When Denji was young his mother passed away from unknown heart illness, while his father accumulated a large debt of 38 million yen to the Yakuza and became a violent alcoholic who frequently abused his son. Eventually, Denji's father attacked his son so viscously the young boy was forced to kill him in self defense, this event was so traumatic, Denji repressed the memory of what he did. The Yakuza then forces Denji to pay off the debt in his father place threatening to murder him if he doesn't meet his pay quotas. As Denji is mourning his father's death at his grave he finds Pochita aka ethe original Chainsaw Devil. However Pochita is heavily injured thus Denji offers to heal him with his blood on the condition they form a contract so he can use Pochita to pay off his debt. Over the years the two bond together as friends as the young-boy also convinced his boss to keep Pochita since the dog might be a valuable asset in finding money.

Public Safety Saga

Intro arc

Deni and Pochita being killed.

Years later a now sixteen year old Denji becomes a private devil hunter killing devils for a quick buck to pay off his debt like taking down a Tomato devil for the Debt Collector. He also chops down trees and sells his own body parts like his eye and one of his testicles. However despite his efforts the debt collector pays him a miniscule amount for his services which is barley enough to cover food, water and rent so all Denji can afford for dinner is a measly slice of bread. A member of the Yakuza then drives up and offers Denji 100 yen to eat a cigarette to which he immediately accepts desperate for money but spits it out as soon as the Yakuza leaves. Denji then goes back to his house to eat the bread he bought with Pochita. Denji then laments that he probably won't be able to pay off debt before he dies and voices his dream to get a girlfriend, and eat jam with bread. However suddenly Denji coughs up blood just as his mother did causing him and Pochita much concern. Suddenly the Debt Collector knocks on his door and gives him a new devil hunting job. He drives Pochita and Denji to a abandoned warehouse and although the Debt Collector is grateful for Denji's loyalty but nonetheless betrays and stabs him in the chest. The old man explains that they made a contract with the Zombie Devil in exchange for it lending them its powers, and it was a foolish decision since the Zombie Devil cannot grant them anything except turning them into mindless zombies. Denji and Pochita were then shredded by the minions of the Zombie Devil, and killed, with their remains being thrown into a dumpster. Denji then hallucinates Pochita and wonder if he took over his body just like her offered. However, Pochita has a better idea he claims that he will resurrect Denji by becoming his heart and in exchange all he asks is that Denji continue to follow his dreams.

Denji transforms into Chainsaw Man for the first time.

Denji then emerges from the dumpster anew with a chainsaw starter cord on his chest now a devil-human hybrid much to the Zombie Devil's shock. Denji questions them on the Yakuza on futility of even making a contract with the Zombie Devil when they have all the power they wanted. Denji then decides that if they are going to get in the way of achieving his and Pochita's dreams then they needed to die. Denji then pulls the starter cord on his chest and transforms into a devil with chainsaws protruding out of his arms and head and attacks his assailants. Denji cheerfully notes with the Yakuza gone, he won't have anybody to pay debts to, thus freeing himself from them. After eliminating the Yakuza zombies, Denji slices up the Zombie Devil and his minions.

This causes Denji to revert back to his human form. Although one of the agents assumes him to be a fiend the girl does not believe this to be the case. She then tells Denji that she is a devil hunter from public safety and since her job is to kill devils she is inclined to slay Denji now that he is one. However she offers to spare him in exchange for becoming her "pet" and even offers him good food like bread with jam. Denji seduced by the woman's charms easily accepts. The two then get into a car and Denji starts to get hungry. The woman then offers to buy him food and they stop at a restaurant.

However this was a ruse and it's revealed the Muscle Devil took over the girls body and intends to kill Denji for interfering. However, Denji manages to defeat the devil and rescue the girl. Back at the restaurant Denji passes out from the blood loss he sustains while in his chainsaw form. When he wakes up the woman gives him udon as if he were a dog eating treats.

Aki and Denji go on a patrol only for former to be irritated at Denji's supposed lax nature, lack of seriousness and his crush on Makima. Aki then beats Denji up in an alley and tells him that with his ridiculous goals and aspirations he is not worthy of being a devil hunter and tells him to just leave. However Denji runs up and kicks Aki in the balls telling him that his reason for being a devil hunter as well as his dreams are just as important as anyone else. The two get into a fight where Denji kicks Aki in the balls so many times he collapses from his injuries.

Aki questions why he didn't just transform and kill it to which Denji explains that going into his chainsaw form hurts him and he wanted the fiend to die quick and painless. Aki gets angered by this and tells Denji that a devil killed his family and if he sees an opportunity to make one suffer he would take it. As Aki leaves Denji privately admits he just didn't want to get blood all over the porn magazines the fiend had.

As she puts on an apron, she sees Denji is already waiting for her at a table. The girl sits next to him, ordering a pair of coffees for the two of them, which Denji drinks with a disgusted grimace. She laughs and flirtatiously touches his shoulder, as a flustered Denji wonders whether she likes him. The girl introduces herself as Reze, and Denji responds with his name. Denji worriedly thinks of Makima, as he realizes that his feelings for Reze are growing.

Denji ends up becoming so enamored with Reze he goes to her diner everyday for a full week just to see her. Denji then notices Reze studying and the two have a discussion about school. Reze trys to teach Denji to read but he ends up comically writing the word "Balls" because it's the only word he knows how to spell.

Reze then offers Denji to go swimming in the school's pool. Reze then suggests they go skinny dipping since there is no one else there but the two of them. Denji is reluctant to do so but he decides to anyway. He then takes a cannonball in the pool. Reze then decides to teach Denji how to swim. However it soon begins raining and the two head inside. Reze then poses Denji a philosophical question; which would he rather be the Town Mouse or the City Mouse. Denji chooses the City Mouse as he would want to be surrounded by commodities even if there is more present danger in the city. Reze the offers to take denji to a local festival to which Denji accepts as long as it's after work. Denji then compliments on how cute Reze is. Denji then realizes when he closes his eyes he see's both Makima and Reze, meaning he has feelings for the both of them.

The next day the two go to the festival and play games, eat treats and look at goldfish. Reze and Denji then go to a high peak to have a good veiw of the fireworks. Reze then tells Denji that she has been thinking. His life is terrible and thus she offers to run away with him. Although Denji likes Reze he is hesitant to accept he is doing well in his job and with his friends. Reze then surmises that he likes someone else. Suddenly Reze then kisses Denji as the fireworks go off. However the kiss soon turns into a nightmare as it's revealed that Reze bit off Denji's tounge. It's then that it's revealed that much like Katana Man, Reze was contracted to steal Denji's heart for the Gun Devil.

Denji then comes to the startling realization that every woman he meets tries to murder him. He then becomes angered and laments that everyone wants his Chainsaw heart but not one girl wants his own heart. Reze however tries to argue that she truly did love Denji. Denji however points out that he is happy with Makima, Reze however points out that she is a witch and Denji is merely her pet. Denji then vows to stop Reze from killing more people. As they fight Denji is on the losing end. Reze points out that he needs to understand his powers more and apply himself. Ultimately no matter what Denji does he keeps getting pushed back.

He explains that in spite of his wonderful life he would feel guilty about her get arrested by Public Safety. However, Reze claims that her feeling were entirely fabricated to gain his trust and that she lied about liking him earlier. Despite this, Denji asks Reze to runaway with him, pointing out that if her feeling were fake why did she teach him how to swim. Reze responds by breaking Denji's neck and telling his to wise up a little. Denji tells Reze he will be waiting at the cafe at noon.

Denji notices Power’s change in behavior and Aki missing an arm, showing concern for both of his comrades. Makima later invites Denji to go on a trip with just the two of them, but he turns her down to help Power.

During this time, Denji bonds more with Aki and Power, while concluding that there are some things he is better off not knowing, dismissing the mysterious door in his dreams. As Power slowly begins to recover from her traumatic experience, the Hayakawa family take a trip to Hokkaido to pay respects for Aki’s deceased parents and brother. During that time, Denji and Power’s crazy antics manage to cheer Aki up as the three grow closer than before.

Back in Tokyo, the trio learn the truth about the Gun Devil from Makima, who reveals that the Devil was already defeated and confined between various countries. Denji and the others are shocked over this but the former still resolves to join Makima’s mission to fully destroy the Gun Devil. Outside, Aki realizes that even after they killed the Gun Devil, the body would merely be collected by the Japanese government, continuing the cycle of global hostilities whilst also meaning the Gun Devil can never truly die. Denji expresses confusion, believing that the Gun Devil must be mortal, or else Makima would not have promised him a wish in return for killing it.

Later at night, Aki learns from the Future Devil that in the distant future, he and Power will be killed by Denji, and that Pochita will make his return in the following time. Denji remains at Aki’s apartment with Power and Meowy while Aki and Angel visit Makima at a beach. Makima then takes full control of Aki and Angel, and battles 20% of the Gun Devil sent by the U.S. using various Devil contracts and powers.

Makima manages to defeat the Gun Devil and forces it to inhabit Aki’s body. She sends Aki back to his apartment to kill Denji and Power. After the attack ends, Denji receives a phone call from Makima that the Gun Devil has inhabited a corpse and is waiting outside the door. Hearing the sound of knocking, Denji checks on it, only to discover Aki, now transformed into the Gun Fiend. The Gun Fiend then begins attacking Denji and Power, destroying their apartment in the process.

Throughout their battle, Denji desperately begs Aki to snap out of it and tries to bring him back to his senses. Aki, however, visions his battle against Denji as a playful snowball fight, not realizing what really happened to him. However, none of Denji’s efforts work with Aki continuing to wreak havoc and chaos as he continues destroying the neighborhood around him.

Eventually, on the behalf of various civilians, Denji is left with no choice but to stop him. Denji manages to finish off Aki by impaling him with both of his chainsaws. Left broken and traumatized even further, Denji slumps down as he silently mourns over the loss of Aki Hayakawa.

Control Devil arc

Denji and Power are left alone with half of Aki’s money in a new apartment, spending it on food to cope with Aki’s demise. One night, Denji goes out on a walk but is unable to fully process the fact that he killed Aki as he vomits. Makima approaches him and decides to take him to her apartment. From there, Denji spends time with Makima and her seven dogs in an attempt to move on from Aki’s death.

However, Denji also wants to be treated like a dog when Makima reminds him that she owes him for killing the Gun Devil. Makima reveals that she invited Power earlier and tells Denji that she plans on killing her once he opens the front door. Denji complies with Makima’s orders despite Pochita’s voice telling him not to open the door. Upon doing so, Denji sees a terrified Power holding a birthday cake for his seventeenth birthday. Before either have the time to react, Power is immediately killed by Makima obliterating her entire body.

Denji freezes in shock, unable to speak as Makima closes the door. Still shaken, Denji wonders if this is a dream, to which Makima begins laughing hysterically as she starts to show her true colors as the Control Devil. It is then revealed that Makima had deliberately planned to provide him with a family unit and various sources of happiness, only to rip them away in order to break him. She also had looked into his past, discovering that Denji had repressed the truth that he killed his father.

By unlocking the truth, Makima gaslights Denji into believing he doesn’t deserve to be happy after causing the deaths of Aki and Power. This causes Denji to completely shut down as he enters a catatonic state. In addition, this ultimately breaks his contract with Pochita, allowing Makima to gain access to the Chainsaw Devil and his ability. The next day, Makima takes the despondent Denji with her in preparation for Pochita’s return.

Out of nowhere, Kishibe and his team launch a full-scale attack on Makima, refusing to let her accomplish her plans of conquering the world. Makima manages to bring out Pochita, who now reappears in his original form through taking control of Denji’s body. However, Pochita wants nothing to do with Makima’s plans and instead focuses on trying to bring Denji back to life. When Pochita is incapacitated by Makima, Power emerges from the Chainsaw Devil’s body thanks to Denji’s earlier action of drinking her blood. Despite being overwhelmed, Power’s memories of her bond with Denji causes her to resist Makima’s control. She escapes with Pochita to a nearby dumpster, allowing Denji to be revived much to Power’s relief.

Denji tells Power he doesn’t have the will to live anymore, to which Power rebuffs that claim. During her final moments before vanishing, Power makes him form a contract to find her again in Hell. With Power gone, Denji grieves over the loss of his new family, only to be approached by Kishibe. Kishibe questions if Denji is still himself and offers to help him escape from Makima. Denji shows Kishibe that he is still himself by tearfully throwing a peace sign back at him.

Hiding away with Kishibe and Kobeni, Denji admits that although he is physically fine, he is an emotional wreck, and is coming to terms with the fact he'd lived his entire life in subservience to others, never making any significant choices of his own. Kobeni makes Denji realize that a life filled with hardships and struggles is indeed normal just as he sees a broadcast of people celebrating over his actions as Chainsaw Man.

Seeing all the praise and love from so many people, Denji regains the will to live and resolves to still be Chainsaw Man out of a selfish desire to chase his dreams. He then plots with Kishibe on how to handle Makima and her army. Denji temporarily separates Pochita from himself as part of his plan to ambush Makima at the right time. Donning a Public Safety uniform and a chainsaw made of Power’s blood, Denji heads out to confront Makima for the final time at a graveyard. While Pochita goes all out against Makima and her brainwashed Hybrids, Denji blends in with the other brainwashed servants. Sometime afterward, Denji sneaks up behind Makima, who is resting during the aftermath of her battle with Pochita.

He then swiftly uses the blood-themed chainsaw to strike Makima down the chest. Makima begins to bleed, unable to recover as Denji explains how he was able to outsmart her using Pochita as a decoy. Kishibe pulls up behind Denji with a van, and Denji apologizes as he shreds Makima to pieces, collecting her remains in separate boxes. Arriving back at his apartment, Denji tells Kishibe that he is prepared to enact his final act to defeat Makima for good.

Once Kishibe leaves, Denji begins to cannibalize Makima’s remains until she is completely consumed. During that time, despite everything Makima had done to him, Denji realizes that he still likes her. After Makima’s demise, Denji meets with Kishibe and explains how he managed to kill off Makima for good. He also discovers that Makima had reincarnated into Nayuta, who is placed under his care by Kishibe. Once that is done, Kishibe leaves Denji with Nayuta.

Denji decides to adopt Nayuta and the two head home with their dogs and Meowy. Later that night, Denji has a dream with Pochita, who tells him to grant the Control Devil's dream by forming an equal relationship with her as a family. He then leaves Public Safety and starts attending high school while continuing to be Chainsaw Man. Denji also continues raising Nayuta following this point while trying to reveal his identity over time.

He continues to purge devils from his body—next is the Bitterness Devil, which prompts him to dive into a lake to clear his head. Underwater, he recalls memories of Reze, Nayuta, and his old pets. A vision of Pochita swims to him, and Denji realizes Pochita consumed devils to preserve Denji’s happy memories. Asa pulls him out of the water, and he regains his will to live. Realizing the devil head he vomited didn’t come from his own body, Denji concludes he’s linked to Pochita’s body in the real world. Determined, he devises a plan: starve himself until he can eat and refuel Pochita. With an axe forged from the Bitterness Devil’s tooth, Denji hacks open a tree-shaped human, drinks its blood, and pulls his cord to revive Pochita.

Denji keeps feeding and activating Pochita like a perpetual engine. After freeing him, Denji instructs him to vomit useful devils. Unexpectedly, Denji pukes up Yoshida. Shocked but adapting quickly, Yoshida proposes a temporary alliance. Denji reluctantly agrees, letting Yoshida and Yoru channel their powers through his body. With help from the Octopus Devil and Fumiko, they drag the Aging Devil back into its realm. Yoshida offers it a deal: send everyone back. Denji adds that since only he can stay behind, they’d be stuck with him forever. With no other choice, the Aging Devil agrees. Back in the real world, Denji and the others eat at a café, ignoring the chaos of the ongoing Pseudo-Chainsaw conflict.

Current Arc

In June, while eating, Denji recalls how "Asa" defeated Pochita by flattening Tokyo with the Statue of Liberty. When Denji notes something strange about her, Yoru reveals herself as the War Devil. Denji is stunned as Yoru gleefully recounts the deaths she caused using Asa’s body. Denji then awkwardly asks if it was Asa or Yoru who gave him the handjob.

Yoshida changes the topic, reminding them that the Death Devil is nearing and urges Yoru to weaponize Denji. Denji tries to shoot him but finds the gun unloaded. Yoru mocks humanity while wasting their dessert and dragging Denji outside to "have fun." She yanks his cord and forces his transformation.

Instead of carnage, Denji takes her to eat potstickers on a rooftop. When Denji asks about the Fire Devil, Yoru says he’ll appear once the Death Devil arrives, and the Control Devil might return—though not as the same person. Denji, remembering his promise to Power, tells Yoru she’s one of the few friends he has left. As he expresses joy, Yoru teasingly sits between his legs, prompting Denji to ask if she hates him.

To his surprise, Yoru admits both she and Asa like him romantically. Overwhelmed, Denji tears up. Yoru kisses him again and offers a deal: defeat the Death Devil, and they can have sex. If he fails, she’ll turn him into a weapon. Cautious of Yoru and unable to sleep, Denji cooks for them. After eating, Asa regains control to speak with Denji.

She points a finger gun at him and then her own head, Asa breaks down, admitting she wants to die to stop Yoru from committing an unknown atrocity but is too afraid. She begs Denji to kill her, saying Yoru’s plan to kill the Death Devil is too horrific to describe—worse than extinction.

Denji confused and nervous, attacks her with a chair in response, which she dodges. She accuses him of being a murderer, but he reminds her she asked him to do it. Asa breaks down in tears, overwhelmed by guilt and helplessness. Denji tells her that while he’s died many times, he’s never gotten used to it—and that she clearly doesn’t really want to die either. He promises to take on the Death Devil first, then deal with the aftermath.

Later, Asa and Denji briefly speak on the current situation where she decides to not think about negatives and lets Yoru regain control. The two rampage through ruined Tokyo on a stolen bike, killing Pseudo-Chainsaw People. However their fun is interrupted when the Fake Chainsaw Man blocks their path and causes them to crash. While criticizing Denji for not acting like a "Solitary Warrior from Hell" and approaching him with murderous intent, he responds that Fake Chainsaw Man got his backstory wrong, dodging his initial strikes and cutting off one of his arms.

After cryptically threatening Denji, the Falling Devil returns and manipulates gravity, causing civilians to fall sideways. Denji saves a woman, but the Fake Chainsaw Man criticizes him again for only helping women. Denji asks for help from Yoru, but she blasts off the woman’s hand for fun, revealing her cruelty. Denji, angered and disgusted, prepares to fight her, but Yoru surprises him by shooting the imposter instead, creating an opening. Denji cuts off the doppelgänger’s arm.

Fake Chainsaw Man accuses them of faking their argument to distract him. Denji however denies this and explains that Yoru is plain crazy. Before they can finish him, Pseudo-Chainsaw People shield the fake, fusing with him to regenerate his limbs. When the civilians revert to their human forms, one expresses relief at being saved by the "real" Chainsaw Man. But the fake brutally injures them, enraging Denji.

Denji struggles to counter without hurting civilians. One suggests targeting the heart. Denji sees the ripcord but hesitates when the imposter uses a civilian as a shield. This gives the fake a chance to punch Denji into a six story building. Yoru arrives and tells him he won’t win by sparing the civilians lives, though Denji argues that if he kills them, he'll have fewer fans and less to no people left that will like him. Yoru reminds him that even if he saves people, he’ll be forgotten, just like Asa was prior and then asks if she can help him kill Fake Chainsaw Man. Before Denji can make a decision, the Falling Devil lifts the building they are in to drop it on nearby civilians along with the Famine Devil.

However Yoru makes the building her property and transforms it into a sword as Denji catches her in the middle of a free fall. Yoru then leaves to fight the Falling Devil, while Denji is left to deal with the Fake Chainsaw Man that approaches him near a cross walk. Denji reluctant to harm innocent people, makes a plea to that he will spare the fake's live that if he sets the civilians in his body free. Fake Chainsaw man ignores Denji and lunges at him, which springs Denji into action as he proceeded to decapitate the fake. The fakes body makes one final attempt to strike Denji, so he vertically bisects his body, killing the fake and setting most of the civilians free at the cost of some casualties. Following Fake Chainsaw Man's death, the Fire Devil emerges from the corpse complimenting Denji's strength. Denji questioned if the Fire Devil would fight him next but they deny this and instead asks Denji if he remembers Fake Chainsaw Man's human face. Denji admits he does not so the Fire Devil goes on to explain that the man was a student at Denji's school that alongside his younger twin brother idolized, and that the pair saved them while it was mortally injured. Fire Devil further explains that it granted contracts with the twins and others that shared their vision of justice and was proud seeing the twins use their powers to save others.

However, They point out to Denji that on the day he fought the Cockroach Devil a year ago, and chose to save a cat instead of the lives of the elderly and a young man, that the young man who died was Fake Chainsaws twin. Realizing what this means, Denji stares at the decapitated in head in silence as the Fire Devil continues to criticize him for his betrayal and disregard for Fake Chainsaws twins and for the fact he cant even remember the faces. Denji asks if the Fire Devil wants him to apologize but they flatly deny it, and instead reveal they are going to make Denji choose between two options and urges him to not make the same mistake again.

Confused, Denji asks what mistake as building collapses behind him, he then spots Yoru trapped beneath the rubble. While claiming she hasn't lost yet, she asks and pleads to Denji to save her and responds accordingly while the Falling Devil confronts him. Not remembering the Falling Devil, Yoru angrily reminds him shes a devil and to save her first before fighting such a powerful devil. Falling Devil shockingly agrees with Yoru and opts to let Denji save her, explaining she is merely here to follow Death Devil's orders by plunging humanity into an abyss of terror. As she summons more buildings to drop on civilians Denji attempts to stop her, though he is caught in her gravitational guilt ability. With his Chainsaw's retracted, Falling notes that Denji hasn't changed at all since their last encounter and that his chainsaws are ineffective against her.

Denji is then shown an apparition of Fake Chainsaw Man in his human form, telling him that he should be all too aware of how it feels to lose a loved one. He continues angrily shaming Denji for being the cause of his brothers death as he splits apart and combusts into flames, causing a frightened Denji to apologize. In the real world his body floats upwards as he continues apologizing, though Asa manages to regain control of her body and rushes to grab hold of him.
