Background / History

The Demon Slayer Bureau was established by the founding emperor of the Great Jing Dynasty and has operated for nearly a thousand years, with influence extending throughout the dynasty. 152

The Demon Slayer Bureau is described as the Great Jing Dynasty's most powerful department and the imperial court's “sharpest blade.” Its members kill demons and eliminate evil externally, while internally they intimidate nobles and powerful figures. The bureau may execute first and report afterward, giving it exceptional enforcement authority. 6

County Lieutenant Zhou Heng views the bureau as a force capable of challenging Qingxi County's entrenched Wang, Hu, and Liu families. He sends a recommendation to its Qinghe Prefecture branch after recognizing Mu Yang's talent. 6 16

By the time of Mu Yang's recruitment, the Qinghe Prefecture branch is headquartered roughly ten miles outside Qinghe Prefecture City in a black iron-stone complex resembling a military camp. Its buildings bear permanent dark-brown bloodstains and a heavy scent of Killing Intent. 52

The Qinghe Prefecture branch manages a Blessed Land whose limited places are reserved for martial artists under twenty-five. Branches from neighboring prefectures and other local factions compete for these places through the Blessed Land Grand Selection. 73 173

The bureau later faces growing friction with the Six Fan Gate, an imperial constabulary organization whose demon-slaying function overlaps with the bureau's responsibilities. 169 170 The current emperor's support for the newer organization and apparent willingness to disregard established conventions have raised fears that the court intends to curb, balance, or replace the bureau's longstanding influence. 152 170

Within little more than ten years of its establishment, the Six Fan Gate can rival the bureau in the prosperous Central and Cloud Provinces and has gained considerable influence in Wave, Desert, and Peak Provinces. Its recruitment of Half-Demon Lineages and imperial support subsequently give it an increasing advantage in the wider confrontation. Expansion is slower in Liang and Secluded Provinces because of their remoteness, sparse populations, limited resources, and lack of renowned Half-Demon Lineages. 170 295

The rivalry escalates into a life-threatening confrontation involving bureau members associated with the Cold Pool Blessed Land. Mu Yang's defeat of the attackers ends the immediate crisis, and Liang Qing leads the surviving group back to Qinghe Prefecture City. 191 195

Despite its reputation, the bureau is not free of internal corruption. Demon-Seeking Captains in Sancha County colluded with demons, while Anshun Prefecture Slayer Commander Ge Feiwu was implicated in demon-related wrongdoing before his death during the Ghost Lamp Temple investigation. 144 149 219 231

The bureau's declining political dominance also affects its dealings with major religious factions. Vajra Temple's connection to Thunderclap Temple complicates retaliation against it; the narrative contrasts this situation with twenty years earlier, when even Kalan Temple would not have dared obstruct bureau operations. 299

After Sheng Wu's assassination attempt against Chu Zheng, Yuan Yin arranges for Nie Chi to gather the remnants of the New Moon Hidden Sect and bring them under bureau command. Gu Changkong approves the arrangement, turning the crisis into an opportunity to subordinate the sect. 296 297 300

Organization

Major Halls

The Qinghe Prefecture branch has five major halls. 66

Hall	Function	Entry Notes
Demon Slayer Hall	Front-line demon-slaying operations	The largest, strongest, and most publicly renowned hall; nearly all recruits begin here. 66
Heavenly Crafts Hall	Forges equipment and produces artifacts	Requires forging skill. 66
Willow Leaf Hall	Treats the wounded	Requires medical expertise. 66
Internal Affairs Hall	Logistics, supplies, mission registration, approval, and merit accounting	Requires connections; operates around the clock. 66 75
Skill Transmission Hall	Oversees martial arts and manages the armory	Requires seniority. 66

Joining one of the four non-combat halls allows members to leave the high-mortality front lines and take comparatively stable positions. 66

Rank Structure

Rank	Position in Hierarchy	Requirements / Notes
Reserve Member	Probationary recruit	Passed assessment candidates remain reserves; a fourth-stage Condensing Qi Realm reserve must complete a mission to become a full member. 52
Third-Class Demon-Seeking Captain	Lowest official captain rank	Granted upon formal commissioning as a full member. 62
Second-Class Demon-Seeking Captain	Senior captain rank	Requires sufficient completed missions and accumulated merit; promotion permits members to leave their previous squad, accept missions independently, and lead teams. 62 125
First-Class Demon-Seeking Captain	Low-level executive rank	Requires both sufficient merit and fifth-stage cultivation; only a few exist in the Qinghe Prefecture branch. Qinghe has seven First-Class Captains, including Mu Yang. 62 118 132
Slayer Commander	Senior commander responsible for a bureau territory or prefectural branch	The Qinghe Prefecture Slayer Commander holds a fifth-rank official position equal in status to the prefectural governor. Slayer Commanders generally receive fixed salaries because their responsibilities restrict them from freely accepting missions. 61 211
Evil-Suppressing Deputy General	High-ranking provincial executive	Also called an Evil-Suppressing Vice General; possesses at least seventh-rank cultivation and may oversee prefectural bureau affairs. Gu Changkong retains this title despite possessing eighth-rank strength and commands the Anling Prefecture bureau. 198 259 260
Evil-Suppressing General	Senior provincial executive	Chief Evil-Suppressing Generals possess eighth-rank cultivation; within a province, they are second only to the Pacification Commissioner. 198
Pacification Commissioner	Provincial leader	Oversees a provincial Demon Slayer Bureau branch; only seven exist across the Great Jing Dynasty. 69 185
Commander	Highest bureau authority	Stationed at the imperial-capital headquarters in Central Province. 185

Official captains carry bronze identity tokens. A Third-Class token bears “Slayer” on its front and “Third Rank” on its reverse. 75

Most Evil-Suppressing Deputy Generals have territories of their own to oversee, making their reassignment to prolonged operations difficult. Gu Changkong's position as Anling Prefecture's highest bureau commander nevertheless gives him authority to direct other Deputy Generals. 259

Territory-Seeking Envoys

Territory-Seeking Envoys are specialized roaming investigators distinct from Slayer Commanders and Evil-Suppressing Generals. They answer to a provincial Pacification Commissioner, travel throughout their province, exterminate demons, and investigate major factions. Their work offers access to more and better-paying missions, but carries a substantially higher mortality risk than the comparatively stable posts held by Slayer Commanders. 222

Ordinarily, applicants must have served in the bureau for over five years, obtain guarantees from at least three Slayer Commanders or higher-ranking officers, and independently kill at least three sixth-rank demons or equivalent beings. 254

A specially appointed Territory-Seeking Envoy may receive a Black Jade Token and report directly to the Pacification Commissioner, beyond the command authority of even an Evil-Suppressing General. Such envoys are assigned exceptionally dangerous cases involving powerful demons, major factions, unexplored Blessed Lands, and provincial borderlands. 254

At Anling Prefecture, Territory-Seeking Envoys receive assignments through confidential mission rooms rather than relying solely on the public mission-selection system. 262 263

Other Units

• Black Armored Guard — The city-defense force of the Anling Prefecture bureau's Guard Hall. Every guard is a fourth-stage Condensing Qi Realm martial artist at Perfection and wears inscription-engraved pseudo-artifact armor, making the unit highly dangerous in formation. Fifth-rank guards may lead larger formations; more than one hundred fourth-rank guards under several fifth-rank leaders are said to have slain nearly ten sixth-rank martial artists. 259
• Prefectural branches — Larger branches, such as the Anling Prefecture bureau, function as self-contained cities housing active personnel, their families, descendants of fallen members, merchants, and specialized internal divisions. 259 260
• Dragon-Suppressing Camp — A bureau-controlled settlement near the main waterways of the Clearwater River and Clearwater Dragon Palace. Its western city is open to outsiders and trade, while its eastern city is restricted to bureau members whose identities have been verified. 304
• New Moon Hidden Sect remnants — Following Sheng Wu's defeat, Nie Chi is entrusted with gathering the surviving sect members, purging Sheng Wu's loyalists, and placing the faction under bureau command. 300

Recruitment and Advancement

The bureau recruits based on strength rather than age; anyone from sixteen to sixty may join if strong enough. 52 Recruitment assessments are held every ten days. 62

Assessment

Assessment Stage	Requirement
Strength test	Candidates below the fourth stage of the Condensing Qi Realm must lift a 10,000-jin stone lock overhead with each hand in turn, holding it for ten breaths per hand. 52
Combat test	Candidates must survive ten moves against the examiner. 52
Exemption	Fourth-stage Condensing Qi Realm martial artists bypass the strength test and proceed directly to combat. 52

The assessment screens out candidates with poor talent or unstable foundations, reflecting the danger of surviving as a front-line bureau member. 53

Successful candidates register as reserve members and receive temporary black iron identity tokens. Reserves may collect uniforms and equipment and claim one free Condensing Qi martial art. Members who reach the Condensing Qi Realm after joining can also claim a free combat-style martial art. 54 58

New reserves accompany official members on missions under established captains. Mu Yang and Ma Xuan are assigned to Qin Yuan's squad, while other recruits are placed under Li Xiulian. 62

Merit System

The bureau records demon kills and mission contributions as merits, which support promotions and exchanges for resources. 75

• Merits are divided into Heaven, Earth, Mysterious, and Yellow Grades, each with superior and inferior tiers. Leading the resolution of a first-tier demon threat grants a Yellow Grade Inferior merit, a fifth-tier threat grants an Earth Grade Inferior merit, and an eighth-tier threat grants a Heaven Grade Superior merit. 55
• A confirmed fourth-tier demon kill is worth one Mystic Grade Superior merit. 75
• Supporting personnel on that mission receive one secondary Mystic Grade Superior merit, equal to one-fifth of a full merit. 75
• Members may exchange merit for martial arts, equipment, and other resources through bureau facilities. 54 55
• Fourth-tier Condensing Qi martial arts generally cost one to three Mystic Grade Superior merits. Weapons, armor, precious medicines, and pills are comparatively expensive because martial arts manuals are easier to reproduce. 55
• Demon and monster corpses may be sold to the Internal Affairs Hall for merit, though members may retain them. 75
• Any demon killed during a registered mission may be reported for merit, even if it was not the mission's original target. 113
• The Merit-Appraisal Mirror records merits, manages promotions, and maintains official records. 118
• Lower-ranked Demon-Seeking Captains have no fixed salary; their income depends on the missions they complete. The bureau provides generous compensation, continuing protection, and regular visits to the families of members killed in service. 211
• Slayer Commanders receive fixed salaries, with even the lowest monthly wage equal to one superior Earth Grade merit, in addition to issued silver and food supplies. 211
• Personnel stationed year-round in wilderness areas may receive additional allowances according to their environment. 211
• During house raids, participating bureau members have priority in selecting spoils of war aside from key confiscated items. 118
• Senior officers may supplement mission rewards personally. Yuan Yin offers additional merits for Mu Yang's successful resolution of the sixth-rank underwater monster mission in Anshun Prefecture. 186
• Following the Hanging Sea operation, Gu Changkong credits Mu Yang with the kills of the Sea-wing Gull, Blood-Seeking Great-Toothed Shark, Sheng Wu, and a batch of sixth-rank monsters, awarding a total of ten Heaven Grade Inferior merits. 300

Facilities and Equipment

Branch Complex

• Built from solid jet-black iron stone, including its perimeter structures. 52
• Marked by a black-and-gold plaque reading “Demon Slayer Bureau.” 52
• Guarded by personnel in jet-black combat gear at a heavy mysterious-iron gate. 52
• Contains a martial arts arena, armory, guesthouse, and Internal Affairs Hall offices. 52 54 63 75
• Provides free training rooms near the martial arts distribution area. 56
• The Qinghe armory is centrally located and heavily guarded, while the Skill Transmission Hall oversees its martial arts and equipment stores. 54 66
• The Anling Prefecture branch is a much larger fortified settlement roughly twenty li outside Anling Prefecture City. It contains shops, restaurants, pharmacies, merchant traffic, and regular Black Armored Guard patrols. 259 260
• Anling's defenses include massive walls, arrow towers, and Mountain-Crushing Crossbows. Its ability to equip several hundred guards with pseudo-artifact armor demonstrates its substantial logistical and forging resources. 259

Anling Armory

The Anling Prefecture armory is a three-story building constructed from massive blue-black stones inscribed with unusual patterns. Its catalogs separately list martial arts, weapons, pills, secret arts, and other resources. Elder Yao serves as its caretaker. 263

Floor	Access	Available Resources
First floor	All bureau members	Resources of fifth rank and below, covering most Demon-Seeking Captain requirements. 263
Second floor	Slayer Commanders and Territory-Seeking Envoys	Resources reaching seventh rank. 263

Its martial arts collection is substantially larger than Qinghe's, including more than one hundred Meridian Clearing Methods, dozens of sixth-rank Aperture-Opening Methods, and numerous True Astral Tempering Methods. It also holds fragmentary martial-skill booklets and techniques for obscure weapons. 263 265

Mu Yang later exchanges merits for all ten available True Astral Tempering Methods, missing techniques from the Blazing Fire and Storm series, and the seventh-rank Dragon-Soaring Mountain-Breaking Mace Technique and Thunder Dragon Formation-Breaking Awl Technique. These resources contribute to his subsequent cultivation and combat development. 300 311

Standard and Special Equipment

• Black-and-red uniform — Bureau members wear black robes embroidered with a crimson “Slayer” character on the chest. The standard uniform has red-trimmed cuffs and the chest character rendered in seal script. 58 127
• Temperature-regulating belt — A standard cowhide belt inlaid with red agate; a second-tier item with a constant-temperature effect. 58
• Fluorescent Stone — Standard issue for full members; used for illumination and produced by the Heavenly Crafts Hall. 66
• Demon-Appraising Mirror — An Internal Affairs Hall artifact that determines the grade of dead demon creatures; living demons may suppress their aura, making appraisal unreliable. 75
• Merit-Appraisal Mirror — Records merits, upgrades official rank, and maintains records. 118
• Demon-Seeking Compass — A special weapon used for demon tracking; it is listed in the logistics armory and costs three high-grade Mysterious-tier merits. 62
• Black Jade Token — A special token granted to directly appointed Territory-Seeking Envoys, signifying direct responsibility to the provincial Pacification Commissioner. 254
• Black Armored Guard armor — Inscription-engraved pseudo-artifact armor that combines three basic inscriptions with one low-grade inscription. Nearby suits resonate at the same frequency, distributing damage among the guards and greatly strengthening their collective defense. 259

Operations

The Demon Slayer Bureau dispatches teams to investigate civilian reports of demonic activity, such as the suspected spider demon case at Wu Family Village. 64

Not all missions originate from public informants. Some are formed from demon traces discovered and reported by Demon-Seeking Captains who lack the time, combat ability, or tracking methods to resolve them personally. 102

Teamwork is intended to compensate for gaps in individual knowledge and specialized skills. Qin Yuan emphasizes that even a powerful individual cannot master every discipline, making cooperation important in investigations and demon hunts. 102

Operations may involve cooperation with local constabularies, including blockades and coordinated raids against groups suspected of colluding with demons. 126

The bureau's authority carries substantial weight among local officials and constables; in Sancha County, corrupt constables immediately surrender after recognizing Mu Yang's bureau uniform. 142

The bureau manages the Qinghe Prefecture Blessed Land and organizes its Grand Selection, dividing entrants into fourth-tier and fifth-tier groups and appointing a First-Class Demon-Seeking Captain as an impartial judge. 73 173

Mysterious-grade missions may be selected through the Internal Affairs Hall, but Earth-grade missions involving fifth-rank demons are generally assigned directly because First-Class Demon-Seeking Captains are scarce. Immediate threats from lower-rank demons may likewise be prioritized or directly assigned by a Deputy Hall Master. 131 132

First-Class Demon-Seeking Captains may undertake external assignments, whereas lower-ranked captains ordinarily lack that qualification. 144

The bureau investigates internal and external collusion with demons, including corrupt officials, powerful clans, martial arts factions, and its own members. Its Anshun and Anling Prefecture personnel jointly investigated the disappearances of Shunyuan River personnel, the missing Slayer Commanders Fu Yu and Ge Feiwu, Ghost Lamp Temple, and Medicine King Valley. 149 211 219 222 239

Although the bureau historically handled matters such as investigating officials, suppressing martial arts factions, and regulating military armament trade, many of these functions have been curtailed or taken by the Six Fan Gate. 239 244

Large-scale confrontations with human factions remain unusual compared with routine demon-slaying work. Bureau personnel also consume enormous quantities of demon meat to support recovery, limiting the availability of corpses and other resources for redistribution. 244 265

In Anling Prefecture, newly discovered sixth-rank monsters are generally hunted by cooperating bureau personnel. Unresolved assignments often concern recent discoveries or monsters whose mobility, elusive abilities, or defensive advantages make them difficult for ordinary Territory-Seeking Envoys to capture. Mu Yang selects the Violet Lightning Bat Demon mission from such assignments. 262 263

Windcloud Sect Surveillance

Gu Changkong chooses to use Windcloud Sect as bait rather than destroy it immediately, hoping to expose stronger enemies connected to the Six Fan Gate. The sect's prior opposition to the bureau and submission to the rival organization make it a surveillance target, while events surrounding the Blessed Land Grand Selection provide grounds for action. 259

Yuan Yin is assigned to monitor Windcloud Cliff's only entrance and track Sect Master Yun Qianzhong, a sixth-rank Perfection martial artist, and Grand Elder Feng Lie, an early sixth-rank martial artist. The bureau sets a one-month deadline for possible Six Fan Gate intervention; if no one appears, the plan is to attack and capture both leaders alive. Mu Yang is permitted to undertake a separate sixth-rank monster mission before joining the operation. 262

Vajra Temple Gate Confrontation

Master Xuyuan brings Vajra Temple disciples to the Anling bureau's gates, demanding an explanation for Mingjing's death during the Ghost Lamp Temple incident. He refuses an invitation to discuss the matter inside, obstructs traffic, and attempts to pressure the bureau publicly. Lu Zongsong claims responsibility for the killing, while local residents defend his character by recounting his demon-slaying and relief work. 283

Gu Changkong intervenes when Xuyuan attempts to attack Lu Zongsong and exposes the involvement of Xiao Yu, an eighth-rank Six Fan Gate Gold Token Constable. Gu Changkong's ensuing battle with Xiao Yu lasts an hour and damages the bureau's surrounding walls through its shockwaves. After driving Xiao Yu back, Gu Changkong orders free medical treatment for those affected. 283 285

Lu Zongsong's admission is subsequently revealed to have shielded Mu Yang, the actual killer of Mingjing. Gu Changkong, Yuan Yin, and Mu Yang discuss the possibility that Vajra Temple may retaliate by hiring the New Moon Hidden Sect to assassinate bureau members. 285

Hanging Sea Ambush and New Moon Hidden Sect Submission

Nie Chi warns Yuan Yin that Sheng Wu, the New Moon Hidden Sect's leader, intends to assassinate Evil-Suppressing Deputy General Chu Zheng at Hanging Sea Camp. He also reveals that the Six Fan Gate has secretly supported Sheng Wu's rise. Gu Changkong dispatches Yuan Yin and Gu Tingquan as reinforcements. 296

Sheng Wu ambushes Chu Zheng while the latter pursues a seventh-rank Sea-wing Gull. Chu Zheng's armor prevents the initial throat strike from killing him, but the assassin and monster attack together, revealing that the Gull's repeated appearances were part of a deliberate trap. 296 297

After the operation, Yuan Yin directs Nie Chi to recover the sect's remnants and place them under bureau command. Nie Chi agrees to purge Sheng Wu's loyalists, and Gu Changkong approves the plan. Mu Yang receives a substantial merit award for the operation's kills. 300

Relationships

• Great Jing imperial court — The bureau serves as an imperial enforcement and demon-slaying institution. 6
• Qinghe Prefecture Constabulary — Cooperates with the bureau during major operations, including the raid on the Water Transport Gang. 126
• Six Fan Gate — A rival or overlapping imperial force created to monitor officials and kill demons; its members increasingly challenge bureau personnel. The Six Fan Gate has received strong imperial support and has become openly hostile to the bureau in Liang Province. Intelligence received by Yuan Yin further identifies its leadership and many personnel as half-demons. Its ordinary constables are largely recruited from traditional constabularies, while Half-Demons are concentrated among elite and higher-ranking personnel. Xiao Yu supports Vajra Temple's challenge at the bureau gates, and the organization secretly backs Sheng Wu's rise within the New Moon Hidden Sect. 169 170 185 186 194 283 296
• Heavenly Crafts Hall — A bureau hall responsible for forging equipment and producing artifacts such as Fluorescent Stones and the Demon-Appraising Mirror. 66 75
• Mu Yang — Recruited through Zhou Heng's recommendation, first becoming a reserve member before rising through the Demon-Seeking Captain ranks. He later receives direct appointment as a Black Jade Token Territory-Seeking Envoy under the Liang Province Pacification Commissioner. Gu Changkong supports him with a powerful body-tempering martial art and substantial mission rewards, while bureau armory resources contribute to his advancement to seventh-rank Perfection. 16 54 75 118 127 254 261 300 311
• Yuan Yin — Initially Slayer Commander of the Qinghe Prefecture bureau and disciple of the Liang Province Pacification Commissioner. He oversees the Qinghe Blessed Land Grand Selection and supports Mu Yang's advancement. He later becomes an Evil-Suppressing Deputy General, participates in the response to the Hanging Sea assassination plot, and arranges the New Moon Hidden Sect's submission. 173 185 254 296 300
• Gu Changkong — An eighth-rank Evil-Suppressing Deputy General and the highest bureau commander in Anling Prefecture; Yuan Yin's senior martial brother and Lu Zongsong's master. He directs the Windcloud Sect operation, protects bureau personnel during the Vajra Temple confrontation, and approves bringing the New Moon Hidden Sect under bureau command. 259 260 262 283 285 300
• Xu Xinghe — Master of Gu Changkong and Yuan Yin and creator of the seventh-rank Four Spirits Four Symbols Demon-Suppressing Body. Gu Changkong gives the technique to Mu Yang and offers protection against monster factions attracted by its cultivation. 261
• Lu Zongsong — An Anling Prefecture Territory-Seeking Envoy and disciple of its Evil-Suppressing General. He collaborates with Mu Yang during the Ghost Lamp Temple and Medicine King Valley investigations. His master is later identified as Gu Changkong. Lu Zongsong assumes responsibility for Mingjing's death to protect Mu Yang and enjoys strong public support for his demon-slaying and assistance to distressed communities. 222 224 239 283 285
• Gu Lingyun — A First-Class Demon-Seeking Captain from Anling Prefecture who participates in the Ghost Lamp Temple investigation under Lu Zongsong. 221 222
• Chu Zheng — A veteran Evil-Suppressing Deputy General targeted by Sheng Wu and the Sea-wing Gull at Hanging Sea. His armor saves him from the initial assassination strike, and the bureau sends reinforcements after receiving Nie Chi's warning. 296 297
• Gu Tingquan — A bureau officer involved in the Medicine King Valley investigation and later dispatched with Yuan Yin to reinforce Chu Zheng. 244 247 296
• Nie Chi — A human former Six Fan Gate Silver Token Constable and expelled New Moon Hidden Sect disciple. After being cast out of both organizations, he warns the bureau about Sheng Wu's assassination plot and accepts responsibility for gathering his former sect under bureau command. 186 296 300
• Medicine King Valley — A major martial faction investigated for human experimentation, trafficking, and suspected connections to Ghost Lamp Temple. Its members ultimately clash with Mu Yang and Lu Zongsong. 222 239 240
• Ghost Lamp Temple — A powerful religious faction investigated over its suspected links to Ge Feiwu, Fu Yu's disappearance, human trafficking, and demon-related crimes. 219 220 222
• Vajra Temple — Ghost Lamp Temple's powerful religious connection and a source of retaliation after Mingjing's death. Abbot Xuyuan confronts the bureau with Six Fan Gate support. Its status as a branch founded by Thunderclap Temple's Vajra Courtyard complicates direct bureau action against it. 219 283 285 299
• New Moon Hidden Sect — An assassin faction whose ancestral law forbids attacks on the Demon Slayer Bureau. Sheng Wu violates that prohibition by plotting against Chu Zheng with Six Fan Gate support and colluding with a Monster King. After his defeat, Nie Chi undertakes to purge his followers and bring the sect's remnants under bureau command. 296 297 300
• Windcloud Sect — A faction that pledged allegiance to the Six Fan Gate amid the growing conflict between the two imperial forces, making it a target of bureau scrutiny. Gu Changkong plans to use it as bait to draw out stronger enemies before capturing its leaders. 259 262
• Clearwater Dragon Palace — A powerful aquatic monster faction near the bureau's Dragon-Suppressing Camp. The camp attracts high-rank monster hunters and merchants trading in aquatic monster materials. 304
