Anime You Should Be Watching (Horror Edition): Angel of Darkness (Injū Kyōshi)


shokushu zeme: “tentacle attack” erotica that explores taboo themes using tentacle-based sexual fantasy as a narrative and visual motif to circumvent Japanese censorship laws.

Angel of Darkness (Injū Kyōshi) holds a notorious place in the lineage of erotic horror anime, bridging the transgressive extremities of Chōjin Densetsu Urotsukidōji and the occult eroticism that would later define Bible Black. This four-episode OVA series from 1994 encapsulates the tentacle horror subgenre with uncompromising explicitness, wrapping its unsettling imagery in a narrative set within the seemingly innocent confines of a girls’ boarding school. The series exemplifies a distinctive moment in adult anime history, when grotesque sexuality and supernatural horror merged to explore themes of control, corruption, and forbidden knowledge.

Like UrotsukidōjiAngel of Darkness does not shy away from cataclysmic violence or graphic sexual transgression. However, rather than sprawling cosmic battles and apocalyptic carnage, it opts for a claustrophobic setting where the boundaries between predation and education collapse. The boarding school, an archetype of sheltered innocence, becomes a crucible for spiritual decay where evil—in the form of demonic possession and twisted rituals—lurks beneath routine façades. This subversion of a sacred educational environment highlights the series’ investment in moral and sexual transgression as intertwined forces.

The plot centers on Professor Goda, whose discovery of a strange stone beneath a campus tree unleashes an ancient, tentacled spirit that begins a viral corruption throughout the school. His transformation into a monstrous sex demon initiates an escalating cycle of ritual abuse and possession among the students and faculty. Against this backdrop, the developing relationship between Sayaka and Atsuko—the relatively innocent lovers trying to find connection amid chaos—provides a tragic human center to the nightmarish events unfolding. The series’ focus on lesbian romance adds emotional depth while diverging from typical harem or fetishistic formulas, instead using sexuality as both refuge and vulnerability under the shadow of demonic influence.

The narrative frequently returns to graphic scenes of domination, bondage, and forced extraction of bodily fluids, imagery that serves symbolic purposes as much as titillation. The recurring S&M rituals, scenes of rape by tentacles, and the desecration of once-hallowed spaces—such as the chapel turned site of torment—communicate a profound collapse of innocence and spirituality. This fusion of sex, violence, and the supernatural positions Angel of Darkness not as mere pornography, but as a stark allegory for power, control, and the corruption of purity.

Visually, the series operates within the constraints of mid-1990s adult OVA budgets, but its simplistic, shadow-heavy animation effectively evokes a mood closer to gothic horror than glossy erotica. The color palette is muted, alternating between the sterile luminescence of the school’s daytime routine and the ominous shadows of ritual scenes. This dichotomy underscores the narrative’s tension between surface normality and subterranean evil. Though the character designs lack the polish of contemporary works like Bible Black, with rougher lines and stilted motion, these limitations amplify the uncanny atmosphere, making the viewer uneasy in a way polished animation rarely achieves.

Sexual content dominates explicitly and persistently, refusing to separate eroticism from horror. This integration exemplifies Angel of Darkness’ commitment to challenging viewer boundaries and expectations. The tentacle horror motifs—ubiquitous in the genre but here rendered with disturbing severity—represent not just physical assault but a symbolic invasion of autonomy and identity by dark forces. The series’ interest in bodily horror situates it firmly within the tradition of Japanese erotic horror, yet its blend of sexuality with a narrative of supernatural possession elevates it beyond titillation toward a meditation on corruption and loss of self.

The series’ narrative and visual style contributed significantly to the evolution of adult anime as a genre willing to explore complex themes within erotic content. It is a clear spiritual predecessor to later occult-erotic works such as Bible Black, which would refine this formula with denser storytelling and atmospheric lighting but owe much to Angel of Darkness’ bold fusion of sex and the supernatural. The taboo-challenging spirit of the series also helped popularize tentacle pornography as a distinctive fetish category internationally, with Angel of Darkness frequently cited as a touchstone in underground anime communities.

Critically, Angel of Darkness remains polarizing. Its extreme explicitness and depiction of violent, non-consensual acts alienate many viewers while fascinating others with its raw thematic ambition. While it is impossible to discuss the anime without acknowledging its deeply problematic content, dismissing it purely as objectionable obscenity overlooks its place as a cultural artifact that pushes the limits of storytelling in adult animation. Indeed, the series critiques institutional complicity and the violation of trust—from teacher to student, from sacred institution to corrupted shrine—embedding its sexual horror within a larger allegory for power abuse.

Despite—or perhaps because of—its intense imagery, Angel of Darkness has maintained a lasting cult status for nearly three decades. Its influence reaches beyond hentai audiences, with many anime historians and scholars referencing it as a foundational work in the erotic horror niche. Its legacy is one of transgression not just for shock, but as a deliberate aesthetic and narrative strategy that challenges the viewer’s comfort zones and probes darker aspects of desire and domination.

Ultimately, Angel of Darkness is a complex and disturbing work that defies simple categorization. It is a horror anime that uses explicit sexuality and supernatural menace to explore themes of corruption, power, and forbidden love. As a historical piece, it represents both the creative ambition and the social taboos of 1990s adult Japanese animation, offering a grim yet compelling experience for those prepared to confront its darkness.

Anime You Should Be Watching: Bible Black (Baiburu Burakku)


eroge: is a portmanteau of erotic game. It is a Japanese video or computer game that featured erotic content (usually pornographic in nature) and used anime-style artwork in a visual novel format.

Hentai as a genre first reached wide recognition through the notorious Chōjin Densetsu Urotsukidōji, a 1980s OVA that fused graphic sexual imagery with apocalyptic horror and violent fantasy. That work established many of the conventions that would define adult anime for decades—its blend of mythology, grotesque excess, and surreal eroticism pushing the boundaries of animation’s narrative potential. Bible Black represents a later evolution of that tradition, taking the transgressive energy of Urotsukidōji and refining it through a more contained setting, structured storytelling, and psychological tension. Where its predecessor reveled in grandiose chaos, Bible Black turned inward, exploring horror through ritual, secrecy, and moral decay within familiar, everyday environments.

Originally developed as an eroge visual novel, Bible Black featured the artwork of its creator, Shoujo Sei. The game’s popularity within Japan’s adult gaming market grew rapidly, fueled by its striking blend of erotic storytelling, occult imagery, and a sinister undercurrent that set it apart from typical romantic visual novels of its time. Its success inevitably drew the attention of Milky Studio, an animation company already known for adapting adult-oriented games into OVAs. Within a few years, Milky Studio produced the first Bible Black anime series—a six-episode OVA that closely followed the storylines and choices from the original game.

The anime adaptation centers on a high school caught in a web of witchcraft and forbidden rituals. While the premise may sound familiar to fans of the supernatural or occult genres, Bible Black distinguished itself by merging sexual and mystical elements in a way that felt both deliberate and unsettling. The first OVA mirrors the game’s basic storyline, introducing viewers to a world where innocent facades collapse under the weight of temptation and corruption. Later sequels and prequels expanded on this mythology, delving into the origins of the dark book that drives the narrative and introducing new characters entangled in its influence. In doing so, the series built a continuity resembling a twisted mythos—an interconnected body of stories that deepened its immoral mystique.

To describe Bible Black merely as “popular” within its niche would be an understatement. Its reputation extends far beyond its target audience, circulated through anime forums, recommendation threads, and cultural commentary as a kind of benchmark for erotic horror. It is the title almost universally cited when discussing adult-oriented anime, whether out of reverence for its artistic boldness or infamy for its transgressive imagery. For many viewers—particularly Western audiences in the early 2000s—it represented their first exposure to Japanese erotic animation beyond parody or rumor, granting it a strange, almost legendary status within the genre’s history.

What separates Bible Black from lesser works is the precision with which it fuses its erotic and occult motifs. The narrative’s backbone—the pursuit and misuse of a magical grimoire—offers an allegory for unchecked desire and the cost of power. Rituals blend seamlessly with acts of seduction, and the visual motifs of pentagrams, candles, and bloodstained rites serve as metaphors for obsession and spiritual decay. This combination gives the anime an intensity uncharacteristic of typical adult fare, as every encounter is charged not only with physical desire but also with moral and supernatural consequence. Rather than treat sexuality as isolated spectacle, the series enfolds it within its darkly coherent world, ensuring that sin and pleasure remain inseparable.

The “harem” narrative structure, common to many eroge and visual novels, is used here with a more perverse edge. The typical male protagonist surrounded by female admirers becomes a focal point not of romantic fulfillment, but of temptation and corruption. In Bible Black, that dynamic is steeped in manipulation and control—sex as both a weapon and a spiritual act. This inversion of a familiar trope contributes to the series’ enduring fascination, as it refuses to comfort the viewer with the conventions of fantasy romance. Instead, it constructs an atmosphere of moral ambiguity and psychological pressure, leaving few characters untainted.

The setting amplifies the discomfort. By situating its story within the environment of a high school—a space symbolically associated with innocence and growth—Bible Black subverts expectations. The classrooms and corridors that should represent order and safety become arenas for forbidden rites and hidden depravity. This juxtaposition between the mundane and the macabre intensifies the sense of violation that defines the series. It’s not only a story of erotic ambition but of how institutional and moral structures collapse when confronted by unchecked desire and occult power.

Visually, the anime reflects its early-2000s production values with surprising sophistication. Milky Studio preserved the visual style of Shoujo Sei’s original artwork—marked by angular features, bold contrasts, and expressive eyes—while enriching the material with atmospheric lighting and strong sense of color. The palette alternates between the sterile brightness of school life and the dim, saturated tones of ritualistic scenes, crafting a visual rhythm that heightens tension between two worlds. Despite the limited resources typical of an OVA, the series achieved a memorable aesthetic identity, merging the glossy surfaces of contemporary anime with the raw suggestiveness of eroge art.

As Bible Black expanded into sequels like Bible Black: New Testament and various side stories, its universe deepened both narratively and tonally. The newer installments explored different perspectives and timeframes, revealing the long shadow of the original events. This serial approach—rare for hentai productions—allowed the franchise to form a loose continuity, almost like a dark fantasy saga built around erotic and esoteric principles. The cumulative effect was that Bible Black ceased to be a one-off novelty and became a defining thread in the history of animated erotic horror.

Its cultural impact extends further still. Bible Black served as one of the first major adult anime titles to gain substantial attention outside Japan during the rise of online fan communities. Through fan distribution and unofficial translations, it became many Western viewers’ first encounter with themes such as futanari—depictions involving gender transformation or dual sexual anatomy—which had previously remained obscure outside Japan. The OVA thus became not only a product of its domestic industry but also a cultural export that introduced global audiences to the specialized lexicon and aesthetics of Japanese hentai.

Critically, Bible Black remains an object of contention. Its explicitness renders it indefensible to some, yet others recognize within it a degree of thematic intent that surpasses mere sexual provocation. It approaches the occult not with romantic mysticism, but as an allegory for moral erosion and human vulnerability. Erotic acts in the series often parallel spiritual corruption, suggesting that the boundary between pleasure and damnation is perilously thin. The result is an anime that provokes both physical and intellectual reactions—equally discomforting in its carnality and symbolism.

Even after more than two decades, Bible Black maintains relevance and recognition. Later works have tried to replicate its formula—mixing fetishes with supernatural dread—but few possess its coherence or audacity. Its imagery, tone, and structure continue to influence adult creators seeking to merge explicit content with narrative ambition. Moreover, the series exemplifies a moment in anime history when the medium’s adult side dared to pursue storytelling complexity rather than rely solely on erotic novelty.

Viewed today, Bible Black endures as both time capsule and touchstone. It captures an era when the boundaries between mainstream anime and adult experimentation briefly blurred, and when eroge culture translated successfully to animation with both narrative depth and artistic conviction. Whether judged as an expression of taboo horror, a stylistic artifact of its generation, or a benchmark for the fusion of sex and the supernatural, Bible Black stands as one of the most distinctive and controversial works in anime’s underground lineage. Its lasting infamy, like its allure, lies in its refusal to separate desire from darkness—a union as seductive as it is terrifying.

Anime You Should Be Watching: Chōjin Densetsu Urotsukidōji


Hentai: slang for the Japanese term “hentai seiyoku” which literally means sexual perversion. A word used by Western fans of anime to signify anime/manga as being of the pornographic variety.

In 1990, during my junior year of high school, I was introduced to a form of animation unlike anything I had known before—the darkly imaginative and transgressive world of hentai. While explicit Japanese media had existed long before, the particular title that marked my first encounter with the genre was Chōjin Densetsu Urotsukidōji. The work did not simply define hentai; it transformed how adult animation would be viewed by audiences in both Japan and the West.

Prior to its release, erotic or explicit manga had long circulated quietly within Japan, often categorized separately from mainstream entertainment. Yet when mangaka Maeda Toshio’s Chōjin Densetsu Urotsukidōji was adapted into animation by director Takayama Hideki in the late 1980s, something shifted. The result was a film that combined the grotesque, the apocalyptic, and the erotic into a single overwhelming experience. Takayama’s adaptation was not content to merely illustrate Maeda’s ideas—it amplified them into a fever dream of violence and desire that pushed the medium into territory rarely explored in animation.

This era in Japanese media was also defined by strict obscenity laws. Direct depictions of genitalia or explicit intercourse were prohibited, both in live-action and animation. To circumvent these limitations, artists employed mosaics or invented visual metaphors. Takayama approached the problem with disturbing creativity: he replaced human anatomy with monstrous, tentacle-like appendages. These served a dual purpose—they satisfied censors while reinforcing the story’s occult and otherworldly atmosphere. Inadvertently, this gave rise to one of the most infamous tropes in hentai culture: “tentacle rape.” What began as a method of evading censorship evolved into a symbol of perversion, horror, and fascination.

Though Maeda initially regarded Takayama’s interpretation as excessively cruel and sadistic, he expressed admiration for the director’s ability to explore the darker undercurrents of his story. In time, Maeda’s own works would adopt similar motifs, blending eroticism with the supernatural. His later projects—including Yōjū Kyōshitsu GakuenAdobenchā Kiddo, and the enduring Injuu Gakuen La Blue Girl—refined the sensibilities born from Urotsukidōji, mixing violence, humor, and demonic imagery. These works often shifted in tone but never strayed far from the genre’s defining combination of horror and sexual excess.

Chōjin Densetsu Urotsukidōji can best be described as a collision of disparate influences: the mythic nihilism of H. P. Lovecraft, the explicit confrontational style of Larry Flynt, and the occult transgression of Aleister Crowley, all underscored by the philosophical cruelty associated with the Marquis de Sade. The film’s narrative combines apocalypse with pornography, constructing a universe where gods, demons, and humans become locked in violent and erotic cycles of destruction and rebirth. It is both a nightmare and a spectacle, a work that examines desire as an extension of cosmic chaos.

Watching the OVA as a seventeen-year-old was an experience of shock and bewilderment. Nothing in my understanding of animation prepared me for it. The optimism and adventure of series like RobotechStarblazers, and Voltron stood in stark contrast to the nihilistic intensity of Urotsukidōji. If such a term had been common at the time, “culture shock” would have described it perfectly. Yet beyond my initial disorientation, I recognized something compelling beneath the shock value—a strange vision that treated eroticism not as mere indulgence but as a reflection of human fear and fascination.

Takayama’s film succeeded because it used obscenity as both spectacle and metaphor. The sexualized violence was horrifying, but it also emphasized the collapse of moral order within its world. The boundaries between sensuality and monstrosity blurred, suggesting that both sprang from the same primal source. In this way, Urotsukidōji transformed its limitations into aesthetic strength. Censorship forced invention, and invention created symbolism: the tentacle became an image of corruption, domination, and inhuman desire.

When Urotsukidōji began circulating in the West through VHS imports in the early 1990s, it acquired immediate notoriety. For many international viewers, the notion that animation could contain such extreme imagery was almost unthinkable. Western audiences, accustomed to animation as a medium for children or adolescent adventure, suddenly encountered a work that combined cinematic brutality with mythology and eroticism. Owning or viewing it became an act of curiosity and defiance. Accessing such media often meant seeking imported tapes or attending small conventions—a process that only heightened its sense of exclusivity and taboo.

Not everyone perceived Urotsukidōji as art. Its reputation became divisive; for some, it represented the most exploitative and grotesque tendencies of Japanese culture, while to others, it was a bold exercise in creative freedom. Regardless of one’s stance, its influence was undeniable. The film inspired countless imitators, establishing a visual and thematic template for subsequent hentai and “erotic horror” animation. Even as later works diversified into comedy, fantasy, and romance, the long shadow of Urotsukidōji remained.

There is also a deeper irony in its legacy. The same adaptation Maeda once criticized expanded the reach and visibility of his creation beyond what any manga publication could have achieved. The collaboration between artist and director—however fraught—produced a convergence of imagination that shaped both the erotic and horror dimensions of modern anime. In a broader sense, it demonstrated that the animated form could explore the same depths of transgression, myth, and existential dread that live-action cinema often reserved for its most daring auteurs.

Seen through this lens, Urotsukidōji becomes more than a piece of pornographic shock cinema. It emerges as a cultural artifact—one that reflects how desire, repression, and fantasy intersect within specific historical and artistic contexts. The work exposes how censorship and creativity can collide to produce unexpected invention, and how audiences, whether through fascination or outrage, help define a genre’s legacy.

For those of my generation, encountering Urotsukidōji was a defining moment that reshaped perception. It suggested that animation could express not only beauty and adventure but also the darker instincts of the human psyche. What began as disbelief evolved into a kind of reluctant respect for its ambition. Beneath the grotesque imagery lay a thematic depth that continues to invite examination—questions about power, violation, and the thin line separating horror from desire.

Today, both Maeda Toshio’s manga and Takayama Hideki’s adaptation occupy a controversial yet essential place in the history of Japanese media. They are remembered not only for their sensational content but for their cultural and aesthetic audacity. The story of Chōjin Densetsu Urotsukidōji endures because it refuses simplification—it is at once abhorrent and visionary, obscene yet strangely philosophical.

From the most ardent anime historian to the casual viewer, its reputation persists. Whether reviled or revered, Urotsukidōji remains the ultimate symbol of hentai’s origins and its infamous reach. It stands as both a warning and a testament: that art, when unfettered by convention and driven by instinct, can explore places society dares not name.

Review: Slither (dir. by James Gunn)


James Gunn first got his chance to work in the horror-comedy genre with his time in Troma Films. His first contribution to the genre being a send up of Shakespeare’s Romero and Juliet aptly titled as Tromeo and Juliet. He next moved on to penning scripts for the major studios with his first two being the critically-panned, but profitable two Scooby-Doo live-action films. Gunn next moved on to writing a script reimagining George A. Romero’s classic Dawn of the Dead. Despite howls of protest from the original film’s legion of fans, the film went on to be a modest success and helped bring about the renaissance of the current zombie mania in all facet of entertainment. Gunn follows up the success of his Dawn remake by not just writing the script but finally getting behind the camera and directing it himself. I’m glad to say that James Gunn’s first directorial debut with Slither has turned out to be one fun, gross-out, disgustingly hilarious horror-comedy that brings to mind the splatter-comedy films of the 1980’s.

I say that Slither has alot in common with the horror-comedy during the 80’s just for the fact that we’ve not seen a film of this kind since. Slither brings to mind such 80’s B-movie shlock classics like Critters, Return of the Living Dead, and Night of the Creeps. But Gunn also pays some an homage to cult classics like John Carpenter’s The Thing. One of the character’s in the film and a store are even named after The Thing‘s badass antihero, R.J. MacReady. Then there’s the tip of the hat to Romero’s zombies, though this time around I would say that Gunn had more in mind the quickthinking and funny undead from John Russo’s Return of the Living Dead. There’s even a shout out to Invasion of the Body Snatchers as the alien slug-controlled populace are actually part of a much larger organism who thinks for all.

The story Gunn came up with for Slither was pretty straightforward and simple. Intelligent alien organism bent on world domination hitches a ride on a meteor which travel the depths of space until it falls on an unsuspecting planet. Unfortunately, the planet in question for the film happens to be Earth. Right from the get go the comedic aspect of the film begins even as the alien-laden meteor crash lands its way to one Wheelsy, N.C. A podunk town where the most interesting to happen each year is the annual Deer Cheer which signals the start of Deer Hunting season. We get to see the mundane day-to-day life of the townspeople from the pretty high school teacher Starla Grant (adorably played and with a strong sense of marital fidelity by Elizabeth Banks), the town’s obnoxious and foulmouthed Mayor MacReady (Gregg Henry’s performance was hilarious and he gets pretty much all the best one-liners), to its Chief of Police Bill Pardy (Nathan Fillion in Han Solo mode).

The alien soon finds a host in the town’s richest person who also happens to be Starla’s much older husband, Grant Grant. Michael Rooker (Henry: Portrait of a Serial Killer) plays Grant and his performance was both funny and sad. He pretty much starts morphing into a creature somewhere between Jabba the Hutt and a Lovecraftian squid-person. But through it all, Grant’s love for his wife manifests itself by way of the alien’s collective intelligence. When the townspeople all start getting infected by the large, slug-like offsprings of the main alien, it’s hilarious to find that they all share Grant’s love for Starla. It would seem that the alien collective learned abit or two from Grant about marital love and also a love of Air Supply’s syrupy ballad, “Every Woman in the World.” These zombies chant the word “Starla” instead of “brains.” The rest of the film was pretty much Starla, Bill Pardy and a small band of survivors trying to stop the Grant-alien, the slugs and the zombified townspeople from spreading out of Wheelsy and out onto the rest of the planet.

The film balances well between horror and comedy. The horror aspect of Slither comes from the many gory scenes. Trust me when I say that this film has more than its share of blood, gore and splatter. We’re shown dead and gutted pets and farm animals. Not to mention the requisite flesheating performed by the zombies. the great thing about the scenes of horror in Slither was the absence of CGI except for a scene or two and even then it was difficult to pinpoint which was CGI and which was animatronics and make-up effects. Slither‘s monster effect owes alot to the work of Rob Bottin and his crew who did the disgustingly creative effects on Carpenter’s The Thing. I’m glad to see that Gunn decided to forgo CGI for these scenes and went for more realism. Even if such realism were nauseatingly disgusting and gross. Just what a horror movie was suppose to be. The comedy part came not from the aliens and the scenes of horror, but from the characters reactions to the unfolding events around them.

Just like Shaun of the Dead, Slither’s characters stumble, bumble and trip their way through the crisis. Even Fillion’s character of Bill the Chief goes against the stereotypical hero from these type of film. He’s a smartass about his job and how he sees the people he’s suppose to protect, but when the time comes to do his job as protector he tries to do the best he can even though the best he can doesn’t measure up to what we’re suppose to get from our heroes. The dialogue was fast and wickedly sharp which made for alot of hilarious one-liners and most of them coming from the mouth of Slither’s Mr. Pibb-obssessed Mayor MacReady and his penchant for overreacting to everything and also for calling everyone cocksucker.

Slither doesn’t try to be anything but what it set out to be: a funny horror film with a large helping of slapstick, splatter and slime. In that respect, James Gunn succeeded with his writing and directing of Slither. The movie doesn’t bring any originality to the horror-comedy genre. To be honest, there’s not much originality left to bring to the genre, but Slither takes all the usual conventions from those 80’s horror-comedies and gives it a new millenium vibe. The acting by the cast was well-done and showed that they must’ve have fun doing the film. The special effects were done old-school style with nary a CGI-effect to be seen except for a few brief scenes. In the end, Slither was one fun, rollercoaster of a movie that scared the audience into jumping and recoiling in their seats and at the same time making them scream, shout and laugh when doing so. I’ve never had as much fun these last couple years watching a movie like I did with Slither.
