Deformed Person, then learns he can release, command, and fuse with it. Fusion multiplies his physical ability and lets the creature retain use of its original weapons.
First ability extraction	4	Contains Mutated Ogres and draws Vision Enhancement, granting limited night-vision-like sight.
Fourth sequence unlocked	12	Contains injured Wendigos in Bolehan Cave, reaching eight controlled subordinates and unlocking the fourth sequence.
Diamond Four—Evil Spirit Wendigo	16	Contains the near-death Evil Spirit Wendigo after the cave explosion. Fusion grants overwhelming strength and access to its bone-spike second form.
Club Five—Soul Severing Clown	27	Contains Art after researching the limits of his fragmented immortality. The containment releases the entire Series Six.
Four of Clubs—Bat Person	38	Restrains the bulletproof, flying Bat Person with the Evil Spirit Wendigo, then seals it using two cards.
Incomplete Immortal Body	39–40	Extracts the Bat Person's Immortal Body (Incomplete). It grants high-temperature resistance and rapid regeneration at the cost of stamina.
Ace functions unlocked	50	Diamond Ace provides personal storage space; Club Ace permits unlimited containment-type cards.
Gothic Grand Theater rewind	57	The Ghost Card identifies the theater as Dead Silence · Gothic Grand Theater and unlocks a rewind function that lets Li Dan investigate its past.
Flash Step	76	Obtains Jason's short-range, teleportation-like movement ability. It consumes substantial energy and cannot pass through physical obstacles.
Hell Form Evil Spirit Wendigo	130	The Evil Spirit Wendigo evolves into its third form, gaining Ghostfire and enough power to contend with exceptionally powerful supernatural entities.
Ghost Card Reshuffle—Fusion system	130	Uses the damaged Wish Music Box to replace the unreliable Ability Extraction function with a more dependable Fusion function, capable of permanently absorbing compatible powers or combining compatible contained entities.
Completed Immortal Body and Paranormal Transformation	139	Permanent fusion completes Li Dan's Immortal Body, vastly enhances his physique, and allows him to spiritualize into a demon-level paranormal form with flight and ghost-like intangibility.
Kayako–Toshio Guard Card	178	Seals Kayako after suppressing her with Ghost Lake, Mary Shaw's mist, and the Nursery Rhyme Curse. Kayako's card absorbs Toshio's and becomes a Guard Card.
Deadlights containment	213	Tricks the Deadlights into entering his consciousness, withstands their fear-based mental assault, and seals the weakened extradimensional entity for possible future Fusion.
Ghost Mirror and Mirror Domain	286–289	Subdues the Ghost Mirror using Ghost Lake and gains access to the Mirror Domain, eventually allowing Ailan to obtain an independent physical existence.

Background

Li Dan was a Chinese international student at Round Clam Public School when lightning struck him while he watched horror commentary videos. The incident placed a deck of Ghost Cards in his mind, which could detect supernatural traces and eventually contain anomalous beings. His first warning came when the cards detected traces of the Ghost Nun after he encountered a Vatican priest. 1

Realizing that North America was filled with monsters, evil spirits, demons, and murderers, Li Dan decided that survival required using horror against horror. He began seeking containable entities rather than relying on conventional protection. 1

During a trip to North Carolina, he encountered the cannibals from Wrong Turn. He returned alone to their cabin to contain an injured Deformed Person, beginning his use of supernatural subordinates and ability extraction. 2 4

Li Dan initially treated supernatural incidents as survival threats and sources of potential Ghost Card materials. As his power grew, he began deliberately cultivating contacts with paranormal investigators, the Church, Taoist practitioners, government containment organizations, mediums, and supernatural beings across North America and Asia. 32 79 178 312

By the time of his Hong Kong investigations, Li Dan had become powerful enough that orthodox exorcists regarded his command of ghosts, corpses, demons, and monsters as something close to the forbidden Ghost Path. He nevertheless insists that he uses this power according to his own judgment rather than conventional doctrine. 323

Appearance

Li Dan is an 18-year-old Chinese man described as tall, handsome, and naturally fair-skinned. His appearance, wealth, and composed manner draw attention from classmates and strangers alike. 1 20 31

• Naturally fair complexion. 1
• Often regarded as handsome by Jennifer, Trish, Heather, and other women. 6 29 39
• Wore black camouflage Special Forces gear during the Bolehan Cave expedition. 7
• Used a custom-made Vampire costume for Halloween. 29
• Can assume monstrous forms by fusing with contained entities. 22 40
• After completing his Immortal Body, his skin, facial proportions, and physique become unnaturally flawless; even Xu Xian-jing considers his beauty almost unreal. 139 294
• In Paranormal Transformation, he retains his human appearance but becomes shrouded in an insubstantial, ghost-like aura and emits the presence of a High-Ranking Demon. 139 174
• His perfected appearance attracts excessive public attention, which he finds inconvenient because he prefers privacy and anonymity. 294 298

Personality

Li Dan is pragmatic, cautious, and strongly motivated by self-preservation. He prepares heavily for threats he expects to have physical forms, purchasing firearms, armor, explosives, lighting equipment, and protective gear before entering Bolehan Cave. 7 8 He does not trust divine protection and instead treats containment power as the only reliable defense against the supernatural. 1 4

His caution does not prevent him from taking calculated risks. Once he has sufficient resources or subordinates, he is willing to investigate lethal situations for valuable containment targets, including the Evil Spirit Wendigo, Art the Clown, and the Bat Person. 12 16 27 38

Li Dan can be ruthless toward hostile entities. He restrained and dissected Art to determine how the clown's immortality worked, continuing until Art became containable. 27 However, he also protects people he considers worth helping, including his classmates, Beth, Martin, Rebecca, and the police officers threatened by the Bat Person. 3 16 37 46

As his abilities develop, Li Dan becomes increasingly confident in facing demons, Ghost Domains, and government containment subjects. He prefers efficient containment to conventional destruction, particularly when an enemy may become a useful card, subordinate, or Fusion material. 178 323 335

He is not conventionally altruistic, but he opposes sacrificing innocent people when alternatives exist. During his negotiations with the Bureau, he criticizes its use of college students as ritual sacrifices and argues that violent criminals would be more appropriate if sacrifices are unavoidable. 260

Despite his growing authority, Li Dan remains curious about unfamiliar supernatural systems. He studies Japanese mediums, Taoist arts, Hong Kong ghost-hunting practices, the Bureau's artifacts, and Leon's belief-based methods rather than dismissing them outright. 178 203 260 312 314

Abilities & Skills

Ghost Cards

Li Dan's primary power is a deck of Ghost Cards that detects, contains, releases, commands, and fuses supernatural entities. The deck originally contains 54 cards divided into Diamond, Heart, Spade, and Club suits. 1

• Detects supernatural traces, including the Ghost Nun, Jennifer's demon, and Evil Spirit Diana. 1 19 46
• Can contain entities once they are sufficiently weakened or otherwise meet the system's conditions. 2 16 27
• Allows contained beings to be released as controllable subordinates. 3 37
• Can store equipment with a contained being if that being is capable of using it; Li Dan successfully equips a Deformed Person with an M16. 8
• Containment can fail against targets that are too powerful, undamaged, or protected by unusual traits such as immortality. 14 27
• Ability information becomes less clear as his number of contained entities increases. 50
• Diamond Ace provides a personal storage space, allowing Li Dan to conceal weapons, explosives, supplies, and other objects until needed. 50 154
• Ghost Cards can develop beyond ordinary containment ranks. The Qin Corpse King and thousands of terracotta soldiers cause a Guard Card to evolve into a King Card. 323
• The Gothic Grand Theater, Ghost Lake, Mary Shaw's mist, and the Mirror Domain can be employed as domain-like spaces to trap, suppress, investigate, or isolate supernatural entities. 57 178 286
• Following the Reshuffle, Ability Extraction is replaced by a more reliable Fusion function. Previously extracted abilities remain usable, but future growth focuses on permanent fusion and entity combination. 130

Fusion

Li Dan can fuse with a contained entity or an extracted ability, temporarily gaining its physical traits and powers.

• Deformed Person fusion — Increases strength by roughly two to three times, reduces pain sensitivity, improves recovery, and enhances vision. 3
• Evil Spirit Wendigo fusion — Grants immense physical power; Li Dan describes it as enough strength to kill Mutated Ogres casually. 16
• Terror Transformation Stage Two — Causes crimson bone spurs and bone blades to erupt from his body, dramatically improving combat power. 22
• Bat Person fusion — Gives him a bat-like form, high-speed flight, enhanced speed, and enhanced strength. Daylight causes severe discomfort and an urge to seek darkness. 40
• Immortal Body (Incomplete) — Grants high-temperature resistance and extremely rapid healing at the cost of stamina. 39 40
• Completed Immortal Body — Permanently improves Li Dan's body, resilience, recovery, physical appearance, and overall vitality. 139 294
• Paranormal Transformation / High-Ranking Demon form — Allows Li Dan to spiritualize, fly through demonic power, exhibit ghost-like intangibility, and project a terrifying demon aura. 139 174
• Hell Wendigo fusion support — Li Dan can direct the Hell Form Evil Spirit Wendigo as a major combat asset, using its Ghostfire and bone-spike body to overwhelm powerful spirits and undead armies. 130 175 322
• Demon-form possession resistance — His perfected body and internal spiritual realm make him an exceptionally dangerous host for possessing spirits. 349 350

Extracted Abilities

• Vision Enhancement — Provides limited night vision, allowing Li Dan to see paths through darkness. 4
• Limb Enhancement and Hearing Enhancement — Extracted from Wendigos after he rejected Bloodlust, Intelligence Weakening, and Evil Spirit Possession during an earlier draw. 12
• Evil Spirit Possession — An active ability extracted from the Evil Spirit Wendigo; Li Dan considers it safer than a passive possession effect because he can choose when to activate it. 17
• Immortality (Fragmented) — Drawn from the Bat Person. It grants rapid healing that consumes stamina. 39 40
• Curse Transmission — Drawn from Art. A recorded videotape can function as a marker that permits escape from a supernatural or dangerous location while it is playing. 46
• Flash Step — Drawn from Jason. It grants extremely rapid short-range movement resembling teleportation, though it requires energy and cannot pass through obstacles. 76
• Telekinetic evil power — Through Annabelle and demonic fusion, Li Dan can manipulate objects, restrain enemies at range, and exert force without physical contact. 116 154
• Ghost Lake — A suppressive black-water power capable of consuming or overpowering lesser ghostly waters, resisting Ghost Domains, and restraining spirits inside living hosts. 286 333 340

Internal Hell

Li Dan's spiritual interior functions as a sealed, hell-like prison inhabited by the terrifying entities under his control. A possessing ghost that entered his body encountered the Hell Wendigo, Art, Mary Shaw, Annabelle, and other horrors before being expelled and captured. 350

This internal realm makes possession particularly dangerous for hostile spirits, as Li Dan can remain conscious, trap intruders, and forcibly drive them out of his body. 349 350

Exorcist Status

Li Dan seeks Church recognition because an exorcist identity gives him legal and social access to supernatural cases without attracting suspicion. 34 After passing the Church's assessment with the Warrens' recommendation, he officially registers as an Exorcist. 42 43

His Church certification later grants him authority and unusual privileges, including recognition from police and access to sensitive supernatural cases. By March, he is regarded as one of the Holy See's top exorcists, and his presence has become a major source of security for Round Clam Town's wealthy residents. 97 144

Taoist and Paranormal Knowledge

Li Dan is not an orthodox Taoist, but he studies supernatural traditions pragmatically. Taoists such as Lin Ying and Uncle Feng recognize that his cultivation and supernatural command are far beyond ordinary practitioners, even while questioning the demonic nature of his methods. 201 312 323

• Learned from Lin Ying's copied inheritance after helping resolve the Fusang Ghost King incident. 205
• Is recognized by Uncle Feng as a fellow practitioner, though Uncle Feng suspects him of cultivating the Ghost Path. 312 323
• Recognizes that Leon's chocolate, plastic-wrap, and other improvised ghost-hunting techniques work because Leon's unusually powerful soul empowers his beliefs. 203 312
• Arranges for Leon to learn orthodox Taoist methods under Lin Feng, believing formal training can refine Leon's natural talent. 314

Music and Teaching

Li Dan is a capable guitarist and singer. While posing as a music teacher at Saint Noble Girls' Middle School, he performs Eason Chan's “Ten Years,” impressing the students and turning an initially inattentive class into an enthusiastic one. 315

Church Recognition and the Bat Person

Dead Silence and the Gothic Grand Theater

After Emma introduces him to a talking doll connected to Mary Shaw, Li Dan investigates the ventriloquist spirit, her fog, and the Gothic Grand Theater. Mary Shaw proves far stronger on her home ground, forcing Li Dan to use the theater's rewind function and investigate her history rather than rely on direct confrontation. 40 57 58
