Darkness Devil

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

Appearance
The Darkness Devil's appearance is made up of many bodies with two human bodies acting as his legs and three other human bodies acting as his torso and a head akin to that of a pterodactyl with curved horns. One of the human bodies has its arms standing outwards holding out 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 swiftly moves through them and removes their arms. The Doll Devil, through Tolka, offers the Chainsaw Devil's heart in order to gain the power to kill Makima. The Darkness Devil fulfils 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 decapites 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.
