As a horror writer, I’ve always been drawn not only to fear, but to the deeply unsettling. Some manga go beyond simple scares or gore and tap into something more visceral, whether it’s psychological torment, abusive relationships, or raw emotional breakdown.
This list is dedicated to these works: the most disturbing manga I’ve ever read.

Disturbing manga don’t rely on jump scares or monsters. Instead, they unnerve you through cruelty, obsession, moral collapse, and surreal horror. They feature everything from graphical violence and exploitation to mental illness, family trauma, and stories that spiral into pure madness.
What ties them together isn’t just shock value, it’s the discomfort they leave behind. These are stories that stick with you long after the final page.
Whether it’s body horror, psychological manipulation or just pure emotional dread, every manga on this list has something that got under my skin.
Mild spoiler warning: I keep things vague, but sometimes details are hard to avoid.
Here’s my curated list of the most disturbing manga I’ve ever read (last updated: July 2025).
22. BIBLIOMANIA

BIBLIOMANIA is a disturbing, surreal decent into body horror and madness. It’s an experimental manga where visual beauty and grotesque transformations collide in nightmarish ways.
The story follows Alice, a young girl with a childlike appearance who wakes up in Room 431 of an otherworldly mansion. A talking serpent warns her not to leave the room or her body will rot. Still, she steps outside, ignoring the consequences. Each room she enters contorts her body and mind further, dragging her deeper into a fever dream that feels more like a ritual than a journey.
Alice’s whimsical design and innocent demeanor make the horror hit even harder. As her body warps and melts, as limbs twist and skin unravels, the manga forces you to confront the most intimate form of horror: the loss of your physical identity.

The mansion itself is an oppressive, surreal setting, like something from a corrupted fairy tale. It’s full of arcane symbolism, monstrous beings, and dreamlike horrors that feel less like plot devices and more like nightmares made flesh. The deeper Alice ventures, the more the story spirals into pure madness.
The art by Macchiro is stunning in the most horrifying way. Alice’s transformation is rendered with excruciating detail. It’s beautiful, but also deeply disturbing.
By the end, BIBLIOMANIA isn’t just disturbing; it’s harrowing. A short but unforgettable descent into the grotesque, and easily one of the most unsettling one-shots I ever read.

21. God’s Left Hand, Devil’s Right Hand

God’s Left Hand, Devil’s Right Hand is Kazuo Umezu’s most violent and disturbing manga. It’s a feverish collection of supernatural visions, grotesque deaths, and nightmarish storytelling.
The manga follows Sou, a boy cursed with terrifying premonitions. He sees horrific events before they happen: murders, mutilations, and even stranger incidents. He tries to stop them, but his efforts rarely succeed.
Each arc plays out like a self-contained horror story, ranging from grounded scenarios like serial killers and child murders, to surreal nightmares involving ghosts, parasitic insects, and twisted monsters. The imagery is drenched in gore, but what makes it truly disturbing is the tone. There’s the feeling that nothing is safe, and evil can emerge from the most mundane settings.

Umezu’s art is stiff and outdated by modern standards, but it adds to the unsettling atmosphere. His expressive faces, sudden tonal shifts, and graphic violence create a unique visual style that hits harder than it should. The contrast between childish protagonist and horrifying events only heightens the discomfort.
The manga can be quite divisive. Some arcs are stronger than others, but when it goes dark, it really goes dark. From the infamous Eroded Scissors arc to the Tongue of the Spider Queen, the manga dives into some of the most sadistic and unhinged imagery of Umezu’s career.
God’s Left Hand, Devil’s Right Hand is not a refined work. It’s raw, chaotic, and deeply strange, but it’s also unforgettable. It may be old-school horror, but it remains one of the most disturbing manga ever drawn.

20. Horror Mansion

Horror Mansion is a relic of the late 80s and early 90s gore manga. It’s raw, grotesque, and unapologetically disturbing. Created by Nori Ochazuke, it’s a long-running collection of short horror stories where narrative often takes a backseat to pure shock value.
The art is scratchy, uneven and extremely rough by modern standards. Yet somehow, that roughness works. The raw, unrefined linework makes the horror feel more jagged and erratic. Gore is abundant. Bodies are torn, mutilated, dismembered, and rearranged in every imaginable way.
Most of the stories follow a simple setup designed to end in carnage. Sometimes it feels like the narrative only exists to justify a few pages of violent escalation. Every so often, however, you get a standout: Ball of Flesh, in which a girl discovers her father’s horrifying secret, or Memory Troubles, a surreal tale of altered memories. These rare entries add genuine psychological unease to the visual grotesquery.

Later chapters try to connect a few storylines, but the overarching narrative never becomes a compelling thread. Horror Mansion works best as pure horror schlock: loud, violent, inconsistent, and often disturbing.
This isn’t a refined or elegant manga. But if you crave relentless gore, taboo-smashing horror and some of the most unsettling body horror from the old-school era, Horror Mansion delivers.

19. Fire Punch

Fire Punch is one of the most miserable manga ever written. Disturbing in premise, brutal in execution, and utterly unpredictable, it’s a work of cruelty, nihilism and existential weirdness, written by Tatsuki Fujimoto.
The story begins with Agni, a ‘Blessed’ orphan with regenerative powers, who’s burned alive by an unextinguishable flame. Yet he doesn’t die. His body keeps healing endlessly, and he remains in constant agonizing pain for years. When he finally adapts, he sets off across a frozen hellscape, still wreathed in fire to seek revenge.
That alone would be disturbing enough, but Fire Punch is only getting started.
This manga is full of horrifying imagery: cannibalism, sexual violence, dismemberment, suicide, cults, and mass slaughter. It’s not just gory, it’s emotionally corrosive. Every new development strips more humanity away.

Then, partway through, Fire Punch changes. We meet Togata, a deranged cinephile who decides to make a movie out of Agni’s life. Suddenly the manga becomes meta, self-aware, even absurd. It parodies hero tropes, breaks character arcs, and mocks its own existence. Only to then lurch back into another spiral of misery and despair.
The result is a story that’s chaotic, genre-bending, and deeply disturbing. Fujimoto leans into misery, not just for horror, but to question the meaning of the narrative itself. Does suffering create depth? Is revenge real?
By the end, Fire Punch becomes something else entirely. Whether it’s brilliant or just edgy is debatable, but one thing is certain: it leaves a mark.
If you want a manga that’s cruel, deranged, and disturbingly unforgettable, Fire Punch is where it’s at.

18. Keep on Vibrating

Keep on Vibrating by Jiro Matsumoto is the most explicit adult manga on this list, and arguably the most unhinged.
It’s a collection of one-shots drenched in sex, violence, and surreal madness. Some chapters are loosely connected, others are completely standalone, but they all share the same disorienting, fever-dream logic and unapologetically graphical content.
The opening story alone is one of the most bizarre and disturbing things I’ve ever read. It features full-frontal sex, casual violence, and a plot that barely tries to make sense. And yet, there’s a strange rhythm to the chaos. Mundane dialogue unfolds over horrific backdrops. Emotions are detached, characters act with dreamlike absurdity, and reality bends at will.
The artwork is messy, gritty, and raw, perfectly matching the bleak tone. It’s not conventionally ‘good,’ but it’s effective. You can feel the dirt, sweat, and grime in every panel.

This isn’t horror in the traditional sense. It’s erotic, surreal, and emotionally jarring. What makes Keep on Vibrating so disturbing isn’t just the sex or the violence, it’s the complete erosion of normalcy.
There are moments of genuine brilliance hidden in the filth. Concepts or scenes that stick with you, not because they are shocking, but because they feel like they came from some dark, repressed corner of our subconscious.
Keep on Vibrating isn’t for most readers. If you’re looking for a truly disturbing experience, though, for something that goes beyond gore into psychosexual discomfort and surreal depravity, this one’s for you.

17 Misumisou

Misumisou is one of the most disturbing manga ever written. It’s not just the violence, it’s the sheer cruelty of it all. Set in a decaying rural town, the manga plunges headfirst into bullying, madness, and revenge, all revolving around middle schoolers.
Haruka Nozaki transfers from Tokyo and quickly becomes the target of merciless bullying. Her classmates torment her physically and emotionally, escalating the abuse with sadistic extremes. The one horrifying event changes everything. From here on out the manga plunges you into a bloody spiral of revenge, and increasingly deranged violence.
What makes Misumisou so disturbing isn’t just the gore, it’s the age of the characters. Kids stab each other, bash in skulls, and murder each other with relentless fury. The sheer viciousness feels wrong on a visceral level. Everyone, from the deranged bullies, to the cold, self-absorbed adults, seems morally bankrupt. Even the class teacher is unhinged.

The setting also adds to the horror. The town feels suffocating. The adults simply don’t care. Every interaction drips with indifference.
The art by Rensuke Oshikiri is polarizing. His characters wear grotesque, exaggerated expressions that border on cartoonish, but it also adds to the unsettling atmosphere. Once the violence hits, however, it hits hard.
Misumisou isn’t nuanced or subtle. It’s blunt, bleak, and emotionally exhausting. It’s a tale of teenage violence taken to horrifying extremes, and one of the most twisted revenge stories manga offers.

16. Hideout

Hideout is a short but deeply disturbing plunge into madness, grief, and unrelenting violence. Written and illustrated by Masasumi Kakizaki, this nine-chapter horror manga doesn’t waste a single page, and doesn’t give you room to breathe.
The story follows Seiichi Kirishima, a failed novelist on a remote island getaway with his wife. On the surface, it’s a trip to rekindle their strained relationship after the death of their child. In truth, it’s something far darker: Seiichi plans to murder her. When his attempt fails and she flees into the jungle, the real nightmare begins.
What follows is a psychological spiral soaked in anger, guilt, and psychosis. The cave they stumble into isn’t empty. Something twisted lurks within.

What makes Hideout so disturbing isn’t just the brutal violence, though. It’s the complete emotional breakdown of its character. Seiichi isn’t a tragic man. You slowly realize he’s a delusional, self-pitying monster. His internal monologue is chilling. His justifications feel real, even rational, until they don’t. By the time you reach the final chapter, the full weight of his descent hits like a gut punch.
The art is phenomenal, but oppressive. Heavy shadows, grim textures, and claustrophobic panels amplify the suffocating dread. Every page feels like it’s closing in on you.
There’s no hope here. No redemption. Hideout isn’t just a horror story. It’s a window into the mind of a deranged murderer, a masterclass in psychological horror, and one of the most disturbing manga ever written.

15. My Dearest Self With Malice Aforethought

My Dearest Self With Malice Aforethought is a psychological thriller that slowly morphs into one of the most disturbing manga I ever read. There’s scarcely any gore, no monsters, but instead the unraveling of identity, twisted relations, and a constant sense of dread that something is terribly wrong.
The story follows Eiji Urashima, a seemingly average college student who wakes up next to a girl claiming to be his girlfriend, yet he has no memory of her. Even worse, several days have passed that he can’t account for. It’s the start of a terrifying realization: Eiji might have another personality, one that’s living a separate life without his knowledge.
That premise alone is chilling enough, but My Dearest Self With Malice Aforethought doesn’t stop there. What begins as a mild case of dissociation spirals into something much darker. With each chapter, disturbing truths are unearthed. The twists are constant, each more harrowing than the last.

The first half of the manga is relentlessly paced, full of psychological tension and shock. You never feel grounded. Every new piece of information makes you question what’s real, who to trust, and what kind of monster might hide inside Eiji.
The second half slows down as the mystery narrows and the pieces slowly fall into place. Even then, the revelations remain dark.
This isn’t a horror manga, but it’s still deeply unsettling. It grips you with psychological fear and keeps you in a state of constant unease. If identity horror, unreliable reality, and mind-warping tension are what disturbs you most, My Dearest Self With Malice Aforethought delivers.
Genres: Psychological, Thriller, Mystery, Drama

14. Lychee Light Club

Lychee Light Club is a grotesque, fascist fever dream warped in adolescent sadism. Written and illustrated by Usamaru Furuya, this short but disturbing manga is a descent into madness, obsession, and eroticized violence, all carried out by a group of middle school boys.
The story centers on the Hikari Club, a secret society of boys who worship beauty and power. Together, they built a robot named Lychee, and programmed it to kidnap beautiful girls from town. Beneath their twisted quest lies something darker: the collapse of reason, the rise of authoritarian cruelty, and the violent fantasies of emotionally repressed youth.
From the opening chapter, Lychee Light Club announces itself with unflinching brutality. The violence is shocking, not just because of its graphic detail, but because it’s enacted by children. The tension between innocence and depravity makes this manga so disturbing.

The manga’s content is charged with psychosexual imagery, dismemberment, torture and psychological breakdown. But it’s the groupthink, the fascist, almost ritualistic loyalty to their leader that makes it feel truly disturbing. As power shifts, members betray one another, and ideology turns deadly.
Furuya’s art is clean and theatrical, almost too elegant for the subject matter. This contrast only heightens the grotesque. His character design, the staging, the drama, it all feels like a demented stage play, echoing the manga’s theatrical roots and Maruo-inspired ero-guro flair.
Lychee Light Club is sick, stylish and impossible to forget. A surreal horror opera of adolescent cruelty, where ideology, repression and violence twist together into an utterly disturbing manga.

13. Mr. Arashi’s Amazing Freak Show

Mr. Arashi’s Amazing Freak Show is one of the most disturbing manga ever drawn. Created by Suehiro Maruo, it blends ero-guro aesthetics, surreal imagery, and extreme cruelty into a haunting, tragic story that’s hard to forget and harder to stomach.
The plot centers on Midori, a young girl who is taken in, or rather enslaved, by a traveling freak show. Rather than finding refuge, she’s subjected to relentless cruelty from the twisted performers around her. What follows is a nightmarish journey through psychological and physical abuse, all rendered in Maruo’s elegant, classical art style.
The manga doesn’t rely on jump scares, but rather disturbing human behavior and the erosion of innocence. As the story progresses, Wonder Masamitsu joins the show, a mysterious magician whose illusions warp reality itself. From this point forward, the narrative grows stranger and more surreal, blurring the lines between dream and nightmare.

Even moments of tenderness are uncomfortable. The relationship between Midori and Wonder, is framed with care, but raises serious ethical questions, adding to the story’s deeply unsettling tone.
Mr. Arashi’s Freak Show is infamous not only for its content, but the way it presents it. It’s full of surreal theatricality, graphic metaphors and tragic inevitability. It’s not for everyone, and it’s easy to see why. For those who are willing to explore the darkest corners of the manga medium, however, it’s a disturbing and unforgettable experience.
Genres: Horror, Exploitation, Tragedy, Psychological

12. Soil

Soil is not disturbing in the usual sense. It doesn’t lead with gore or explicit horror. Instead, it creeps under your skin with surreal dread and creeping psychological rot. Created by Atsushi Kaneko, it begins as a quirky mystery and slowly mutates into something stranger, darker and profoundly interesting.
Set in the seemingly idyllic suburban community of Soil New Town, the story kicks off with a missing family. Two detectives, the foul-mouthed, unhinged Yokoi and his straight-laced partner, Onoda, arrive to investigate. The deeper they dig, however, the weirder the town becomes. Clues don’t add up, reality begins to slip, and it becomes clear that something is deeply wrong here.
What makes Soil disturbing isn’t just the secrets hidden behind the town’s carefully maintained facade, though there are plenty. From a council president who spies on residents with hidden cameras and drugs his dental patients, to teenage rapists, and massive harassment of those who don’t fit, Soil pulls no punches.

Even more disturbing, however, is the way the story dissolves into pure surrealism. The further you read, the less you understand. The town becomes a nightmarish echo of itself. The narrative collapses into a Lynchian fever dream where logic no longer applies.
Kaneko’s angular art style adds to the uncanny effect. At first it seems stiff, even cartoonish, but once the horror deepens and the visuals distort, it becomes expressive, perfectly capturing the dreamlike madness of Soil New Town.
If you want something disturbing not for what it shows, but for how it feels, Soil is one of the most jarring and disquieting manga out there.

11. Franken Fran

Franken Fran is one of the most bizarre and disturbing manga ever. Created by Katsuhisa Kigitsu, it follows Fran Madaraki, a kind-hearted but completely unhinged surgeon created by a legendary doctor. When he disappears, Frank takes over his work, often with disastrous, grotesque, and darkly hilarious results.
Told in episodic format, the manga functions like a twisted anthology, each chapter representing a new patient, and a new horrifying outcome. Franken Fran is like a weird version of Tales From the Crypt full of sci-fi body horror.
What makes it so disturbing is its unapologetic focus on surgical and medical horror. Organs, brains, intestines and much more are laid bare. Fran routinely cuts people open, rearranges their anatomy, reanimates corpses, or transforms humans into monstrous versions of themselves.

Even the more comedic or satirical chapters are drenched in grotesque visuals. A chapter may seem lighthearted at first until someone’s body mutates, degenerates or collapses in freakish, biological plausible ways. The manga never lets you get comfortable.
There’s also Fran herself. Cheerful, polite, and always eager to help, she’s a walking contradiction. She genuinely wants to help people, but her solution often ignores morality, sanity or the patient’s wishes. She’ll perform groundbreaking surgery without hesitation, even if the result is a permanent nightmare.
Franken Fran is equal parts horror, sci-fi and black comedy. Some chapters miss the mark, especially the lighter ones, but at its best it’s a gleefully perverse exploration of body horror and medical ethics gone wrong. Disturbing, weird, but also charming. An unforgettable read.

10. Starving Anonymous

Starving Anonymous is a grotesque descent into industrialized horror, where humans are no longer people but livestock. Co-created by Yuu Kuraishi and Kazu Inabe, it’s one of the most viscerally disturbing manga of the last decade, not just for its gore, but for the systematic, mechanical way it dehumanizes its victims.
The story begins with two high schoolers, Ie and Kazu, who wake up inside a freezing truck filled with corpses. They’ve been abducted and brought to a secret facility that breeds, fattens, and processes humans like animals. It’s not just violent, it’s disturbingly methodical.
At the heart of it all are monstrous, insectoid creatures that feast on humans. Their presence turns every feeding scene into a nightmare: people are devoured alive, torn limb from limb, or reduced to pulp in seconds. What’s truly unsettling, though, isn’t the gore itself, but how accepted it all is. The world treats human suffering as nothing but a routine.

The manga also explores forced reproduction, bodily autonomy, and scientific horror. People are not only killed, they’re repurposed and reshaped all under the guise of cold efficiency.
The artwork enhances every disturbing moment with surgical precision. Skin and flesh stretch, eyes bulge, and organs are exposed.
Starving Anonymous eventually shifts into high-concept sci-fi, but the unsettling factor never fades. It’s not just the violence that lingers, but the horrifying idea of a world where people are nothing but feed. If you’re disturbed by exploitation, dehumanization, and body horror on a massive scale, this manga will stay with you.

9. Wolf Guy: Ookami no Monshou

Wolf Guy: Ookami no Monshou is one of the most disturbing action-horror manga ever written. Behind its stylish art and supernatural premise lies a manga drenched in brutality, suffering, and unflinching cruelty. It’s not just violent, it’s twisted.
The story follows Akira Inugami, a mysterious transfer student who hides a dark secret: he’s a werewolf. He heals instantly, doesn’t age like a normal human being, and tries to live in peace. Peace, however, isn’t an option.
At first, the disturbing content is rooted in physical violence. We see vicious beatings, mutilations, and brutal fights. Then the manga escalates. It dives into a series of graphic, traumatic events, including torture, sexual assault, and a harrowing school shooting. There’s even a prolonged arc involving the sexual abuse of a central character that’s among the most difficult scenes in any manga to sit through. These chapters alone have caused readers to drop the series, and understandably so.

What makes Wolf Guy: Ookami no Monshou so disturbing isn’t just what happens, but how relentlessly the manga rubs it in your face. The characters, especially the antagonist, Haguro, are pure chaos and sadism incarnate. There’s no comfort here, just escalating carnage.
Yet Wolf Guy: Ookami no Monshou is strangely mesmerizing. Akira is a tragic, stoic figure, a supernatural being constantly haunted by the worst of humanity. The artwork is cinematic and raw, delivering gorgeously stylized sequences that only make the suffering hit harder.
If you’re looking for a disturbing manga that pushes the boundaries of what’s acceptable, Wolf Guy: Ookami no Monshou is unforgettable.

8. MPD Psycho

MPD Psycho is one of the most disturbingly cerebral crime-horror manga ever written. Created by Eiji Otsuka and drawn by Shou Tajima, it’s not shocking for the sake of it. Instead, it’s cold, methodical, and haunting in ways that linger long after the gore fades.
The story follows Kazuhiko Amamiya, a detective with a dissociative identity disorder. At first, it reads like a gruesome procedural, depicting grotesque serial killings. The longer the manga goes on, however, the narrative unravels into a deeply psychological web of identity, mind control, and institutional horror.
The violence here is horrifying, not just because of what is shown, but how it’s shown. Victims are dissected, mutilated, and repurposed into grotesque installations: heads turned into flowerpots, people made into grotesque sculptures, organs and limbs removed with surgical precision. There’s no rage behind the killings, just disturbing detachment.

Tajima’s artwork heightens the discomfort. Every wound, every expression, every corpse is drawn with clean, cold lines. There’s no mess, just sterile medical precision that makes the violence feel eerily real.
It’s not just the visuals, though. MPD Psycho is disturbing on a psychological level. The fractured identities of its protagonist mirror the fragmented narrative, and the manga constantly questions what it means to be a person. It’s deeply unsettling to imagine suffering from the mental condition depicted here, especially within a world so devoid of empathy.
This isn’t splatterpunk. It’s horror filtered through logic, cruelty, and control. MPD Psycho is dense, brutal, and demanding, but it’s also one of the most intelligently disturbing manga of its kind.

7. Blood on the Tracks

Blood on the Tracks is psychological horror at its most intimate, and its most disturbing. Created by Shūzō Oshimi, it follows Seiichi Osabe, a quiet middle schooler, and his overbearing mother, Seiko. What begins as slightly uncomfortable affection quickly spirals into one of the most terrifying portrayals of emotional abuse in manga.
There’s no gore, there’s no supernatural twist. Just a mother who watches too closely, holds on too tightly, and slowly erases her son’s sense of self. Early on, one single, horrifying act shatters the illusion of domestic safety. From that moment, Blood on the Tracks becomes a suffocating descent into psychological control.
What makes this manga so disturbing is not just Seiko’s behavior, but how subtly and relentlessly she exerts power over every moment of Seiichi’s life. He’s never alone. She’s always there: hovering, listening, watching. Her blank stares and forced smile carry more dread than any monster ever could.

Oshimi’s artwork amplifies the tension with masterful restraint. Entire chapters focus on a single glance, a moment of silence, or a child too scared to speak. There’s an unbearable weight in every panel, an invisible grip tightening around Seiichi’s life, until it feels like he might disappear completely.
Even as the pacing slows towards the end, the damage is already done. The true horror here is watching a child’s will dissolve under constant, calculated love twisted into control.
Blood on the Tracks is slow, quiet, and absolutely suffocating. It’s a disturbing masterpiece of emotional horror, and one of the most disturbing manga in recent history.

6. Ichi the Killer

Ichi the Killer is one of the most psychologically disturbing manga ever created. Written and illustrated by Hideo Yamamoto, it’s a deep dive into trauma, sadism, and the darkest extremes of human behavior.
The story follows two broken men on a collision course: Kakihara, a sadomasochistic yakuza who lives for pain, and Ichi, an emotionally stunted young man manipulated into becoming a killer. Ich is no cold killer, though. He’s a trembling, confused boy whose mind has been systematically twisted. This contradiction between innocence and carnage makes the manga so horrifying.
The violence in Ichi the Killer is extreme, but not senseless. It’s disturbing because it’s so deeply rooted in psychology. People are tortured, raped, and mutilated, but the manga focuses not just on what is done, but why. Kakihara’s obsession with pain, Ichi’s collapsing identity, and the manipulation behind his actions are all deeply unsettling. You’re not just witnessing cruelty, you’re seeing how it’s born, fed, and weaponized.

Yamamoto’s gritty, chaotic art enhances the discomfort. The visuals are messy, visceral, and uncomfortable. Every act of violence feels personal, almost intimate, and every character is damaged beyond repair.
What makes Ichi the Killer truly disturbing isn’t just the graphic content, but the terrifying way it explores the human psyche.
This isn’t just a disturbing manga. It’s a psychological horror story masquerading as a crime drama. One of the most twisted, thought-provoking, and unforgettable titles out there.
Genres: Crime, Psychological, Gore

5. Homunculus

Homunculus is one of the most disturbing psychological manga ever created, but not because of gore or violence, but because of the raw, unfiltered descent into madness it portrays. Written by Hideo Yamamoto, it’s an exploration of trauma, perception, and identity that grows increasingly surreal the deeper you go.
The story follows Susumu Nakoshi, a man living in his car on the edge of society. When he agrees to undergo trepanation, a procedure in which a hole is drilled into the skull, his life changes. He begins to see people not as they are, but as symbolic, twisted representation of their inner trauma: homunculi.

These grotesque visions form the visual backbone of the manga. Melted features, fused limbs, literal manifestations of emotional scars. Each encounter becomes more unsettling than the last. But Homunculus goes far beyond body horror. It’s disturbing because it asks you to sit inside a mind unraveling. As Nakoshi spiral further from reality, it becomes harder to separate hallucination from truth, metaphor from madness.
The manga also heavily features sexual dysfunction and psychological manipulation. Several scenes blur the line between desire and trauma, identity and delusion. Yamamoto doesn’t shy away from uncomfortable territory, especially in his portrayal of gender, shame, and repressed emotions.

By the final arc, Homunculus fully abandons conventional storytelling and dives into surreal ambiguity. It’s baffling, but intentionally so. What begins as a simple experiment becomes a nightmare of fractured identity and existential dread.
If you’re looking for horror deeply rooted in psychology, symbolism, and the grotesque nature of self, Homunculus is one of the most disturbing manga you’ll ever read.

4. Freesia

Freesia is a disturbing descent into madness, set in a world where vengeance is legal. Created by Jiro Matsumoto, this manga imagines a near future Japan where victims’ families are granted the legal right to kill their loved one’s murderer, or hire someone to do it for them.
Our main character, Kano, is one such professional proxy killer. Even disturbingly, however, he suffers from schizophrenia, hallucination and severe memory lapses. From the very first chapter, it becomes clear that we’re not just witnessing a dystopia, but that we’re trapped in a man’s fractured mind. What makes Freesia so unnerving is how well it blurs reality and delusion. We can never be sure what’s real, and neither can Kano.

But it’s not just the protagonist who’s unraveling. Nearly every character in Freesia is mentally unstable or emotionally broken. Delusions, trauma, and psychosis run rampant.
While the story features violence, assassination, and cruelty, the most disturbing element is the bleak emotional core. We’re shown the victims‘ personal lives, their regrets, their humanity, and then we watch them being killed. Justice is mechanical, senseless, and soul-crushing.
Matsumoto’s harsh, sketchy art style adds to psychological unease. Dialogue is disjointed. Action scenes dissolve into chaos. The world of Freesia is claustrophobic and toxic, like a fever dream.

Freesia is not a clean tale of revenge. It’s a slow, depressing spiral into institutionalized violence, paranoia, and insanity. This manga is pure psychological rot. It’s uncomfortable, messy, and utterly disturbing in the way it portrays insanity, not as an exception, but as the rule.

3. Uzumaki

Uzumaki is one of the most bizarre, iconic and deeply disturbing horror manga ever created. A surreal masterpiece by Junji Ito, it takes a single abstract concept, the spiral, and turns it into a cosmic curse that wraps everything in its path.
Set in the foggy coastal town of Kurouzu-cho, Uzumaki follows Kirie Goshima and Shuuichi Saitou as they witness their home descend into madness. There are no monsters to fight, no antagonists to overcome. There’s only the spiral: a faceless, incorporeal force that infects minds, bodies, and reality itself.

What makes Uzumaki so disturbing is both its imagery and its implications. Right from the first chapter, we’re introduced to grotesque body horror as Shuuichi’s father becomes obsessed with spirals, an obsession that culminates with one of the most shocking pages in horror manga history. From there, things only escalate. People’s bodies twist unnaturally, faces spiral inwards, and so much more.
Certain chapters are especially unsettling for how far they push boundaries, and I break down the worst in this companion list.
The first two volumes unfold as episodic horror tales, each centered on a new spiral-related horror. Only the final volume shifts the manga into a Lovecraftian apocalypse.

Junji Ito’s masterful art and nightmarish imagination are on full display throughout the series. His surreal, intricate panels bring every warped transformation to life. And yet, Uzumaki’s horror goes beyond gore. It’s true terror lies in the helplessness o fit all. The spiral simply is. Its pull is inevitable.
Uzumaki is more than just one of the most disturbing manga ever made. It’s one of the greatest achievements in horror manga history.

2. Berserk

Rest in peace, Kentaro Miura. Thank you for sharing your gift with the world.
Berserk isn’t just one of the greatest manga ever written, it’s also one of the most disturbing. It’s a towering achievement in dark fantasy. It’s as brutal as it is beautiful, filled with nightmarish violence, unforgettable characters, and some of the most harrowing scenes in manga history.
The story follows Guts, the Black Swordsman, a lone warrior locked in an endless battle against demonic apostles and the man who betrayed him: Griffith. What begins as a bleak revenge tale gradually opens into an epic tragedy of fate, trauma, and survival.
The world of Berserk is hellish. War, rape, torture, and senseless slaughter are commonplace. Kentaro Miura never flinches from showing the worst of humanity.

The apostles are amongst the most grotesque, viscerally designed creatures in all of manga. Their monstrous forms are a showcasing for Miura’s artistic brilliance and his ability to render terror in staggering detail.
Yet even the most horrific imagery pales compared to The Eclipse, one of the most soul-crushing sequences in manga history. It is a moment so violent, so traumatic, and so devastating that it defines Berserk’s reputation.

Even after all this, though, Berserk remains a deeply human story. Guts is not a cold-blooded killer, but a man fighting to retain his soul. His suffering is immense, but his will seems unbreakable.
Berserk is disturbing, but it’s also transcendent. Miura’s art reaches heights few manga have ever touched. His panels are incredibly detailed, and in later arcs, reading the manga often feels more like staring at classical illustrations.
If you can handle its content, Berserk is a masterpiece. It’s an emotionally devastating, violently cathartic tale that deserves its place among the best manga ever made.

1. Fraction

Fraction is one of the most brilliant, bizarre and disturbing manga ever created. Written by Shintaro Kago, the undisputed king of absurdist horror, it starts as a gruesome serial killer mystery before completely shattering the boundaries of the narrative.
At first, the manga follows the case of the Slicing Devil, a brutal killer who murders victims by slicing their bodies in half. It’s grotesque, graphical, and unsettling on its own. But then, in true Kago fashion, the story turns inside-out: the author himself appears as a character and begins dissecting the manga’s structure.
What follows is a mind-melting, meta-narrative deep dive. Kago’s character lectures readers on horror tropes, story progression and authorial intent, while simultaneously becoming part of the narrative himself. It’s one of the most inventive uses of metafiction in horror manga, culminating in a twist so smart and unexpected it’s jaw-dropping.

And then, true to form, Kago returns to the Slicing Devil, but here the story descends into pure grotesque absurdity.
Yet Fraction doesn’t stop there.
The second half of the volume features standalone short stories, each stranger than the last. The most disturbing by far is Voracious Itch. It’s an unforgettable piece of body horror so viscerally disgusting and vile, that it’s hard to read and harder to forget. It’s not just grotesque, it’s pure nightmare fuel.
Fraction is chaotic, offensive, and structurally insane, but it’s also a masterpiece of experimental horror. If you have the stomach for it, and love seeing form and genre torn apart, check this manga out. Just don’t expect to sleep well after.
