8. 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.

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. 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.

15. Redo of Healer (2021)

redo of healer uncensored adult anime series

As far as r-rated anime series go, 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.

  • Plot: Healer travels back in time to take revenge
  • Theme: Fantasy, psychological, adult
  • Rating: R+

Looking for a hilarious isekai parody anime? Then you need The Eminence in Shadow in your life! Our boy Cid gets reborn into a fantasy world and instead of being OP, he decides to pretend to be OP by creating an entire secret society around himself.

He acts like the ominous mastermind behind everything, when really he’s just a goofy chuuni putting on an act. Watching Cid ham it up as “Shadow” while his comrades take his ramblings seriously is comedy gold.

With its satire of overpowered MCs and secret organizations, Eminence in Shadow is a side-splittingly funny adult anime you gotta watch!

  • Rating: R+

7. Attack on Titan

attack on titan top r rated anime tv series

Yes one of the greatest r rated anime of the decades, If someone asks 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.

  • Rating: R

Blast into outer space for some intergalactic war drama with Legend of the Galactic Heroes: Die Neue These! It’s like Star Wars for adults but with fewer lightsabers, and more calculations.

Reinhard and Yang are rival geniuses battling to dominate the galaxy with their massive spaceship armadas. But these boys are more into witty banter and 4D chess than pew pew pew space fights. Though with names like Bloody Marquess, you know stuff eventually goes down!

Follow these cerebral badasses as they wage tactical and philosophical war for the fate of the cosmos. It’s a thinking geek’s adult anime classic overflowing with sci-fi intensity and mecha models.

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.

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.

prison school r rated anime series

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.

15. 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

  • Plot: Boy discovers he’s immortal demi-human hunted by government
  • Theme: Action, horror, supernatural
