Next up on our list of best dark anime series is Dororo!

Daigo Kagemitsu is a man in desperate search of endless power and strength. It’s almost as if power is the holy grail.

Soon his burning desire got the better of him as he gave up on Buddha and made a plea with the demons to grant him the power to rule his land and prosper it wealth and growth.

His deal with demons included a sacrifice. The sacrifice was his own newborn son’s limbs, organs, eyes, ears, skin, and senses.

What’s most frightening about this is the fact the boy manages to survive, even after being thrown away in the river by his very own parents.

Fortunately, he was saved by a healer who restored his limbs with prosthetics and gave him powers that rival even the demons themselves.

The boy takes on the name ‘Hyakkimaru’ and travels alongside a young girl named Dororo, killing demons one after the other in a quest to take back what he lost in that wretched sacrifice.

3. Goblin Slayer

Is there really anything more disturbing than a goblin coming to your neighborhood just to wickedly kidnap a bunch of women for the sole of purpose of breeding?

Death notes answers the question of what happens when a human gains the powers of the God of death aka ‘The Grim Reaper’ (Shinigami in Japanese).

One day, a shinigami named Ryuk drops a black book into the human realm. It is then picked up by Light Yagami.

Light could not believe the bizarre rules that the book contained. It essentially enabled anyone to kill another human by simply writing their name (while picturing the person’s face) inside one of the pages of the book.

What’s crueler is the fact that you can write the reason for death as well. Light is now the embodiment of justice by mass-murdering all criminals on sight.

The world’s greatest detective L decides to stop Light because he believes that criminals deserve a second chance and that Light is not the one who should take law upon his own hands.

Shinichi almost loses his human nature and develops a dark side.

15. Higurashi: When They Cry

Higurashi: When They Cry is one of those animes that just love to show lots of terrifying gore content.

16. Taboo Tattoo

Taboo Tattoo is the story of how a boy named Seigi goes around town saving people from gangs and other dangers.

As a token of gratitude, the homeless man rewarded Seigi with a tattoo that contained supernatural powers.

Now a soldier named, Izzy Bluesy, from the American army is back in Japan to collect all the tattoos. She and Seigi engage in lots of fights.

What is dark about this anime is that in the battle to collect these tattoos, many characters lose their limbs as a result. Talk about gore.

17. Psycho Pass

Psycho pass is directed by Gen Urobuchi who is one of the top names when it comes to creating dark and nihilistic anime series.

This anime features a world where each person’s tendency to commit a crime is assigned by a system. An inspector and a hunting dog are set to apprehend a person once their crime coefficient reaches a high level.

By using this “Sibyl system” the government feels the crime frequency will come to a halt.

However, Akane discovers that the system is corrupt and the Sibyl system is incorrect when it makes its predictions.

This is apparent when a crime boss named Shoga is assigned a low crime efficiency even after all the crimes he has committed.

Inspectors like Akane work for the system to ensure that enforcers don’t do anything that goes against the system.

18. Fate Zero

Another masterpiece directed by Urobuchi.

This is a story that features 3 families who get into a war where the victor will be rewarded the ‘Holy Grail’. 

The Holy Grail is a miracle from God that whoever is in the possession of is gifted the ability to grant any wish.

The last 3 Holy Grail Wars did not end in a win for each of the families so it was termed ‘inconclusive’.

And, that’s why the fourth holy grail is about to take place.

There are 7 mages chosen by the families who will fight each other and the last one standing will be hailed as the winner.

Kiritsugu Emiya, a renowned killer of mages is hired by the Einsbern family in the hopes that his skills as a hitman will be enough to get rid of the other mages.

For an anime that was released in 2011, it has stunning animation and particularly decent graphics.

19. The Promised Neverland

Many of you will feel that this is absolutely the darkest anime on this list.

And, the truth is, this anime is one of those rare animes where you desperately want the main characters to survive and if they don’t you would end up crying for days on end.

The Promised Neverland is about three 11-year-olds who live a lavish life inside an orphanage alongside 37 children.

The children are taken care of by Mother Isabella. What everyone believed was that: a child can leave the orphanage only when he/she is ready to be adopted.

However, when Emma and Norman decided to follow one of the children that were sent for adoption, they were shocked beyond belief to see that the child was not really sent to be adopted.

Instead, the child was sent to be eaten by a demon so that it doesn’t turn into a mindless monster…

Talk about a gritty anime…

Kino’s travels is an anime that details to its viewers how merciless and apathetic humans can really be.

What’s more alarming is the fact that Kino never interferes with whatever is going on in front of her eyes.
