When you hear “top 10 most” disturbing anime, you probably picture over‑the‑top gore, twisted romance, or bizarre premises that make you squirm. Since the 1980s, Western commentators have often dismissed Japanese animation as weird, violent, or outright kinky – but the reality is far more nuanced. In recent years, some creators have leaned so hard into shock value that the line between daring storytelling and outright exploitation blurs. Below, we count down the ten most unsettling popular series that have sparked controversy, provoked debate, and left viewers both horrified and fascinated.
Why These Are the Top 10 Most Disturbing Shows
10 Goblin Slayer
Debuting in 2018, this dark fantasy series wasted no time courting controversy. The opening episode follows a party of adventurers intent on hunting goblins, only for the creatures to outwit them. The expedition ends in carnage, and a female party member suffers a brutal rape, setting a grim tone that many felt was gratuitously graphic.
Goblin Slayer stands out because its horror is overt and deliberate. While the rest of the series leans toward typical fantasy action, this opening sequence uses shock for maximum impact, turning the show into a cautionary example of how far a series can push boundaries for attention.
9 Interspecies Reviewers
Marketed as a light‑hearted comedy, the series follows a group of adventurers who hop from brothel to brothel to rank the sexual services offered by various fantasy races – from fairies to succubi. The premise itself is risqué, but the execution pushed the envelope even further.
American platforms Funimation and Amazon Prime were caught off‑guard, and by the third episode the screen was blacked out with a censor bar as gender‑bending scenes became explicit. Both Japanese and international broadcasters eventually pulled the series, which only fueled a surge in online curiosity about the censored content.
8 Jungle Emperor Leo
Known in the West as Kimba the White Lion, this 1966 series was a pioneering color broadcast on CBS and was created by Osamu Tezuka, the “father of anime.” While often remembered for its influence on later works like The Lion King, the show also harbors a surprisingly dark episode.
In “Too Many Elephants,” Kimba discovers that a herd of aggressive elephants is slated for extermination. After being rebuffed and beaten by the herd’s leader, Kimba decides to rescue only a single infant elephant and its mother, allowing the rest to be herded into a canyon by tanks and a helicopter. The episode’s bleak moral – “I wish the elephants weren’t so mean, then they wouldn’t have been exterminated” – feels eerily reminiscent of modern creepypasta narratives.
7 Kanokon
The 2008 high‑school romance centers on Kouta, a prepubescent boy, and his two supernatural suitors: a fox spirit and a wolf spirit. While the premise sounds whimsical, the series delves into unsettling territory.
Chizuru, the fox spirit, is drawn as an adult female, yet Kouta is rendered with childlike proportions. Throughout the series, Chizuru repeatedly attempts to coerce Kouta into sexual acts, and Kouta’s resistance – voiced by a child‑sounding English dub actor – emphasizes the disquieting power imbalance.
6 My First Girlfriend Is a Gal
This 2017 comedy follows Junichi Hashiba, a shy teenager who musters the courage to ask a fashionable “gal” to be his girlfriend. While the romance itself is relatively innocuous, the series harbors a deeply disturbing subplot.
Junichi’s friend Minoru is portrayed as an outright pedophile, delivering jokes about a freshman he calls a “granny” and engaging in predatory conversations with children. Despite these unsettling scenes, Minoru is treated as a comedic sidekick and even heroically saves a little girl in the finale.
5 Manyuu Hikenchou
Set in an alternate Japan where a woman’s breast size determines her social standing, this samurai spoof introduces the Manyuu clan, who wield a magical technique to remove breasts from low‑born women. Protagonist Chifusa Manyuu rebels against her clan, using a secret method to absorb other women’s breasts.
The series escalates from fetishistic humor to outright horror in episode five, where Chifusa and her friend Kaede encounter a group of orphaned children who, after misinterpreting Chifusa’s speech, overrun her and begin suckling her nipples, eliciting audible pleasure noises – a scene that even the most boundary‑pushing comedies shy away from.
4 Seikon no Qwaser
Premiering in 2010, this series follows “Qwasers” – alchemists who harvest magical power called “soma” by suckling women’s breasts. The premise alone resulted in heavy censorship during its Japanese broadcast.
The most unsettling character is Katerina “Katya” Kurae, an antagonist who draws power from numerous women, both consensually and non‑consensually. Designed to appear severely underage, Katya also maintains an S&M relationship with her assistant, adding layers of exploitation to an already contentious premise.
3 Eromanga Sensei
On the surface, this 2019 series appears sweet and domestic: a 15‑year‑old manga artist lives with his 12‑year‑old shut‑in half‑sister, who secretly writes his most popular comics. The series adopts a cutesy aesthetic that masks a darker undercurrent.
As the story progresses, the siblings display clear sexual interest in each other, flirting in ways that appeal to audiences craving taboo incest and underage romance. Although the pair never physically consummate, the implication is unmistakable, providing a veneer of plausible deniability while still courting controversy.
2 Loveless
Set in 2005, this twelve‑episode series follows twelve‑year‑old transfer student Ritsuka Aoyagi, who investigates his brother’s murder. In this world, virgins sport cat ears, and Ritsuka’s ears disappear after forming a bond with Soubi Agatsuma, a twenty‑year‑old who was close to Ritsuka’s brother.
While the show includes plenty of action, the central relationship between a pre‑teen and an adult male is its most unsettling element. Critics have labeled it the worst same‑sex anime, highlighting the discomfort generated by the age disparity and power dynamics.
1 Our Maid Is Way Too Annoying
This 2018 series stars Kamoi Tsubame, a muscular former special‑forces operative turned personal maid for a young girl, Misha Takanashi. Though Tsubame isn’t overtly a predator, her dialogue reveals unsettling attitudes: she admits she loses interest in women once they begin menstruating.
In one scene, after touching Misha, Tsubame gazes at the girl’s hand, sniffs it, and delights in dressing Misha in various outfits, creating an uncomfortable visual for viewers. Despite the overtly odd premise, the show lasted only a single season, perhaps indicating that audiences are not rewarding such extreme boundary‑pushing.
Top 10 Best Written Anime
About The Author: Dustin Koski collaborated with fellow contributor Jonathan “Bogleech” Wojcik to write Return of the Living, a novel where a ghost witnesses the first living being after centuries of Earth’s lifelessness. It would make a surprisingly undisturbing anime.
