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!

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

5. March Comes in Like a Lion

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.

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