The Scariest Bloody Anime Girl

Set aside the cute and pretty anime girls you are used to, and make way for these terrifying female characters who will give you the absolute creeps and nightmares to keep you awake for weeks on end.


Al Enma – Hell Girl

At first, Ai Enma appears to be a beautiful, harmless young girl with a cold personality, who really doesn’t spark fear. However, she possesses otherworldly powers that will leave anyone terrified.

If someone is looking for vengeance, all they need to do is pull a red string tied around a certain straw doll, and Ai will come and deliver the chosen target to hell. The catch is that the client who pulls the red string needs to agree to travel to hell as well. Many clients choose to back out of this deal once made, but making a deal with Ai is like making a deal with the devil, and she will drag you to hell, no matter what it takes.


Diana and Elaine Reed – Genocyber

Genocyber is famous for being one of the goriest and most controversial anime shows ever made, even though it is fairly old, made back in the ‘90s.

Diana and Elaine might seem like young, innocent twins, but in reality, they are a mix of robot makeup, an animal's nervous system, and wild instinct. They have been created to kill on site, and do so in gory, bloody ways. They are indestructible as well, not even affected when they are the center of a full-blown nuclear attack.

They are what nightmares of made of, innocent children who also happen to be the ultimate machine of vengeance and horror.


Shiro – Deadman Wonderland

Shiro, from Deadman Wonderland, has a deadly split personality. She was a science experiment of Hagire Rinichiro and Sorae Igarashi, who put her through multiple horrible experiments.

Through these experiments, the first Deadman was created, along with Shiro’s second personality, who is known as the Wretched Egg. This second personality is what helps her deal with her torture and pain.

Anyone who comes into contact with Shiro can never be sure which version of her they are meeting, either the sweet, energetic girl or the sadistic and bloodthirsty Red Man. The unpredictability of her character makes for great suspense and a thrilling storyline.


Sachiko Shinozaki – Corpse Party

Sachiko was a reclusive and shy girl when she was alive. After the death of her mother, she transforms into a vengeful and sadistic spirit.

She first appears as a friendly ghost, but soon turns into a bloodthirsty spirit who murders anyone she wants.

What makes her absolutely terrifying is that she doesn’t like to kill her victims straight away, instead, she takes her time by ripping their tongue out and gouging out their eyes, just for her own amusement.

To make her character even more disturbing, she targets children, finding absolute bliss from their torture and deaths.


Shion Sonozaki – Higurashi

When first introduced, Shion seems like your average girl, happy and energetic with a bubbly personality. However, as more truths are revealed about her, everything goes south.

Shion has a terrifying side to her that is difficult to grasp. She has a spectacular mental breakdown that leads to her being responsible for a mass amount of bloodbaths and violence. She is shrewd, manipulative, cold and an absolute delinquent.

Her bubbly, friendly appearance is a complete contrast to her violent, unstable behavior, which definitely does make her unpredictable and totally scary!


Ophelia – Claymore

Ophelia is one of the scariest females you will come across in any anime show.

She absolutely delights in murdering and killing anyone she wishes dead. To add to that, she doesn’t kill them until she has spent her sweet time maiming, torturing and teasing her victims with the idea of death.

Ophelia is incredibly unpredictable, she is wild and has an overwhelmingly sadistic personality. Her elven-like appearance should not throw you off, she is really what nightmares are made of.


Diva – Blood+

Diva is pretty, she comes across as charming thanks to her good looks. However, as pretty as she is, she is so much more dangerous. She is completely unpredictable and can turn in a second.

She was raised in poor conditions, treated badly by those who were supposed to love her. This upbringing is what drove her to be the epitome of evil, and she carries it off flawlessly.

To make her even more frightening, she is really intelligent. She thinks things through and executes her sadistic plans really well.

The Scariest Brutal Gore Anime

Sometimes a little bit of horror and gore can be just what you need to liven up your anime. If you are really looking for something full of brutality, violence, and bloodshed, try and watch one of the below anime.



Even though it was made in the ’90s, Genocyber is one of those gore anime shows that will always be controversial.

It is a mecha horror anime, spread across five seasons, which centers around a new weapon that destroys and kills anything that moves. Other than the plainly horrific gore on screen, this anime did something no anime had done before, it contained scenes of children being blown up and murdered.

Genocyber has enough bloodshed and gore to last you a while and is an anime only to be watched by the brave of heart.


Terra Formars

Terra Formars gained notoriety by being the most censored anime show ever made.

The story is set in the near future. Six crew members travel to mars, but they are met with a horrid surprise. Giant mutant humanoid cockroaches devour them just as they send a transmission back to earth. Back on earth, humanity plans to send an exterminating party to mars to rid it of these mutant creatures.

There is so much censorship in Terra Formars that it is a definite must-see for anyone who has a draw towards all things gore and brutality. It might seem like a simple storyline, but it will leave you with haunted dreams long after you have finished watching.
