Harem in the Labyrinth of Another World  is  r-rated anime series

In 1st episode, he fought with bandits thinking it is just a game but later he found out he cannot log out and he is stuck in this gaming world where things got real.

There is an uncensored adult anime version, and I know you guys will only watch the uncensored one. Because we are same brother we are the same.

9. Skeleton Knight in Another World

Skeleton Knight in Another World r a rated anime tv shows

At the start it makes clear that it is going to be dark gritty r-rated anime, The theme is dark and disturbing

A gamer fell asleep while playing the game and he found himself in the game world as a skeleton when he woke up. He possessed the powerful weapons and armor of his avatar with a skeletal appearance. Now I am not going to talk about this anime because I only watched 3 episodes,

I have mixed feelings about this show, most people think it is a clone of the Overlord, but it is not. In terms of fanservice, I’m not a big fan of assault-style fan service in the name of fan service. But it is worth a try and yes I am going to continue this show.

8. Hellsing Ultimate

Hellsing Ultimate is best r-rated action anime

Man for me Hellsing Ultimate is the best r-rated action anime. If you love dark animation, gore, action, charismatic characters, bombastic plot, and dialogue! Here you are this is the best adult anime for you.

Hellsing is an organization dedicated to destroying these supernatural forces that threaten humanity’s existence. A powerful military is led by Integra Fairbrook Wingates Hellsing, who battles the ghouls, vampires, and mercenaries in an all-out VAR inside the Hellsing estate’s Victorian hallways.
This anime is worth watching.

7. Highschool of the Dead

Highschool of the Dead is r rated anime tv shows

We know Highschool of the Dead is a popular r-rated anime tv show about zombies when suddenly in Japan dead began to rise and the city was in complete chaos.

A group of high school students with the main character named Takashi Kimuro fights these zombies with his friends to survive. As a dark, horror, and creepy theme show, it will surely give you chills at some point, but in order to keep the environment light, it has lots of fan service.

6. Deadman Wonderland

Deadman Wonderland best adult anime

When you think anime can’t get dark and disturbing anymore, then you got Deadman Wonderland. This r-rated anime series may not be for everyone to watch an anime about underage children going to a brutal prison.

The prisoners play life-or-death games or fight one another to the death. It is not suitable for all ages, nor is it recommended for all stomachs.

5. Sekirei

best adult anime

After Deadman Wonderland I do not want to add any other dark gritty anime back to back, so here I give you Sekirei the best adult anime with a harem, romantic comedy, and supernatural elements.

It’s about a 19-year-old boy Minato Sahashi who failed his entrance exams, While returning home a beautiful woman falls from the sky on him, yup from the sky, That woman is a supernatural being known as Sekirei a humanoid being with powers and abilities. Where Minato Sahashi got dragged into the world of the Sekirei and with her have to battle for survival against others called “Sekirei Plan” It’s a fun anime to watch alone.


best r-rated action anime

Gate is about the random opening up of another world in Japan. As supernatural creatures and warriors clad in medieval armor emerge from this gate, they charge through the city, killing and destroying everything in their path.

The story moves toward both sides Japan and the other world calling a truce. Rather than killing each other senselessly. There is no doubt that GATE is violent for kids indeed it is an best r-rated anime series.

3. Btoom!

Btoom! r rated anime tv shows

Btoom! It’s even not my cup of tea.

However, the uncomfortable violence and outrageous scenes make it worth mentioning.
There are some scenes that are too graphic and intense for some people to watch. The theme of this anime is psychological, and survival.

2. God Eater

God Eater best adult anime to watch

In the year 2071, humanity is in danger of extinction following the appearance of man-eating monsters called “Aragami” that are immune to conventional weapons. During their ravaging, they consumed everything in their paths and left nothing behind. A group called Fenrir was formed to fight them with the aid of “God Eaters” in a last-ditch effort to save mankind.

It is a graphically animated action/fantasy series with disturbingly violent scenes.
I found this anime to be one of the most uncomfortable I’ve ever watched, just like Deadman Wonderland.

It’s impressive considering it is only 12 episodes long. As you progress down the line, the violence will make you flinch. For me, it is one of the best r-rated action anime.

1. Redo of Healer

redo of healer uncensored adult anime series

As far as r-rated anime series goes, Redo of Healer is the king.
The anime is far more disturbing, messed up, and believe me when I say it will make you feel disgusted. I personally think that it is one of the most hardcore r-rated anime out there.

This is not to say it’s a bad story, but it’s very heavy and not easily digestible even by adults. This show is sometimes hard to watch and it might be difficult to identify if the protagonist is good or bad. However, it is also true that it is clearly about revenge.

The torture this character undergoes makes it hard not to see some justification for his actions, if not at least some understanding. Be warned this show isn’t for the faint of heart.

10 Best R+ Rated Anime Honorable Mention

I kept it separate because it is very popular among the community, but I wanted to include it in the list since it is trendy among viewers.

1. Chainsaw Man

chainsaw man r+ rated anime

Hold on to your seat for this rated RX anime to blow your mind with its great storyline, action, and character design that gives it a fresh look. The animation is completely on another level, and it’s fantastic. MAPPA really did a great job.

2. Attack on Titan

attack on titan top r rated anime tv series

Yes one of the greatest r+ rated anime of the decades, when ever someone will ask about the best anime series Attack on Titan will be one of them. It didn’t seem to be a big deal to me when I started watching AOT. The kid saw his mother die at a very young age when Titan attacked their town and destroyed everything, almost wiping out the entire town’s population, and he vowed he would kill every titan that had ever existed. It seems like a pretty normal storyline to me.

After season 2, everything changed from killing titans to politics, betrayal, depression, and more… Characters dying in AOT aren’t unusual. Give it a shot if you’re not sure whether to watch it or not, and you’ll love it.

3. Devilman Crybaby

devilman crybaby rated rx anime

Animation is crap! Netflix did a lazy job with the animation, but the storyline was good and the pacing was solid, but it didn’t work for me. That is the reason I am not going to talk much about this anime. There are some who like it and some who don’t, including me. It doesn’t mean Devilman Crybaby is bad, it has a message for its viewers. Give it a try. It is only 10 episodes.

4. Parasyte

parasyte is rating r+ anime

One of my favorite r-18 anime out there, Parasyte is just like MCU’s Venom, parasitic aliens come on earth and take control of the human body by burrowing into their brains. Shinichi Izumi, a 16-year-old high school student, falls victim to one of these parasites, but it does not take over his brain. Instead, it takes over his right hand. Shinichi is the only one who can help Migi survive since the parasite is unable to relocate.

5. Cyberpunk: Edgerunners

cyberpunk edgerunners best r+ rated anime

This is a nice sci-fi r+ rated anime show you can enjoy. The story is intense and filled with action and emotion. The anime is a pulse-racing adrenaline rush combined with emotional moments that had me in tears. Studio Trigger creates incredible animations. A lot of things happen to the main characters that you don’t expect.

I must say that this anime has all the elements of a very good cyberpunk story, which is a unique genre of science fiction.

6. Re:Zero Kara Hajimeru Isekai Seikatsu

r rated anime series

Re: Zero is truly one of the most terrifying and unique isekai r-rated anime series I have seen. First few episodes and you will find them quite boring at first. it is about Subaru Natsuki main character who is suddenly transported to a fantasy world while on his way home from the convenience store. The main selling point is he has the ability to “Return by Death,” which allows him to respawn at a certain point in time after being killed. The series was well-received by viewers and critics alike for its unique plot, well-developed characters, and emotional depth.

7. Prison School

Prison School is one of the gross funniest r-rated anime series out there and I enjoyed it. It is about a group of young men who are enrolled in a prison-themed school, where they must serve out their sentence and reform themselves.

The story centers around Hachimitsu Private Academy, an all-girls school that has recently decided to admit 5 male students for the first time in its history. However they quickly find themselves at the mercy of the school’s strict disciplinary committee, led by the beautiful and sadistic president, Meiko Shiraki. The series is known for its blend of dark comedy, drama, and ecchi elements,

8. Saga of Tanya the Evil

r+ anime series

With world politics, war, and complex characters, this r-rated anime series is known for its dark theme and action-packed battles. It is about a salaryman who is killed by a god-like being called “Being X,” and is then reborn into a fantasy world as a young girl named Tanya Degurechaff. In this new world, Tanya is a brilliant but ruthless military officer who rises through the ranks of the army, using her intelligence and cunning to outmaneuver her enemies. However, she is constantly at odds with Being X, who has a personal vendetta against her and seeks to bring about her downfall.

9. High School DxD

The OG of r-rated ecchi anime series, High School DxD is a top contender. Whenever you walk down the road to perverted ecchi anime, these are the ones you will find there, My journey of watching ecchi anime started with High School DxD. It is about a high school student named Issei who is resurrected as a devil servant after being killed on a date. He joins a devil club at his school and fights against angels and other enemies, while also dealing with romantic conflicts with the other members of the devil club (My man Issei’s life is one every man dreams of). So it is a world where angels, devils, and other supernatural beings exist and often clashes with each other, but we all are going to watch for its fan service.

10. Ajin: Demi-Human

ajin demi-human best r-rated action anime

Ajin is a thrilling r-rated anime series that follows the story of Kei Nagai, a high school student who discovers he is an Ajin, a demi-human with the ability to regenerate and become immortal. As he is hunted by the government and other Ajin, there are compelling characters.

The downside of the show is that animation is crappy and the frame rate is choppy as well. It’s not a visual treat if that is what you are looking for, and it is most CGI animation which is not that bad, you might feel weird at first, but you will get used to it because of its story, which is quite good actually

These are the best r-rated anime series I feel everybody should watch. Thank you for taking the time to read the blog. There will be more blogs coming soon, so stay tuned
