War Devil

Lore & Background

Yoru's existence is defined by her contract with Asa Mitaka, whom she resurrects as a Fiend. The War Devil's primary motivation stems from the fact that the Chainsaw Devil nearly destroyed her in the past, erasing her concept and causing her to seek revenge. This drive leads Yoru to manipulate various characters, including Fami (who claims to be the Famine Devil) and Barem Bridge of the Chainsaw Man Church. The War Devil's power grows as humanity's fear of war increases, allowing her to offer deals that leverage this fear. For instance, she proposes a deal where Denji must defeat the Death Devil to earn Asa's affection, or face transformation herself.

In Their Own Story

After Barem Bridge destroys Denji's home and kills his pets, leading to Nayuta's apparent sacrifice, Yoru capitalizes on the chaos. She offers Denji a new deal: defeat the Death Devil and gain Asa's affection, or be transformed. The pair then clash with the Falling Devil, which Yoru defeats after America reinvents the nuclear bomb. Although Denji is left for dead, Fami saves him, revealing herself as Li'l D, the Death Devil. Li'l D explains that Yoru intends to cause an infinite war by having Pochita erase death. In a climactic confrontation, Barem appears, and an enraged Denji gives Pochita control to devour him. Asa decides to sacrifice herself to allow Denji to kill Yoru, but Pochita instead devours Li'l D. Yoru seemingly kills Pochita, only for Denji to emerge in a new hybrid form and defeat her.

Reader's Guide

The War Devil's influence is deeply intertwined with the narrative of Chainsaw Man, particularly in its second arc. Key moments include the contract with Asa Mitaka, the manipulation of events by Fami (the Death Devil), and the eventual confrontation between Denji, Pochita, and Yoru. The War Devil's power is closely linked to the fear of war among humanity, which allows her to grow stronger and manipulate others. Her ultimate goal is to revive the Nuclear Weapons Devil and cause an infinite war, a plan that is thwarted by Denji and Asa's actions.
