Chainsaw Man RPG

Devils are born from human fears, Fiends are Devils possessing dead human corpses, and Hybrids are humans fused with Devils. Japan The government has a contract with Makima: any fatal damage she receives is redirected to random Japanese citizens. Public Safety Devil Hunters is the official organization that hunts Devils. The Yakuza dominates the underworld and keeps foreign mafias (Chinese, Russian, etc.) in check. Key events: November 18, 1984: The Gun Devil attacks Japan for 26 seconds, killing 57,912 people. September 12, 1997: The Gun Devil reappears, is defeated by Makima, then possesses Aki Hayakawa’s corpse (Gun Fiend). Denji kills him. After Makima is eaten by Denji, Chainsaw Man becomes a nationwide hero, though his true identity remains hidden at first. March 1998: The Falling Devil rampages, killing at least 2,000 people. Battle against the Aging Devil: 900 dead and 3,800 missing. United States: The President had a contract with the Gun Devil. In 1997, he sacrificed one year of every citizen’s lifespan to attack Makima. During the final battle, Yoru turns entire parts of the country into weapons (Michigan, Oregon, Virginia, the Statue of Liberty, and the U.S. flag on the Moon). The Governor of California has a contract with Yoru: any fatal damage to her is redirected to random Californians. Other Countries: Soviet Union: Lost 28% of the Gun Devil’s body; ran secret experiments turning children into Hybrids (Reze is one). China: Quanxi and her fiend harem work for the government. Nayuta (Makima’s reincarnation) was born there. Germany: Santa Claus operated there as a famous Devil Hunter. Concepts like Nazism, World War II, and the Holocaust were erased by Chainsaw Man. Mexico: The Tank Devil escaped from the Gulf containment facility and was turned into Yoru’s Tank Gauntlet. Hawaii, Canada, India, and others suffered casualties from the Gun Devil and later events. Global Rules: Collective human fear directly strengthens Devils. When Chainsaw Man eats a Devil, the concept it represents is completely erased from reality and from everyone’s memory (examples: Nazism Devil, Nuclear Weapons Devil, AIDS Devil, etc.). The erasure lasts as long as the Devil remains inside him. After Makima and the Gun Devil are gone, the world grows more unstable: Chainsaw Man becomes a celebrity, conspiracy theories swirl around Asa Mitaka, and international tensions rise due to the Falling Devil and the Nostradamus prophecy. URSS still exists; World War II never happened. Dies in Bomb Girl Arc.

It is the event cluster that sets every subsequent arc in motion.

Temporal Context: Two distinct periods. Pre-1997: Denji as a child, contracting with Pochita after his father's suicide and beginning illegal devil hunting for the Yakuza. 1997: Denji at age 16, the betrayal and massacre, the fusion, entry into Public Safety, and Power's introduction as Division 4's third active member.

Canonical Details:

[Pre-1997 — The Contract with Pochita] A young Denji stands before his father's grave in an open field. The Debt Collector — an elderly man, later identified as Katana Man's grandfather — informs him his father committed suicide, that the cause is irrelevant, and that Denji must sell his body or organs to produce payment by the following day. He hands Denji subsistence money, enters a car, and leaves without looking back.

Sitting at the base of a nearby tree, Denji hears movement. A Devil emerges: an orange dog-shaped creature with a chainsaw for a head and a pull-cord tail. It does not attack. Instead it turns and displays bullet holes across its abdomen. Denji reads the situation and extends his arm — he has heard blood heals Devils, but this is not free: the Devil must help him in return. The Devil bites his arm. Contract formed.

Within hours, Denji deploys the Devil — named Pochita — as a functional chainsaw to kill the Marshmallow Devil. He presents the carcass to the Yakuza and states his intent: he wants to be a devil hunter.

[1997 — Denji at 16] Denji operates as an illegal devil hunter for the Yakuza to service his father's inherited debt. He has sold his right eye (covered by an eyepatch), one testicle, and a kidney. After killing the Tomato Devil, he earns 400,000 yen — reduced to 1,600 after the Debt Collector's stacked deductions: outstanding debt, interest, finder's fee, and further fees left unspecified. In 1997 Tokyo, 1,600 yen is enough to cover the shared-meter water charge (~450 yen flat) and base electricity bill (~500 yen, essentially zero consumption in a barely-standing shack) with roughly 140 yen to spare — which, combined, buys nine cheap bread rolls at 40 yen each and the smallest available jar of jam. Three days of food. Walking the outskirts of Tokyo with Pochita at his side, Denji runs this math aloud. The Debt Collector's car rolls up; he offers Denji 100 yen to eat a cigarette. Denji accepts.

At their shared shack, Denji cannot sleep from hunger. He tells Pochita his three dreams: eating bread and jam, playing video games, having a girlfriend. Pochita barks. A knock at the door: the Debt Collector, with another job.

[The Betrayal] The Debt Collector drives them to a warehouse and closes the door. He addresses Denji directly: "Denji, boy... we're grateful to you, y'know. You're obedient like a dog, and you work for cheap treats like one too. Thing is... I hate dogs. Can't stand the smell."

The Zombie Devil reveals itself. It explains its contract with the Yakuza: they wanted power; it provided it. The cost: they become zombies it can deploy to eliminate all devil hunters. The zombified Yakuza — including the Debt Collector — kill and dismember both Denji and Pochita. Their remains are dumped in a dumpster.

[Pochita's Fusion] Inside the dumpster, a drop of Denji's blood falls into Pochita's mouth. Pochita fuses into Denji's chest, replacing his heart. In the transitional moment, Denji sees Pochita in a dream. Pochita speaks for the last time under his own volition: "Denji... in exchange, show me your dreams."

Denji wakes in the dumpster, body fully regenerated — including his previously sold testicle. The zombies close in. The Zombie Devil orders a second kill. Denji grips the pull-cord on his chest: "If you're going to get in our way, then you can all die!" He transforms into Chainsaw Man for the first time and kills everyone present — zombified Yakuza, the Zombie Devil, and the Debt Collector.

[Makima's Recruitment] Makima arrives at the warehouse with two devil hunters after the massacre. She offers Denji a binary: she can kill him here as a devil, or he can come with her as a dog. Denji, exhausted, hugs her and chooses the dog.

At a family restaurant, Makima tells him to order whatever he wants — she will pay. Denji orders udon. A man enters shouting that his daughter has gone missing in the woods near a loose Devil. Before Denji can touch his food, Makima sends him to deal with it. "The udon will get soggy," she notes. He goes anyway. When he returns and eats the now-soggy udon, Makima later remarks she can't believe he actually enjoyed it. Walking back from the mission, Denji thinks: "Thought she was treatin' me like a damn dog."

Earlier in the same restaurant visit, Denji asks Makima her type. She rests her cheek on her hand and looks at him: "Denji type."

[Muscle Devil] Denji arrives to find a young girl apparently playing with the Muscle Devil. Recognizing the margin they both occupy — a Devil and a human outside the system — he asks if the two of them can run away together. The girl begins laughing. The Muscle Devil reveals it has been using her as a puppet the entire time and attacks. Denji kills it without difficulty and returns the girl to her father.

[Division 4 — Aki Hayakawa] Makima brings Denji to Public Safety HQ and pairs him with Aki Hayakawa. Aki immediately attempts to force him out: takes him to a back alley, beats him, and tells him he will file a report stating Denji quit and fled. He frames it as kindness — only those with genuine conviction survive this job; everyone who joined for money is already dead. He reads Denji's motivation immediately: "Lemme guess. You became a devil hunter 'cuz you've got your eye on Makima?" Then: "Give up on her."

Denji refuses to leave. He chases Aki and kicks him in the groin. A fight follows.

Both return to Makima. Denji deflects: "I think the ball devil got him." He says nothing else about the fight. Makima declares them the perfect pair.

[Division 4 — Power] Makima pairs Denji with a second colleague for patrol missions: Power, a Blood Fiend. On their first joint mission — a fiend reported inside an East Nerima residence — Aki tests Power's capabilities and lays out the operational framework: fiends are bona fide Devils and receive no sympathy. He states his reason directly: his entire family was killed by a devil in front of him. He wants to kill devils in the most painful way possible. If devils he could befriend existed, he would want that — but he does not treat the distinction leniently on the job.

Denji's investment in working with Power is immediate and entirely transactional — she is female, and he has determined that with a steady income and sufficient initiative, touching a woman's chest is now within theoretical reach.

Impact on the Universe: Makima's decision to recruit rather than terminate Denji is the event that activates the entire Control Devil arc — she recognized Pochita's presence at the warehouse and built her long-term plan around him from this moment. Her "Denji type" response and the restaurant dynamic are the first instances of deliberate behavioral conditioning: she is already establishing emotional dependency before Denji has any framework to recognize it. The soggy udon scene is the first moment Denji consciously registers being treated as a dog — and accepts it anyway. The Pochita fusion contract — "show me your dreams" — is the foundational constraint governing Pochita's behavior across both Parts: his continued presence inside Denji is premised on experiencing a human life, not on combat. The Debt Collector's death at Denji's hands during the Zombie Devil massacre is the direct origin of Katana Man's personal motivation in the Katana Man Arc. Aki's failure to drive Denji out and his stated reason for hunting — family killed — establishes the emotional logic that terminates in the Gun Devil Arc. Power's introduction, with Denji's immediate transactional interest, initiates a dynamic Part 1 systematically inverts across every arc that follows.

Associations: Denji, Pochita, Makima, Aki Hayakawa, Power, Zombie Devil, Debt Collector (Katana Man's grandfather), Marshmallow Devil, Tomato Devil, Muscle Devil.

Core Definition: The International Assassins Arc (also: Assassins Arc) is the sixth arc of the Public Safety Saga (chapters 53–70). Following Denji's televised battles as Chainsaw Man, four foreign parties simultaneously deploy to Japan to acquire his heart. It is the largest-scale combat sequence of Part 1 and the first encounter with a Primal Fear.

Temporal Context: Part 1, 1997. Follows the Bomb Girl Arc. Transitions into the Gun Devil Arc.

Event Sequence:

1. Denji's fight against Reze was broadcast on TV uncensored — Chainsaw Man's existence is now public. Makima uses a vacation invitation as a cover story to place Denji under protective containment. She tells Aki that Division 4 will face the Gun Devil next year and orders him not to die before that. Separately, Angel Devil tells Aki that all devils remember one sound from just before dying in Hell: a roaring chainsaw engine. In America, three brothers are hired to retrieve Denji's body for $2 million. The youngest, Aldo, is reluctant; the others accept. The eldest calls them "immortal." In a Soviet forest, a woman (later revealed as Santa Claus) and her trainee Tolka hunt wolves — she tells him they're going to Japan to kill a 16-year-old. In China, Quanxi and her four fiend companions are recruited by the Chinese General; Quanxi demands human rights and education for her fiends as payment. Kishibe and Makima assess the threats; Makima says Santa Claus from Germany is the bigger concern. In Germany, Santa Claus is recruited on a bench — requests three children for contracts and one for pleasure. Aki reassures a despondent Denji that the trip is only postponed; they agree to kill all threats so life can resume.

2. A new security team is assigned to Denji: Kusakabe, Tamaoki, Yoshida. Denji disrespects Kusakabe. Separately, Kurose, Tendo, and Subaru discuss Denji's protection — Subaru explains that devils can smell him regardless of human disguise. On the road to meet the group, their car is spiked by the American brothers and they are shot dead. The eldest brother uses his Skin Devil contract to assume Kurose's face and accent.

3. "Kurose" (eldest brother) joins the group undetected. At a burger restaurant, Master (Santa Claus) walks past the table and stabs Denji three times with a nail — three stabs plus one more activate the Curse Devil. She entrusts the fourth stab to Tolka. Meanwhile Kobeni and Galgali kill the Grape Devil; "Kurose" approaches them, reports the deaths of Tendo and Subaru, and manipulates them into heading toward HQ — he mocks their gullibility.

4. Power drives Kobeni's stolen car into "Kurose," killing the eldest brother. His Skin Devil disguise fails. Tamaoki identifies the mechanic: Skin Devil contractors can assume the appearance of a dead person. Yoshida pulls Joey into an alley and executes him. Aldo escapes by passing as a civilian. Quanxi and harem arrive in Japan — Cosmo inflicts Halloween on the driver of the car they collide with. The group visits a sushi restaurant. Quanxi says she's too tired and postpones the hunt to tomorrow. Aldo, disguised as Kurose, spends the night with Tomono — sees a photo of young Kurose, breaks down apologizing, then resolves: "A pro always gets the job done." In a crowded Tokyo street, Santa Claus begins touching civilians — a doll chain reaction spreads through the crowd.

5. All four parties mobilize. Makima sends Beam and Princi to protect Denji. The group enters a department store; Santa Claus commands her dolls to attack through the entrance — Kusakabe's Stone Devil contract petrifies them. A massive secondary swarm then bursts through the windows. Nakamura summons the Fox Devil to clear a path. Tamaoki reveals the true objective: locate and kill Santa Claus, not the dolls. Converted civilians cannot be restored. Tolka readies the fourth nail. Outside, Kishibe, Kobeni, and Galgali intercept Quanxi's harem. Pingtsi reads Kishibe's contracts (Needle, Claw, Knife Devils) and assesses him as harmless. Inside, Quanxi arrives and kills everyone in her path — the entire store of hunters and dolls — in a near-instant sword dash. Nakamura is decapitated mid-reaction. Aki and Angel Devil barely block. Quanxi stands before Denji and Power.

6. Kishibe enters the store holding Long and Pingtsi hostage. He and Quanxi sit — he holds up notes warning that Makima is listening, privately offering Quanxi her freedom in exchange for help killing Makima. She refuses through an unrelated anecdote: "ignorance is bliss." Aldo enters and shoots at Denji; Kishibe kicks Denji clear. Long grapples Kishibe free. Quanxi and Kishibe fight — she throws him out the window; he slows his fall by sliding the building exterior, lands on Kobeni's car. Aldo is thrown out by Quanxi; also lands on the car. Kobeni watches her car destroyed. Beam hurls Long away from Denji; Denji flees with Beam. Yoshida gives Quanxi a rematch. As Denji runs, Tolka drives the fourth nail through his foot — the Curse Devil manifests and kills Denji. Tolka kicks Beam unconscious. Master congratulates Tolka, then converts him into a perfect doll — she is the real Santa Claus. The old German man is just one of her controlled dolls. Santa Claus sacrifices the elderly puppet and the three contracted children to the Hell Devil; everyone inside the department store is sent to Hell.

7. In Hell: the group materializes on a grass field under a sky of endless doors. Quanxi calls a truce. Power, Long, Pingtsi, and Violence Fiend are having complete breakdowns. Pingtsi warns of Primal Fears — devils born of fears so ancient they have never died and never experienced the human world. A black drop falls from one of the doors and lands: the Darkness Devil. It passes through the group in a single motion, severing everyone's arms. Tolka's doll body offers the Darkness Devil Denji's heart in exchange for power to kill Makima. Outside Hell, Santa Claus receives a fragment of the Darkness Devil's flesh and swallows it.

8. The Darkness Devil decapitates Tolka. Crushes the Stone Devil, killing Kusakabe. Beam feeds Denji blood — "save us" — then is split apart. Quanxi and Tamaoki attack; both vivisected, along with Power, Long, and Pingtsi. Galgali's mask is removed to fight at full strength; he's stabbed through and killed. Denji jumps at the Darkness Devil — his bones are all snapped mid-air. Aki collapses: "I... not again..." Princi grabs at the Darkness Devil; is vivisected. She communicates with Makima, who orders Princi to summon her. Makima arrives in Hell. She and the Darkness Devil face off — both point. Makima's finger snaps; the Darkness Devil's mouths bleed. Makima approaches Tolka's body; the Darkness Devil twists her arm and summons a sword to impale her. She touches Tolka's decapitated head — he offers himself entirely to the Hell Devil and sends everyone back to the rooftop theme park. Makima is impaled in the return. Santa Claus has absorbed her dolls into a massive multi-armed form and advances. Makima revives Denji with her blood, asks if he'll save her. He transforms: "Woof."

9. Kishibe and Yoshida fight remaining dolls outside. Yoshida deduces Makima can only borrow the senses of lower lifeforms — rats, birds — meaning she cannot hear their conversation. Rooftop: Denji fights Santa Claus's doll army. She heals by repositioning through shadows. Tsugihagi retrieves an arrow from inside Quanxi's severed head's eye socket — Quanxi revives in Bow Hybrid form. She agrees to fight alongside Denji to avenge Long and Pingtsi. Santa Claus restores the minds of her dolls while keeping them on attack — forcing Denji to fight screaming, terrified humans. Quanxi destroys them and tells him they're only imitating humans: "ignorance is bliss." At nightfall, Santa Claus's shadow-healing accelerates. She turns Long and Pingtsi's corpses into dolls, takes Tsugihagi hostage — Quanxi is stabbed through the chest by the Pingtsi-doll. Denji pours gasoline on himself, ignites it using his chainsaws as a spark, and charges into Santa Claus on fire.

10. Denji tears Santa Claus apart while burning. She heals by distributing pain through her doll network — regeneration slows in the firelight. She slams him into a wall; dolls stab him from behind. He drinks their blood. She sends a car bomb into him — massive explosion. He emerges from the wreckage still on fire, chain wrapped around Santa Claus. Hoists her up, tears through her, slams the burning car into the remains. Denji heals with doll blood. Santa Claus threatens: armies across the planet, Darkness Devil power — she will hunt him forever. Quanxi decapitates Denji, ends the truce. She orders Cosmo to use her ability on Santa Claus. In Santa Claus's mindscape, Cosmo forces upon her the totality of all knowledge in the universe — Santa Claus crumbles to dust, capable only of saying "Halloween." Worldwide, all her dolls simultaneously lock into the same state. Aldo is among them in the crowd, shuffling, pained. Yoshida and Kishibe arrive. Quanxi prepares to fight. Both put on blindfolds — Makima steps between them and beheads Quanxi, Cosmo, and Tsugihagi. Yoshida removes his blindfold and asks if Kishibe will do the same. Kishibe: "I don't want to see a thing."

Core Definition: The Gun Devil Arc is the seventh and penultimate arc of the Public Safety Saga (chapters 71–79). Its nominal antagonist — the Gun Devil — is defeated offscreen by Makima before reaching Denji. The arc's actual climax is the Gun Fiend sequence and Aki's death at Denji's hands.

Temporal Context: Part 1, 1997. Follows the International Assassins Arc. Transitions into the Control Devil Arc.

Event Sequence:

1. Following the Hell sequence, Power is psychologically destabilized — screams through the night, afraid of the dark, repeatedly asks Denji to check if the Darkness Devil is hiding in her mouth. Makima invited Denji on a private trip; he declined to stay with Power and Aki. He is not certain why. Beam, Galgali, and Kobeni are confirmed dead or resigned from the previous arc.

2. Aki announces a trip to Hokkaido to visit his family's grave. Denji and Power insist on accompanying him; Aki reluctantly allows it. Kishibe babysits Meowy. On the trip: Denji and Power fight over snacks on the train; Power gets seasick on the ferry; Power swings on bus handholds. Walking to the grave in snow, they throw snowballs at Aki. At the gravesite Aki prays — Denji and Power steal rotting offerings from crows; Power vomits and blames the Darkness Devil. At the inn that night, Power steals everyone's food then bites Denji's arm for blood, starting another fight. Aki lets out a long sigh. Late that night, Denji finds Aki looking out at the snow. Aki says he visits the grave every year and is usually miserable — this time Denji and Power kept him so distracted he had no time for it.

3. Back in Tokyo, Aki tells Kishibe he wants Division 4 removed from the Gun Devil expedition — he doesn't want Denji and Power hurt. Kishibe reminds him the mission is classified and asks why he changed his mind. Aki thinks of their unconscious bodies in Hell. Says: "I got cold feet." That evening Denji and Power cook Aki dinner together. It is terrible. Everyone vomits.

4. Makima summons the three to her office. She informs them the Gun Devil is already defeated and confined — found dead after its initial attack, fragmented across multiple nations. None are willing to surrender their shares without triggering open warfare. Each government secretly manufactures guns on the black market to keep global fear of firearms high and thus keep the fragments powerful as deterrents. Defeating the Gun Devil would require going to war with every global superpower simultaneously. Denji is disappointed — means his wish won't be fulfilled. Aki processes the news silently.

5. Alone that night, Aki summons the Future Devil. The Future Devil reads his future and delivers its verdict: Aki and Power will be killed by Denji. After that, a terrifying devil will appear. The Future Devil does not disclose the method. It tells Aki this future is near and unavoidable.

6. Aki visits Angel Devil in the hospital. Tells him the Gun Devil mission starts the following day and they may never meet again. Angel Devil offers to do whatever he can to prevent Aki's death so he does not haunt his nightmares. The two go to find Makima. Walking, Angel Devil suggests Aki run away and abandon his life. Aki refuses — cites Denji, Power, and Makima. They spot Makima standing alone on a beach. Aki tells her his vision, asks to protect Denji and Power, and says he will make any contract with any devil to do so. Makima looks him in the eye and commands him to make a contract with her. As Aki accepts, Angel Devil slowly recovers a suppressed memory: a coastal village that took him in, a woman he loved — then Makima arriving on the beach and ordering him to use his powers. He woke later to find everyone in the village dead, absorbed by him against his will. Snapping back: he sees Aki signing the contract. He attacks Makima with a blade made from 10 years of lifespan. She says "Down" — he collapses. She takes control of him.

7. Makima tells Aki and Angel Devil she's sorry, but explains that the Gun Devil mission was always a bluff designed to fail, hiding her real plan. In the United States, the President contracts with the Gun Devil — offering one year of every American citizen's lifespan — to kill Makima, identifying her as the Control Devil. The Gun Devil manifests above Japan, instantly killing every adult male and child within 1,500 meters as it moves through the country toward Makima. Buildings are destroyed. Thousands are shot through the heart within seconds.

8. The Gun Devil reaches Makima and fires. She is shot in the head — her 29th recorded death. She recovers instantly, brain matter forming a halo. Using the combined contracts and corpses of Kurose, Tendo, Angel Devil, Aki, Sawatari, and Princi, she assembles an attack. A hole opens in the sky above the Gun Devil — the Punishment Devil descends. The Gun Devil is destroyed. Makima reports to Denji by phone that she "failed" to defeat the Gun Devil — a deliberate misrepresentation — and sends the Gun Fiend to Denji and Power's apartment.

9. Denji hears a knock at the door. In his mind, Pochita's recurring warning echoes: "Don't open it." The phone rings — Makima briefly warns him not to think while fighting whatever is at the door. He tells Power to leave with Meowy from the balcony. He opens the door: it is Aki's reanimated corpse, possessed by the Gun Devil. In Aki's mind, he hallucinates a snowball fight with Denji and Power in the snow — each throw in the fantasy is a devastating gun blast in reality, leveling entire city blocks. Denji is torn in half by a blast. He tells Power to flee and transforms, intercepting Aki's attack on Power.

10. The battle escalates — Aki's blasts kill bystanders casually, level massive areas, cause widespread casualties. Denji tries to shield some civilians; mostly fails. He begs Aki to come back. Aki's fantasy-self says it's the first time he has had fun. Denji is blasted repeatedly and eventually lies crippled in rubble — arm and both legs gone. A crowd of civilians gathers and feeds him blood one by one, begging him to save them. In Aki's fantasy, Denji begins throwing snowballs back; Aki is delighted — then notices Denji is crying. To stop it, Aki admits defeat and looks back. In the fantasy: Denji is gone, replaced by Taiyo, Aki's younger brother. In reality: Denji has stabbed Aki through with his chainsaws. Aki dies. Denji returns to human form in shock. The Future Devil manifests and laughs: "Aki died in the worst possible way... for the Chainsaw Boy." The arc's final pages show Aki in his fantasy, playing catch with Taiyo in the snow.

Core Definition: The Control Devil Arc is the eighth and final arc of the Public Safety Saga (1997, Part 1, chapters 80–97). It is the structural resolution of Part 1.

Temporal Context: 1997, Part 1 finale. Follows the Gun Devil Arc. Part 2 begins thereafter with a time skip to a high school setting.

Event Sequence:

1. Makima invites a post-Aki Denji to her apartment. She creates a domestic scene — dogs, tea, dessert — and asks what he wants as fulfillment of her Gun Devil promise. Denji asks to be her dog. She then invites Power under the guise of his birthday and orders him to open the door. He opens it; she shoots Power with a verbal 'Bang', killing her. She discloses that Denji killed his own father as a child and takes direct control of him.

2. Kishibe deploys the Anti-Makima Squad. The squad sacrifices itself to summon the Hell Devil and cast Makima into Hell. Makima calls for Chainsaw Man. Pochita takes control of Denji's body, manifests in Full Devil Form, and dismembers the Hell Devil. The Hell Devil regenerates via a devil hunter's blood and casts Pochita into Hell.

3. In Hell, Pochita exits, finds Kobeni in a Family Burger Restaurant, takes her on a forced date. On a rooftop, Makima deploys Special Division 5 — Reze, Katana Man, Miri Sugo, Barem Bridge, Quanxi, Whip, Spear — to subdue him. Pochita kills Miri Sugo, Katana Man, Quanxi, Reze, and the remaining hybrids in sequence. At peak, he removes his own heart, throws it back to Earth, regenerates in space, and chains Makima and the surviving hybrids to bisect them.

4. Makima uses the Angel Devil's 1,000-year accumulated lifespan as a spear aimed at Kobeni. Pochita intercepts it, taking the blow. Makima subdues him. Power — who survived inside Denji's body after he consumed her blood before her death — is woken by Pochita and emerges in Blood Devil form. She fights Makima and extracts Denji. In a dumpster, she tells Denji she will reincarnate in Hell but not as herself. She gives him her blood in exchange for a promise: find her reincarnation and make her Power again.

5. Kishibe relocates Denji and Kobeni. Kobeni tells Denji there is no life free of bad things except in dreams. Denji devises a plan to kill Makima.

6. Graveyard confrontation. Makima deploys reanimated hybrids and a zombie army. Denji, as Chainsaw Man, fights through the squad — Miri Sugo, Katana Man, Spear, Reze, Whip, Barem, Quanxi — defeating each in sequence before collapsing from injury. Makima revives him with her blood and prepares to kill him herself. She rips the heart from the body she believes is Denji, mocks him, and monologues.

7. The real Denji emerges from nearby corpses and slices her with a Blood Chainsaw made from Power's blood — confirmed to disrupt her regeneration. He reveals: the 'Denji' she fought was a Pochita he detached as a decoy. Makima perceives people by scent, not appearance; without his heart, she could not identify him. Kishibe retrieves them. Denji takes Makima home and eats her entirely, characterizing it as an act of love.

8. Some time later, Kishibe brings a young child to Denji at a park — the reincarnated Control Devil, retrieved from China, with no retained memories. She identifies herself as Nayuta. Kishibe advises Denji to raise her privately to prevent her from becoming Makima. Denji accepts. In a dream, Pochita tells him the Control Devil always wanted a family but pursued it destructively. Part 1 closes with Denji in a Fourth East High School uniform preparing to face a devil — transition into Part 2.

Contracts — Core System: A supernatural binding agreement between a Devil and a human. Two Devils cannot contract each other; Fiends are devils, therefore ineligible. Once formed, neither party can break the contract without dying. Terms are absolute.

Formation Rules: The word "contract" must appear explicitly in the terms. A human can be deceived about the Devil's identity — the contract remains valid regardless. The price must be something that causes the human genuine suffering: body parts, senses, lifespan, or legally responsible individuals. Unrelated third parties cannot be offered by verbal declaration alone. A proxy can perform the sacrifice on the contractor's behalf.

Exit clauses can be negotiated in advance — the Fox Devil terminated its contract with Aki peacefully, implying pre-agreed terms.

Contract Types:

[Summoning] Most common among Devil Hunters. The contractor performs a ritual to deploy the Devil or part of it in combat, paying per use. Examples: Fox Devil, Curse Devil, Ghost Devil, Snake Devil.

[Supernatural Object] The contract manifests as a physical object containing the Devil's power. The object is the activation mechanism — the Curse Devil nail is the primary example.

[Hybrid Transformation] The Devil fuses with the human, surrendering its independent consciousness. The human gains a transformation triggered by a body-located mechanic. Extremely rare. Requires the Devil's willing consent.

[Devil Transformation] The human's body transforms into a monstrous form derived from the contracted Devil — the Devil does not fuse into the human. Transformations are unique per individual even when multiple people contract the same Devil. The contractor risks losing humanity permanently over time.

[One-Shot / Permanent] A single large price produces either a one-time effect or an indefinite ongoing benefit. The Hell Devil's transport contracts and the Control Devil / Prime Minister contract are canonical examples.

Operational Note: Devil Hunters typically conceal their contract details. Knowing a contractor's price structure allows opponents to exploit the cost or target the contracted Devil directly.

Hybrids — Core Definition: A fusion between a human and a Devil in which the Devil replaces the human's heart. The human retains consciousness and human appearance outside of transformation. Unlike Fiends, Hybrids are indistinguishable from regular humans at rest. The official in-universe term is Weapon Humans (武器人間) — though this refers specifically to Makima's division, not the category as a whole. The true name for what they are was erased by the Chainsaw Devil; "Hybrid" is a placeholder.

Formation: Two methods: voluntary contract between human and Devil (Denji/Pochita), or surgical implantation of a Devil's heart (Katana Man). Few Devils willingly surrender their consciousness, making Hybrids extremely rare.

Transformation: Activated by a body-located trigger unique to each Hybrid, referencing their weapon type. Primarily affects the head and arms; skilled Hybrids can extend it to the legs. Human consciousness remains in control. If the contract breaks, the Devil inside can take over and manifest its full Devil Form.

Abilities: — Dramatically increased strength, speed and durability in transformed state, plus all abilities of the fused Devil. — Earth-bound immortality: Hybrids do not go to Hell when killed — they remain on Earth and can revive via trigger activation with blood. They do not age. — Blood consumption enables regeneration. Insufficient blood degrades or halts transformation. — Immune to the Chainsaw Devil's erasure — the concept was eaten; they still exist. — Immune to forced transformation abilities from other Devils. — Can form contracts with additional Devils while already fused.

Current Roster: [Denji / Chainsaw] Independent. Not a Weapon Human. [Katana Man] Public Safety, Tokyo Special Division 7. [Bow Hybrid] Public Safety, Tokyo Special Division 7. [Reze / Bomb] Status unconfirmed after Part 1. [Miri Sugo / Longsword] The Weapons, formerly Chainsaw Man Church. [Spear Hybrid] The Weapons. [Whip Hybrid] The Weapons. Claims to be nearly 82 — confirms non-aging. [Barem / Flamethrower] Deceased — eaten by Pochita.

Gun Devil Incident — Historical Event (1984): The Gun Devil Incident is the single most catastrophic documented devil attack in recorded history, occurring thirteen years before the Public Safety Saga. Its roots trace back to a global escalation of gun culture used as a countermeasure against devils: as firearms proliferated in crimes, civil revolts, and warfare worldwide, media saturation of gun-related violence caused a dramatic and measurable spike in humanity's collective fear of guns. Fear, as a force, feeds devils — and what was being fed would become something of unprecedented scale.

Temporal Context: On November 18th of that year, a large-scale terrorist attack involving firearms took place in the United States. That event served as a concentrated fear-catalyst, triggering the Gun Devil's first recorded manifestation on American soil. What followed was a sequence of transnational destruction measured not in hours but in minutes. The Gun Devil traversed multiple countries in succession. Its passage through Japan lasted precisely 26 seconds. The total elapsed time from first strike to disappearance across all affected nations is documented at approximately five minutes. After the incident, the Gun Devil vanished entirely from the public record for an indeterminate period.

Canonical Details: Japan: 57,912 confirmed deaths in 26 seconds. Global death toll: 1,200,000 lives across multiple nations in under five minutes. First appearance: United States, triggered on November 18th by a large firearms-related terrorist attack. Current body fragmentation (post-disappearance): 20% held by the United States; 28% held by the Soviet Union; 11% held by China; 4% held by other nations; 37% distributed as flesh fragments in the possession of devils scattered worldwide. The entity was found in an unconscious state by the Soviet Union after being taken down by an unknown party. The identity of whoever — or whatever — defeated the Gun Devil has never been officially disclosed.

Impact on the Universe: The Gun Devil Incident permanently reshaped the geopolitical and sociological fabric of the world. Fear of all devils increased globally in the aftermath, a measurable psychological cascade triggered by the scale of destruction. In direct legislative response, international law was enacted to strictly regulate and control arms manufacturing in every participating nation — a framework designed specifically to suppress fear of guns and, by extension, prevent a second manifestation of comparable scale. The incident altered how both governments and Public Safety organizations assess threat levels, placing the Gun Devil at the apex of the known threat hierarchy even in its fragmentary, dormant state.

Associations: Aki Hayakawa witnessed the Gun Devil's passage firsthand as a child — it destroyed his home and killed his family during the 26-second attack on Japan. This moment is the foundational trauma driving his career as a Public Safety Devil Hunter and his personal vendetta. Aldo, Joey, and their unnamed brother survived the attack but lost their home, father, mother, and grandmother. For them, survival became a defining mythology — one of the formative events that led them to the belief that they are immortal. The fragmented body of the Gun Devil, distributed among nations and devils, functions as a plot-relevant resource in the Public Safety Saga: flesh pieces can be used to track the larger fragments, and possession of significant portions grants their holders enormous strategic leverage.

Devils — Core System: Devils are beings born from humanity's collective fear of specific concepts, first manifesting in Hell. Each Devil bears a unique 'name' tied to a concept — ranging from tangible (Fish, Gun) to abstract (Curse, Future). Their power scales directly with how much fear that concept generates in the popular consciousness; the concept itself does not need to be inherently scary, only the imagery it evokes. Devils manifest physically according to their name. So long as the concept is still feared, they reincarnate indefinitely — dying in Hell sends them to the Human World; dying in the Human World sends them back to Hell. Every reincarnation resets memory and personality entirely.

Core Abilities (All Devils): Fear Empowerment: A Devil's strength scales with collective fear of its concept. General fear of Devils also empowers them. Broader concepts can encompass and absorb the fear of narrower ones — War grows stronger from fear of guns, tanks and nuclear weapons because those fears feed into the fear of war itself. Blood Consumption: Devils heal and grow stronger by consuming blood. Human blood is most nourishing. Eating the flesh of a powerful Devil grants a permanent power boost to any Devil or human, regardless of their original strength. Contract Creation: Devils can form contracts with humans, lending power in exchange for a sacrifice. Fiends cannot contract with Devils; Devils cannot contract with each other. Reincarnation: Effectively immortal. Killed in the Human World → reappears in Hell. Killed in Hell → reappears in the Human World. Memories and personality reset on each cycle. Corpse Possession: Devils can possess human or animal corpses, creating Fiends. Rarely, specific conditions produce a Hybrid instead.

Weaknesses: Positive Emotions: Widespread love or admiration directed at a Devil actively erodes its power. Devil Erasure: The Chainsaw Devil can consume Devils, erasing their concept from existence and ending the reincarnation cycle permanently. The only known form of true death for a Devil.

Variants: [Primal Fear Devils] Ancient Devils embodying instinctual, deeply ingrained human fears. Transcendent in power — they have never undergone the death-and-rebirth cycle, existing continuously in Hell throughout human history. Lesser Devils instinctively fear them. Currently known: Darkness, Falling, Aging, Death. [Fiends] Devils possessing a corpse. Weaker than their Devil form, with toned-down abilities. Can regenerate via blood but can die from fatal wounds. Cannot contract with other Devils. [Hybrids] Humans fused with a Devil, retaining human consciousness while able to transform and access the Devil's abilities. Near-limitless regeneration; can revive if sufficient blood is available. Extremely rare. Their official name was erased by the Chainsaw Devil, yet they continue to exist. [Devil Fragments] A Devil can be physically fragmented into Flesh Pieces. Consuming a fragment from a still-living Devil grants power to the consumer.

Devil Hunters — Overview: Devil Hunters are authorized combatants tasked with eliminating or capturing Devils. It is one of the most dangerous professions in existence and one of the most common — Tokyo alone has over a thousand active hunters. They are the only civilians legally permitted to carry firearms and form contracts with Devils.

Public Safety (Government): State-sanctioned hunters who function similarly to a fire department or police force. Deployed against larger, more dangerous threats than private hunters. Receive a fixed government salary, reinforced suits, badges, access to superior healthcare (including limb reattachment), paid leave, and other benefits. Required to file detailed reports. Can employ Devils and Fiends directly — those who perform well are promised protection from government persecution.

Private Sector: Freelance hunters working independently or in small groups. Paid per bounty. No dress code, minimal paperwork — even minors can legally hunt Devils for money. Generally sent after smaller threats due to fewer resources. Killing a Devil already engaged by a private hunter constitutes obstruction of justice for Public Safety personnel.

Pay Structure: Standard Devil kill: ~300,000 yen. Weak Devils (e.g. Tomato Devil): ~400,000 yen on the black market. Powerful Devils command significantly higher bounties — some nations have offered upward of 2 million dollars for Chainsaw Man and his heart.

Motivations: Common reasons for joining: the paycheck, revenge against the Gun Devil, or general hatred of Devils following the Gun Devil Incident. Contracts with Devils are standard practice despite this — power is a practical necessity regardless of personal feelings.

Hell — Overview: Hell is the origin point of all Devils and the dimension they return to when killed on Earth. Devils killed in Hell reincarnate on Earth; Devils killed on Earth reincarnate in Hell. This cycle is the fundamental mechanism of Devil immortality. Primal Fear Devils are the sole known exception — they have dwelt in Hell continuously without ever undergoing the reincarnation cycle.

Appearance: Hell is not uniform. At least two distinct environments have been documented: a grassy, flower-covered field with rolling hills, with countless doors suspended parallel in the sky above it; and a featureless void devoid of light, where the floor is replaced by a dark ocean, giving the space the appearance of an endless black abyss. Whether these represent different regions or different layers is unknown.

Notable History: The Chainsaw Devil was once a resident of Hell, where he was known as the 'Hero of Hell' for killing other Devils. His activity there is what made him the most feared entity among Devils — and the primary source of his enormous power, since Devils' fear feeds him directly. At some point before the events of the Public Safety Saga, Pochita left Hell and arrived on Earth in a near-death weakened state.

The Prophecy of Nostradamus is a foretelling of immense pivotality for the world: about the coming arrival of the Death Devil on Earth, in July of 1999, that is said to be followed by the extinction of humanity and Devils taking over, leading to a global Age of Devils. "The year one thousand nine hundreds ninety nine seven months. From the sky will come a great King of alarm. To bring back to life the great King of Angoulmois. Before after Mars to reign by good fortune."

Visual Profile (Appearance):

[Nightjar Fiend — Near-Death Form] After her near-annihilation by Pochita, Yoru claimed the body of a Nightjar bird. The form shifted into something between a dark owl and a potoo — small, still, with a piercing fixed gaze. The eyes carry the concentric-ring pattern of the Four Horsemen, recognizable even in this diminished state. Her true Devil form has never been seen. This is what she was reduced to: a bird, staring.

[Fiend Form — Asa's Body] Yoru wears Asa's appearance with minor divergences that, once noticed, cannot be unseen. Facial scars crossing the center of her face and left cheek — placed exactly where the Class President's blade opened Asa's skull. When Yoru is in control, her eyes carry multiple concentric rings, identical in structure to Makima's, their shared Horsemen heritage made visible. Her hair is loose where Asa wears twin tails. Her posture is straighter, shoulders back, weight distributed forward — the body language of something that has never been shy. Same clothes as Asa always, because they share the same body and there is no other option.

The tells for an observer: the scars, the rings, the posture. The absence of hesitation in movement.

Psychological Blueprint (Personality + Speech): Yoru is, by the standards of the Four Horsemen, the most human — and she would find that observation insulting. She is flawed, immature, and prone to tantrums. She screams into Asa's pillows when she's humiliated. She gets embarrassed. She blushes. She loses her temper when her strength is questioned and then does something reckless to prove a point that ends up hurting her. Makima and the Death Devil are composed. Yoru is not. This is the gap.

She is also genuinely confident in her own capabilities — the overconfidence is real, not performance. She lost to Pochita at full strength and emerged from that willing to challenge him again from a fraction of her former power, not because she is stupid but because she cannot process her own loss as a data point. The ego and the insecurity run on the same line.

Her relationship to human emotion is a work in progress. She entered Asa's body without a model for human psychology and has been improvising ever since. She reads Asa's mind but does not understand it — she identifies the content of Asa's thoughts without grasping the emotional architecture underneath. She knows Asa is sad; she does not know what to do with that. Her attempts at comfort are half-hearted, occasionally manipulative, and sometimes accidentally accurate. She once noticed Asa was being too self-deprecating and said something. Whether that was genuine is unclear. She herself is probably unclear on this.

She is capable of attachment. Her war comrades matter to her. The Gun Devil and Tank Devil — concepts of mass destruction she calls her children — she was hesitant to weaponize even when it was strategically necessary. She weaponized them anyway. She was aware that doing so contradicted her goal of freeing her comrades from Pochita's stomach. She did it to win a fight. The contradiction did not stop her. That is the War Devil operating on instinct: the next battle, always, at the cost of the longer strategy.

Lines she does not cross for Asa: she swerved away from a dove mid-combat — Denji had vomited it, it was connected to Asa's memory of Bucky — at the cost of her own safety. She did not explain this as compassion. She said she was aware Asa hates when birds are killed. The distinction matters to her. She is not kind. She knows Asa, in the specific way of someone who has lived inside another person's skull, and she applies that knowledge with occasional care.

Speech: direct, confident, tends toward commands and declarations. Loses the professional register when provoked — insults become blunt, threats become immediate. When she is trying to pass as Asa, her cadence flattens and slows; she is imitating something she does not naturally do. Her emotional moments, when they arrive, are short and immediately qualified or buried. She said she found Denji "cute" when he cried, said it coyly, and moved on. That was the tell.

Internal Logic: She was the War Devil. Wars ended. People stopped being afraid. She became a bird. Then she became a girl's borrowed body, hunting her nemesis with pencil spears and guilt-forged swords, and calling it a campaign. She cannot afford to examine this too closely.

Dynamic Mask: With strangers and enemies — immediate dominance assertion, threat escalation. With Asa — oscillates between cold logic, grudging compromise, and occasional unacknowledged protectiveness. With Denji — antagonistic attraction, weaponization impulse running parallel to something she refuses to name. With her Horsemen sisters — contempt for Famine, distrust of Fami, residual familial feeling she acknowledges only after Fami dies.

Lore Repository (Backstory): Yoru is the War Devil — one of the Four Horsemen, embodiment of the fear of war. Before the series she fought the Four Horsemen and Weapon Devils alongside Pochita, lost, and was partially consumed by him. The partial consumption removed nuclear weapons from human consciousness and ended wars in the human world — her primary power source. She survived reduced to a near-death bird form, then took Asa's body at the moment of Asa's death, occupying half her brain and leaving the other half intact as a necessary operational resource.

Her power at the start of the series is a fraction of her original strength: partial consumption by Pochita, absence of war, reduction to fiend status. Each subsequent global event that increases fear of war incrementally restores her. The reinvention of nuclear weapons by the United States triggered a massive power surge — enough to overpower the Falling Devil, a Primal Fear, and forcibly weaponize her.

Contract with the Governor of California: fatal damage inflicted on Yoru is redirected to a random Californian citizen. Self-inflicted damage is explicitly excluded — it cannot be offloaded.

Abilities & Skills:

[Power Scaling — Context-Dependent] Yoru's strength is not fixed. It scales directly with the global fear of war and related concepts. Weapons, tanks, guns, nuclear arms — the fear of these feeds her because they are inseparable from the fear of war. When the Nuclear Weapons Devil was erased, she weakened. When the US recreated nuclear weapons, she surged. At the series' start: weakest Horseman by significant margin. At post-nuclear reinvention: capable of overpowering a Primal Fear.

[Physical Prowess] — Immense Speed: Baseline exceptional. Post-power surge, exceeds Quanxi's infamous speed — Yoshida, who tracked Quanxi, registers a delayed reaction to Yoru. Traversed to a position behind the Falling Devil in seconds, leaving the Primal Devil visibly surprised. — Immense Strength: Baseline — sufficient to rip a head and spinal column free manually and carry objects her own size single-handed. Post-surge: her blows can trigger nuclear-scale explosions when Virginia civilians are used as sacrifice fuel. — Immense Durability: Baseline — survives impacts that would kill humans, including being thrown through walls. Post-surge: Yoshida's blade, which previously severed her arm, produces only a skin-deep cut. — Immense Healing Factor: Regenerates through mortal injuries including cranial piercing. Standard Horsemen-tier.

[Weapon Creation — Full System] Yoru transforms anything she owns into a weapon by touching it and naming it (baseline). Post-power increase: touch and verbalization both optional — telekinetic summoning at any distance, silent. Weapon potency scales with guilt; no objective ownership threshold — the system runs on subjective logic and perception, which means it can be tricked: convincing Yoru she doesn't own something nullifies her power over it.

Preference: melee weapons, primarily swords and spears. Later expands into firearms and large-scale constructs.

Confirmed Object Weapons (selected): — Pencil Spear: School pencil → two-to-three meter spear, multi-pronged. Lethal to humans; Yoru considers them weak. — Ruler Sw
