Ideally, when you think about anime, your mind instantly conjures up images of brightly colored characters, big round eyes, and slice-of-life stories. But the truth is that anime is a wide-ranging medium that covers all sorts of content and caters to audiences of all ages. Some of the best anime series ever created are rated R because they have the kind of content and themes that are inappropriate for children. We aren’t talking about shows like Pokémon or Naruto here. These R-rated anime series feature complex plots, psychological depth, violence, and mature visuals.
These stories lie on either side of the anime spectrum, featuring natural horror tales as well as lighthearted fantasies. If you are a true anime fan and are willing to expand your knowledge of the medium, then this list of the best R-rated adult anime ever created is the perfect place to start. But remember, for an anime to be rated R, nothing is off limits. This means here you'll meet morally corrupted heroes, witness the most gruesome of deaths, and slip into fascinating gore scenes.

35 Drifters (2016)
Fans of Hellsing Ultimate would particularly enjoy this series for its tonal similarities. Drifters follows Toyohisa Shimazu, a rearguard soldier who finds himself pulled into a mysterious realm unlike his own, where mystical creatures and fighters believed to be dead reside. After encountering an unlikely band of warriors who share a similar past to Toyohisa, dubbed the "Drifters," he learns of an enemy faction known as the “Ends,” and their plans to take over the world. Joining forces with the other Drifters, Toyohisa tries to fulfill his wartime destiny.
What Makes Drifters So Great?
Under the vision of creator Kouta Hirano, Drifters comes to bold life. There are no restrictions as to what can be achieved in this series. From historical in-jokes to graphic horrors, Hirano's artistic freedom helps showcase every aspect of the medium’s capacity, with plenty of characters ripped from real-world history to enjoy. The series also pulls no punches in portraying heroes and villains as mere humans who reshaped history through their supernatural fights. Blessed with stellar voice work, including English performances by Robert McCollum and Jessie James Grelle, along with audacious battle scenes, the anime is quite unforgettable.
34 Dorohedoro (2020)
Utterly breathtaking in its visuals, Dorohedoro introduces us to a dark and disorderly district named Hole, which is dominated by magic users and sorcerers. Blinded by power, these magic users consider the denizens of Hole as mere insects, and often inflict pain upon them. However, some individuals, like Caiman and Nikaidou, are immune to their wrath. Together, with the assistance of Hole's numerous residents, Caiman and Nikaidou hunt the magic users down, all while attempting to reclaim Caiman's memories in one of the weirdest anime settings to date.
What Makes Dorohedoro So Great?
Adapted from the manga of the same name by Q Hayashida, Dorohedoro is a bleak and gruesome anime series that does absolute justice to its source material. Grappling with themes of violence, free will, and humanity's penchant for cruelty, it douses every episode with a tragic and nihilistic broth that bubbles in visceral fashion. The series is irresistible but not for the fainthearted, with numerous scenes involving elements of body horror and intense violence.
33 Scum's Wish (2017)
High school students Hanabi Yasuraoka and Mugi Awaya pretend to be the perfect couple in front of their peers, and often receive envious jabs from them. The truth, however, is that their relationship is fake. They are just two lonely souls dealing with a deep-rooted fascination with different people. While Hanabi is in love with her homeroom teacher, Mugi cannot take his eyes off the music teacher.
What Makes Scum's Wish So Great?
On the surface, Scum’s Wish may appear to be a tender coming-of-age tale about unrequited love. However, each episode masks more mature themes like the secret yearns of youth, forbidden love, and the loneliness that settles in the soul. The series is crafted with care and nuance, and watching the protagonists navigate their virtues and vices, compassion and hidden pleasures, is both essential and relatable. Scum’s Wish earns its R-rating because of the mature scenes and a bit of fan service.

What Makes Phantom: Requiem for the Phantom So Great?

In his isolation, Satou develops a huge belief in the Nihon Hikkomori Kyokai (N.H.K.), a secret organization in Satou's imagination that promotes societal isolation and paranoia-driven displacement. He crosses paths with a mysterious girl who tries to help cure him of his acute social withdrawal, and together they embark on a quest to confront the truth about the N.H.K.
What Makes Welcome to the N.H.K. So Great?
While its R-rating comes from occasional nudity, the real strength of Welcome to the N.H.K. is in its depiction of mental illness and the habit of dissociation. The show’s overall tone is lighthearted, and it focuses primarily on Satou’s mundane struggles. However, the heavy subject resonates deeply with the audience. Not only does it make you laugh and cry, but the anime also makes you wonder about humanity, addressing a perturbing cultural trend that has only continued to grow since the series originally premiered.

What Makes Soul Eater So Great?
Soul Eater is a shounen anime that combines elements of fantasy, horror, and comedy and turns it into something very wicked and entertaining. The action and the visual flare are the main attractions of the series. However, beneath the fluid and creative animation is genuine character depth and themes of trust and belonging. The reason for its R-rating is its high levels of violence, and the vivid depiction of evil that puts a surreal spell on the viewer.

28 Ergo Proxy (2006)
Ergo Proxy is yet another post-apocalyptic series. It is set in the domed city of Romdo, where humanity has created AutoReivs — androids that help humans in their day-to-day activities. The reason for their creation was a catastrophic event that destroyed the world and made it uninhabitable. However, when these AutoReivs start to contract the “Cogito Virus,” they also begin attaining self-awareness. Re-l Mayer, the granddaughter of Romdo’s ruler, is responsible for investigating this deadly virus. To do so, she ventures outside the dome to deal with strange, artificial creatures.
What Makes Ergo Proxy So Great?
A compelling blend of sci-fi, noir, and gothic, Ergo Proxy is a series that mesmerizes the viewer with its stunning visuals, nerve-wracking themes, and thought-provoking plot. Its dystopian environment outside the sterile and untouchable domed city is what delivers most of the intrigue. Moreover, the anime also comments on a person's consciousness, the limits posed by technology, and our dependence on it.

27 Gantz (2004)
The afterlife is a subject of curiosity. Perhaps one of you has at least once thought about what it is like after you die. But imagine still not being free from the world after leaving everything behind. Imagine entering deadly games run by a mysterious black sphere. Imagine having to literally fight for survival and freedom. That's the premise of Gantz, a fantasy anime that focuses on two friends, Katou and Kurono, who have recently died in a train accident. After their death, they're turned into unwilling warriors and are forced to hunt down aliens, armed with weapons and futuristic equipment.
What Makes Gantz So Great?
Gantz has a provocative premise that entirely converts the sci-fi survival genre into something new. But remember, it is not for the fainthearted. The gritty action, depiction of violence, extreme gore, and black humor shake you to your core. Despite being criticized for some of its visceral scenes, the series balances it by infusing the narrative with thought-provoking questions about conscience and mortality.

In Elfen Lied, the main character is a dangerous mutant humanoid girl named Lucy. Being born with a pair of horns and invisible telekinetic hands, aka "Vectors," Lucy became the subject of experimentation. When she gets a chance, though, she escapes captivity and leaves a lot of blood and devastation in her wake. Moreover, her escape leads to Lucy creating an innocent split personality for herself, where she turns into a child without speech. Two college students accept her into their home, unaware of Lucy's bloody past and the numerous threats closing the distance.
What Makes Elfen Lied So Great?
The anime lasted 13 episodes, but in that short amount of time, fashioned a compelling and memorable story with resonant main characters. Notorious for its graphic violence and mild nudity, the series ultimately showcases two facets of the same narrative — one where Lucy is exploited for her powers, and the other where she is treated with kindness and care.

What Makes Deadman Wonderland So Great?
If you’ve recently watched Squid Game and have enjoyed the sheer ridiculousness of its violence, then Deadman Wonderland is here to take one, no, ten steps further in the direction of dark and delirious.

20 Harem in the Labyrinth of Another World (2022)
Harem in the Labyrinth of Another World follows Michio Kaga, a young man who suddenly finds himself transported to a fantastical game world.

After purchasing a companion in the form of Roxanne, who he quickly grows attached to, he continues to purchase more partners in order to expand his party.
What Makes Harem in the Labyrinth of Another World So Great?
Despite being adventurous and captivating, Harem in the Labyrinth of Another World is an odd isekai anime.

The horror is thankfully balanced with plenty of adult-oriented comedy as well, as its sense of self-awareness opens the door for dozens of ridiculous scenes.
