People often mention that some anime series are not meant for teenagers. While it is true, there is also a genre only meant for the mature audience.

Yes, we’re referring to the ‘Seinen’ genre.

Even if you have seen countless thriller, dark, and psychological-themed anime, these Seinen anime series stand apart from those.

In this article, we’ll present you with 26 Seinen titles that cover:

  • action
  • sci-fi
  • fantasy
  • romance
  • comedy
  • mystery

and a lot more genres.

So, grab your popcorn along with a few tissues just in case, and here we go!


1. Monster


If ‘Monster’ isn’t the best seinen anime out there, I don’t know what is.

It is a keen mix of thrill and psychological genres. Once in a while, people need to consider watching these underrated masterpieces!

Dr Kenzo Tenma is a renowned neurosurgeon and respected well by his superiors and colleagues. When he prioritizes a boy’s life over the mayor’s, resulting in his death, his life shatters. 


2. Parasyte


In my opinion, Parasyte is still underrated even though it gets a lot of recognition. With such an captivating concept, it executes every aspect flawlessly.

It also helps you learn a few life lessons (which we appreciate a lot) such as Mother’s love. 

When Parasytes (worm-like aliens) invade earth and take over humans as their hosts, one of them fails and ends up taking over Izumi Shinichi’s right hand.

Now he has to confront these parasites in his daily life while he prefers to lead a normal life.


3. Ping Pong The Animation

There are a few anime series out there that teach us real-life values and Ping Pong The Animation is one of them.

It shows what an anime can achieve in just 13 episodes and never lets you take a break-even in the middle of the episodes. 

The story follows two childhood friends “Peco” and “Smile” who play table tennis in their inter-high school and eventually find out what drives them to love this game so much. 


4. Grand Blue

Grand Blue

Grand Blue is one of the best comedy anime out there but with a mature storyline.

With tons of hilarious moments, it takes you on a whimsical journey. You can try watching this if you’re into seinen anime with a comedy approach.

5. March Comes in Like a Lion

March Comes in Like a Lion

We rarely see ‘Slice of Life’ and ‘Seinen’ genres mixed, and this anime displays a strong emotional resonance.

While the first season has been delightful, the second season is one of the most highly rated in MyAnimeList. 

17-year-old Rei Kiriyama is a professional Shogi player who moved to Tokyo to seek freedom from his tense life.

When Rei visits his grandfathers’ wagashi shop, there he meets a trio of sisters.

6. Vinland Saga

After Wit studio’s incredible work with Attack on Titan, we thought it might be hard to get a similar one (animation-wise).

But… with Vinland Saga, we got one amazing piece of work with a perfect blend of action, adventure, and historical themes. 

Thorfinn grew up listening to the stories about Vinland, a place where there is no need for wars.

9. Mushi-Shi

Mushi Shi

If you’re thinking of watching this anime in one go, you might as well skip it.

It is a slow burn yet refreshing story that can brighten up your mood. Every episode brings the inner-beauty of the anime, and I’m sure you’ll love it.

Make sure to take some deep breaths in the middle of every episode because the one we have here is the anime Rainbow.

Within a few months, they need to pull this impossible stunt.


16. Berserk


Berserk is one of the greatest manga of all time, and so is this anime. While manga is a lot better and I prefer it over anime, I’d still say it is a pretty good adaptation apart from the 2nd season. 

A young mercenary born from the corpse of his mother enters the battlefield at a very young age and puts his life on the line to survive.

Later on, he joins “White Hawk,” and slowly climbs up the ranks only to find out that the world isn’t as good as he thought. 


17. Saint Young Man

Saint Young Man is a seinen anime consisting of only 2 OVA episodes but you can enjoy every minute of it.
