Darkness Devil

The Darkness Devil (の) is a devil that embodies the primal fear of the dark.

It serves as the secondary antagonist of the International Assassins arc.

Appearance
The Darkness Devil's body is made up of many human bodies, with two bodies acting as his legs and four other human bodies acting as his torso, each having a unique face: the one immediately below the neck has no eyes, nose and a vertical mouth, the second head has open eyes and a stitched mouth, the third one has no nose, an open mouth and stitched eyes, and the fourth one has no eyes and a somber expression. Its head akin to that of a pterodactyl with curved horns. The first human body has its arms stretching outwards holding what seems to be a cape of darkness.

Personality
Nothing is currently known about the Darkness Devil's personality except that it will attack anything it perceives as a threat.

International Assassins arc
The Darkness Devil makes its first appearance when Denji along with several other Devil Hunters and assassins are transported to Hell by the Hell Devil. It emerges out of a door in the sky and approaches the recently transported people. Some of the fighters there brace to meet it but it removes their arms through a surreal magic power that croaks like a frog. The Doll Devil, through Tolka, offers the Chainsaw Devil's heart in order to gain the power to kill Makima. The Darkness Devil fulfills the request by granting a piece of its body to Tolka's master on Earth which she swallows.

With the contract complete, the Darkness Devil picks up Tolka and decapitates him. Kusakabe draws a circle on the ground using his blood and tries to use the Stone Devil against the Darkness Devil, however the Darkness Devil catches it out of the air with ease and shatters it which shatters Kusakabe in turn. Beam attempts to revive Denji by giving him some of his blood and pulling his chainsaw cord, and the Darkness Devil slices Beam into multiple pieces by pointing at him.

Quanxi and Tamaoki charge at the Darkness Devil simultaneously and try to kick it but the Darkness Devil swiftly scythes through them both, catching Long, Pingtsi and Power in the aftermath of its attack as well. The Violence Fiend, who has had his mask removed by Kobeni Higashiyama, leaps in from above to try and kick the Darkness Devil but the Darkness Devil speaks a word and pierces the Violence Fiend multiple times. Denji leaps in off of the Violence Fiends' back and tries to attack the Darkness Devil with his chainsaw arm unsuccessfully.

The Darkness Devil clasps his hands together and Denji's body contorts painfully, disabling him. The Violence Fiend leaps in once more desparately with his severed arm held in his mouth but the Darkness Devil summons a black blade which pierces the Violence Fiend and stops his attack in its tracks. It then kneels down over Aki Hayakawa and looks at him.

The Darkness Devil looks at the Angel Devil and causes both him and Aki to start bleeding severely. Just as it reaches down to grab Aki, the Prinz emerges from the ground nearby and tries attacking the Darkness Devil. A frog ribbits nearby and Prinz is thrust back, losing several of her limbs in the process. Makima instructs Prinz to summon her to Hell and she faces off against the Darkness Devil.

The two of them point at each other; Makima's finger breaks and the Darkness Devil begins to bleed and stoops over. Makima makes her way over to Tolka's body and the Darkness Devil clasps its hands together, breaking Makima's entire arm. As Makima uses Tolka's body as a medium to summon the Hell Devil, the Darkness Devil conjures its black blade once more and pierces Makima with it just as everyone is transported back to the department store.

Abilities
The Darkness Devil is described as being a transcendent being; one of the devils embodying a primal fear and has never experienced death due to being so powerful. As a devil that embodies a primal fear, it can be assumed that the Darkness Devil is almost as old as humanity itself. The Darkness Devil possesses all of the standard devil abilities such as blood consumption, contract creation etc. The only contract with it seen so far is with Santa Claus, in exchange for bringing the heart of Denji to Hell, Santa Claus gained a small portion of the devils flesh which allowed the assassin to manipulate their body in darkness and amplifies their total power. This indicates that even a small portion of its flesh contains immense levels of power.

Physical Abilities

 * Immense Speed: The Darkness Devil can travel and attack at high speeds. It was able to appear in the midst of several devil hunters, including Quanxi without any of them being able to perceive its movements. By using its multiple arms it could slice through several fighters before they could react.


 * Immense Strength: The Darkness Devil has shown to be able to lift its targets with great ease and damage them easily by swinging its arms around.

Devil Powers

 * Darkness Manipulation: As the embodiment of fear of darkness, the Darkness Devil has the ability to manipulate darkness. It can transform into a mass of darkness and envelop the surrounding area in darkness, manifesting the bodies of several bisected astronauts as it does so.
 * Blade of Darkness: The Darkness Devil can also conjure a jet black blade of darkness with bells attached to it's hilt that can be telekinetically controlled to attack its enemies. Once it makes contact, any being hit by it will hemorrhage violently once the bells ring.


 * Force Manipulation: The Darkness Devil has been shown to offensively manipulate an invisible force in a variety of way similar to Control Devil. Once the Darkness Devil stares directly at another being, be it devil or human, they will begin to hemorrhage immense amounts of blood until death. It can also inflict damage to targets it points at with its index finger, however it is shown that Makima is stronger in this ability as she could heavily damage Darkness Devil while it can only damage Makima's fingers at best. It seems like the ability's potency can be increased by changing gesture, as Darkness Devil completely twisted Makima's arm in the second attempt by praying with two of it's hands despite the Control Devil also tried to block the attack with all five fingers. The Darkness Devil can also sever the arms of several humans, fiends and devils, brutally obliterate their body using invisible force by chanting an unreadable word with seemingly no physical effort.
