highlights from top 10 dementia anime

When it comes to anime, the term ‘Dementia’ does not mean the actual disease. Dementia animes are those that can mess up your mind with their absolute madness and thrilling plotlines.

Things can get pretty ugly, pretty fast and that’s the excitement you get when you watch these animes. If you are not into the dark-themed show then, I’d suggest you leave this page.

So, without further ado, here is the list of 10 Wicked Dementia Anime that you won’t forget for a long long time.

10. Popee the, Performer

  • Logline: Daily life of a clown and his crewmates in a circus.
  • Year: 2001
  • Genre: Comedy
  • Studio: Nippon Animation
Popee the Performer

Popee the, Performer is a slapstick series. It revolves around a clown working in a circus and carries a baggage of emotions that leads to mad actions that can even hurt someone. But this dementia anime tries to focus more on comedy than the darker side. So if you wish to watch this show, you can give it a try.


This wonderfully written series revolves around circus rehearsals of Popee and other characters. Each time they try to attempt an act, they fail and, this creates a cycle of loads of laughter. Popee who is the star performer is an old clown.

He wears an odd red-stripped jumpsuit and bunny ears. The driving force of the whole series is the nuisance created by this clown.

9. Mawaru Penguindrum

  • Logline: A quest of two brothers fighting hard to save their little sister’s life.
  • Year: 2011
  • Genre: Supernatural
  • Studio: Brain’s Base
Mawaru Penguindrum

“Family is a life jacket in the stormy sea of life”. This quote fits perfectly on this next dementia anime series. No matter what family will always stand you is the one way to describe this show. Incidentally, I also watched this with my sibling and we were both riled up. I hope you will give it a shot as well.


This series is about the Takakura family. Following the loss of their parents, twin brothers Kanba and Shouma live alone with their sister Himari. She was admitted to a hospital due to her poor health.

One day the twins decided to take their little sister to the aquarium. Little did they know that her health will further deteriorate. Fortunately, Himari is saved miraculously by mysterious penguins who in return for her life demand that the twin brothers complete a dangerous job for them.

8. Neon Genesis Evangelion

  • Logline: In the war between humans and monsters who will win?
  • Year: 1995
  • Genre: Psychological, Drama
  • Studio: Gainax

If you are looking for an anime that can make you jump on the edge of your seat, then I’ll highly recommend you to watch this dementia anime. It has got everything from giant fighting robots, gripping stories, and mind-numbing plot twists. Despite being so much going on in the show, it never drifts away from the end goal of the story. 


The world is under a grave threat from giant monsters and humanity is on the verge of extinction. Shinji Ikari is an ordinary boy who was abandoned by his father. Years later he is called up by his father to join a team of paramilitary forces called the NERV and protect the planet. 

7. Yamishibai: Japanese Ghost Tales

  • Logline: A set of horror Japanese folklore.
  • Year: 2013
  • Genre: Folklore
  • Studio: ILCA
Yamishibai Japanese Ghost Tales

After watching Yamishibai, you will start recalling those horror stories that your grandparents, parents, or friends told you. This series consists of various Japanese folklore that I am sure you might not have heard of. These are terrifying tales complied in this one dementia anime and I recommend you watch it with someone by your side.


The first season of the Yamishibai series is narrator by an old man who sits at a children’s park. He is not an ordinary storyteller.

With the help of a device, kamishibai(a traditional paper-scrolling device)he tells children horror stories. Those chirpy little kids love the way he recites the story. The curiosity that this simple, yet fearful anime series create is unimaginable.


  • Logline: Naota’s life takes a drastic turn when he comes across a psychopath chick.
  • Year: 2000
  • Genre: Comedy
  • Studio: Gainax
FLCL Anime

FLCL is one of the very few dementia anime that incorporates comedy in its plots and is able to do it so successfully that it plays with your mind. The only thing that I found negative about this anime was its episode count which was barely six. 


Naota Nandaba is a high school kid who lives a very simple life until one fine day when a psycho chick named Haruko Haruhara hits him with her Vespa. Not only that she also drags Naota into a supernatural battle that threatens both of their lives.

  • Studio: Madhouse
Mousou Dairinin

If I say that the main villain/hero of this dementia anime is an elementary kid, would you watch it? Though not exactly evil, you will come to know why our protagonist does bad things as you watch it. The story is smartly crafted and tests the power of your brain many times.


Tsukiko Sagi is a designer. She is shy and has no record of any enmity. One night as she walking towards her house she is suddenly attacked by an elementary school kid.

For further investigation police detectives, Keiichi Ikari and Mitsuhiro Maniwa are given the responsibility. They think that Tsukiko is lying. Until one day when the news of the second attack comes to light. I will write no further about it and leave you in suspense.

Boogiepop Phantom

Boogiepop Phantom is an anime series based on the Boogiepop light series novel. This mind-boggling dementia anime is packed with twists and turns that are simply phenomenal to watch. The presentation of the series is also highly applaudable.


Boogiepop (who is said to be an incarnation of death) is a famous urban legend. Five years after gruesome murders in an unnamed city of Japan, the disappearance of high school students has left people in shock and despair.

All the fingers are pointing towards Boogiepop. Some people believe these stories. Others laugh as believing in some age-old legend’s return is hard to believe. But if not Boogiepop, then who is behind these disappearances?
