Nightjar and Asa

Still hemorrhaging, Yoru manages a faint laugh at the sight of a pair of birds in flight. Asa, thrown by the mercy shown to the dove, asks why Yoru bothered keeping her alive when she could have claimed both body and mind outright. Spotting Denji dragging himself toward them, Yoru tells Asa that hijacking a bird's body in the beginning had been a matter of survival. Small as the creature was, she still carried the weight of its guilt over snatching and eating worms.

That guilt, she explains, is what lets her shape sturdier weapons when she takes it on. She tried to grasp Asa's own guilt as well, yet confesses she never managed it. As Asa sits in stunned silence, Yoru declares that whatever counts as sin to her means nothing through a Devil's eyes, right as Denji at last reaches the two of them. Ripping open one of his surviving arms, Denji gives Yoru his blood so she can regenerate, then crumples. Stunned by what he has done, the War Devil revives and presses him on the reason for handing over his blood when she could so easily have killed him. Denji explains that he abruptly recalled her pledge to sleep with him if he devoured a dangerous Devil. Yoru breaks into wild laughter while the world keeps unravelling around them.

Yoru reveals to Asa that possessing a bird at the start was a survival measure and that absorbing guilt strengthens her weapons, though she could never comprehend Asa's guilt. She concludes that her sins are trivial to a Devil. Denji arrives, tears open an arm, and feeds Yoru his blood to heal her before collapsing. When she demands an explanation, he cites her promise of sex for eating a dangerous Devil, sending her into hysterics.

A Volume 24 entry in the War Devil arc, this chapter deepens the bond between Yoru and Denji and clarifies how the War Devil's guilt fuels her weaponry. Death Devil is referenced, and the scene leaves Asa, Yoru, and Denji together as the surrounding chaos intensifies.
