How do you define 22+ anime series?
- By their tag? Some anime in the 13+ range seem too mature for their rating.
- By how explicit they are? This one is more accurate.
- By their violence? This one is definitely justified.
- Or their deep psychological traits? (Mental illness, etc).
No matter how you look at it, some anime are deep, graphic, obscene or a step away from being classified as Hentai.
Usually when they’re too Ecchi like Prison School.
Yet some anime get away with safe ratings like 13+ (Food Wars).
So in this post, 18+ relates to profanity, nudity, strong themes and violence.
Here are some anime that match that description…
18+ Mature Anime Series List:
1. Haganai: I Don’t Have Many Friends
Haganai is a rare series of its kind. I mean, how many slice of life have nudity, and extreme profanity?
The story is about making friends and dealing with loneliness. But what they get up to is in the realm of Ecchi/wtf did I just see.
NOT for kids.
2. Food Wars
That’s right, this is a food/Ecchi series with plenty of “almost naked” scenes and obscene animation.
And Food Wars isn’t shy about its fan service either. Seeing as you see both boys AND girls in the flesh (almost).
13+ is too generous for a rating.
4. Owari No Seraph
Owari No Seraph is one of the rare demon/monster anime that’s actually good. Like Attack on Titan, the first episode squeezes the emotions right out of your body. And hooks you in.
And what follows from there is NOT at all for little kids.
5. Kabaneri Of The Iron Fortress
Like Owari No Seraph and AOT, Kabaneri is a supernatural anime. Focusing on humans vs monsters (basically).
It’s nothing new, but how it handles itself is impressive. And the gore is ruthless.
That shouldn’t surprise you once you realize AOT shares the same anime studio as Kabaneri.
6. Chrono Crusade
Chrono Crusade, made back in the 2000’s, is a religious/demon anime with a deeper meaning under the surface.
Once you get into it you start to see why it’s not for kids. Both from a violence point of view, and a psychological perspective. As it’s deep, thought-provoking and merciless.
7. Shikabane Hime: Aka
Shikabane Hime is about Makina Hoshimura. Who’s nicknamed “corpse princess” because she’s dead but alive.
The themes, atmosphere and characters are dark by nature. So if you’re expecting all that “hero of justice” stuff you won’t find it here. With the exception of one character who’s caught up in the middle of the madness.
8. Attack On Titan
Attack on Titan goes without saying.
The first episode is horrifying. And the soul crushing violence is enough to scare off any kid who dares to watch it.
It might be over the top sometimes, but that doesn’t make it anymore cuter than it is.
9. Full Metal Panic
Full Metal Panic is one of the classic Mecha shows in animes history. With a new season airing now in 2018.
The anime starts off slow, and so does the violence and cruelty. But it’s there, and it’s uncomfortable to watch. Especially once you start getting into the second season of FMP.
That’s when things get really messed up.
10. Code Geass
Does this even need an introduction?
Code Geass starts off with a ruthless introduction to the story. And that’s NOTHING in comparison to what the chefs of despair are waiting to serve you.
It’s bitter, disgusting, crude, unethical and tasty all at the same time. And you’ll have a love-hate relationship the longer you get to taste what each episode has to offer.
Witchblade is too mature for more reasons than violence. It’s also pretty Ecchi too.
Think of an anime like Kill La Kill, or even Darling In The Franxx. And then add a higher level of violence to the mix. And you basically have Witchblade as the outcome.
It’s forgotten in 2018, but I’d recommend it if you want something different.
12. Eureka Seven
On the surface this anime is all the way Mecha. Plus romance is a consistent theme running throughout this series.
But once you gain some traction and get a little deeper, you start to understand something else.
And that something is:
- Eureka Seven is surprisingly violent.
- It goes deeper than most shows of its kind, and makes you ask yourself all sorts of questions.
- And the 13+ rating given to this show is misleading.
I wouldn’t even recommend this for a 13 year old. Never mind little kids. It’s too deep (but that’s why it’s one of my favorites).
13. Elfen Lied
Want to see a dog get tortured, beaten to death, while the culprits laugh as if they’ve just finished watching a comedy show?
This isn’t even a tip of the ice bergs toe nails when it comes to what Elfen Lied has in store for you.
It’s a sad show, and it’ll make you think about how disgusting some human beings can truly be.
14. Bungou Stray Dogs
One thing I’ll say about Bungou Stray Dogs is: it’s weird!
Tons of the characters are either freaks, eccentrics, weirdo’s or mysterious. There’s something to be said about the level of violence and depth to parts of the story too.
NOT for kids!
15. Fate Apocrypha
If you’ve watched any Fate series, you know how violent they are (Fate Stay Night excluded).
Fate Apocrypha is the latest series in the world of Fate. And like Fate Zero, it doesn’t hold back. So expect to see be-headings, hard to swallow episodes, and some depth to make it all interesting.
16. Fullmetal Alchemist: Brotherhood
Fullmetal Alchemist is a lesson in self-control. When you lose self-control, you do stupid sh** that’ll put you in harm’s way.
The anime shoves this truth down your throat the first few episodes. And later as the story gets deeper, you start to see the dark side of the Military, human struggles and similar themes too mature for little kids.
Btoom! isn’t a favorite. I don’t even like it. BUT the uncomfortable violence and outrageous scenes make it worth mentioning.
Some scenes are too graphic and intense to be watching with little kids. It would be wrong to suggest otherwise.
18. God Eater
Graphical action/fantasy anime with disturbingly violent scenes showcased in CGI animation.
Of all the 18+ anime I’ve watched, God Eater is hands down one of the more uncomfortable shows to watch. Which is surprising considering it’s only 12+ episodes long.
Danganronpa isn’t 18+ for its bloodshed or senseless violence.
No, it’s the psychological elements that makes Danganronpa too mature for little kids.
The anime takes pleasure in trapping unsuspecting kids in a prison-like-school, and then forcing them to fight for their lives to survive.
And in the process you witness the psychological breakdowns of more than a few characters. With death being their final destination.
20. Black Lagoon
This gangster-like anime series goes without saying. It’s gritty, dark, and bred straight from the gutter.
Even the main character is literally born and bred in the gutter of New York City.
If diving into the depths of darkness makes you curious, Black Lagoon won’t disappoint. And it looks good doing it.
This anime will teach you about the dark underworld of an arms dealer, a person who funds wars for a living.
And it’s a realistic representation of what happens in real life. Making the experience of Jormungand even more depressing.
If you want a more “realistic” representation of the underworld, watch Jormungand. It takes it a step further than Black Lagoon, but they’re both still unique in their own way.
Gantz is even worse than Haganai: I Don’t have Many Friends for its profanity.
In fact it’s even worse than Black Lagoon (or on par) for its foul language.
It’s not the most loved series, but it’s dark enough and too cutthroat for little kids to be watching it.
- Tokyo Ghoul.
- Future Diary.
- Akame Ga Kill.
- Taboo Tattoo.
- Prison School.
- School Live.
- Higurashi: When They Cry.

The 1st anime I watched was Dragon Ball Z. Followed by Claymore, Inuyasha, Attack On Titan, and the rest as they say is “history”.
