The Darkness Devil appears shortly after 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 immediately attacks, removing all of the group's arms. The Doll Devil, through Tolka, offers the Chainsaw Devil's heart in order to gain the power to kill Makima. The Darkness Devil fulfills its end of the request by feeding a piece of its flesh to Santa Clause on Earth.

With the contract complete, the Darkness Devil picks up Tolka and decapitates him. Kusakabe tries to use the Stone Devil against the Darkness Devil, but is killed with the Stone Devil when the former seizes and destroys it. Beam successfully revives Denji by giving him his blood and pulling his chainsaw cord, but is sliced into pieces by the Darkness Devil.

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 is pierced multiple times. Denji leaps in and unsuccessfully attacks the Devil with a chainsaw arm.

Denji attacks Darkness Devil while enigmatic figures in the darkness are shown.

The Darkness Devil clasps its hands together and Denji's body contorts painfully, disabling him. The Violence Fiend leaps in once more desperately with his severed arm held in his mouth, but the Darkness Devil summons a black blade which pierces the Violence Fiend and completely destroys his body. 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, Princi emerges from the ground nearby and unsuccessfully attacks the Darkness Devil, losing several of her limbs in the process. Makima instructs Princi 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. As Makima's arm contorts and breaks, she offers Tolka's body to Hell Devil in return for bringing them back to Earth. The Darkness Devil conjures its black blade once more and pierces Makima with it just as everyone is transported back to the department store.
