Official Description
''Sometime after leaving the Public Safety, Denji has now started to go to high school, while he also continues to exterminate devils. He still wishes to get a girlfriend and often tries to "accidentally" expose his identity as Chainsaw Man. Meanwhile, the War Devil returns to the world seeking revenge against the Chainsaw Devil. It possesses a loner high school girl, Asa Mitaka, who goes to the same school as Denji and makes her search for the Chainsaw Man's true identity.''

Enter: The War Devil
Asa Mitaka, a high school girl who doesn't fit in, is accidentally killed after angering the Justice Devil. Her life is saved by the likes of the War Devil, who takes over her body in exchange for extending her life. The War Devil's goal is to wage war on the Chainsaw Man and make him puke up nuclear weapons again.

Asa and the War Devil are now in a contract with each other, with the War Devil occupying part of Asa's mind, and is able to control her at will during certain times. The War Devil tells Asa that in order to destroy the Chainsaw Man they have to get close to him first, and the way to do that lies within finding him at the school he attends.

At the school, the two of them meet Hirofumi Yoshida, who just transferred in. He tells them of the rumor that the Chainsaw Man has enrolled in the Devil Hunter's Club, which entices the War Devil to join as well.

At the Devil Hunter's Club, Asa meets a girl named Yuko who is also a social outcast. The two of them become friends, and the War Devil tells Asa to kill her to turn her into a weapon, as the more she cares about something the stronger the weapon will become. Tired of just being called the "War Devil," it tells Asa to begin referring to it as "Yoru."

Later, the two girls are walking when the reborn Bat Devil crashes through the building, but it is ultimately killed before Yuko or Asa could get hurt, as Chainsaw Man is engaged in a battle with the Cockroach Devil already, and it gets caught in the crossfire.

After the dust has settled, a news reporter gathers opinions on the Chainsaw Man from the crowd. Among them is the unassuming Denji, who gives "Chainsaw Man" high praise, and even attempts to give out his phone number before the reporter loses interest. It is then that Yoshida appears next to Denji. Yoshida tells Denji that he cannot let his secret identity get out, as he is part of an organization that wants to keep his life peaceful. Denji is not interested in this, as he actually wants people to find out his identity, that way he can attract the ladies easier.

Denji tries to get Asa's attention by telling her he's the real Chainsaw Man, but she doesn't believe him and calls him a loser. She leaves, and Yoru tries to convince her that he is Chainsaw Man, but she just doesn't buy it. They decide that they should hunt a Devil and bring it to the school to lure the real one out. In the meantime, Asa wants to visit Yuko.

She gets to her house, and they sit with each other telling secrets. It's then revealed that Yuko made a deal with the Justice Devil so she can read her mind, now she knows about Asa and Yoru. She wanted to make the contract so she could get closer to her and decides she's going to "handle" her bullying problem and tells her not to come to school tomorrow.

Asa tries to reason with Yoru, to convince her to talk Yuko out of it, but Yoru steals her body and decides they're going to kill Yuko for their first hunt to get into the Devil Hunter's Club.

Yoru arrives at the school and confronts Yuko, who transforms into the new Justice Devil. They begin their brawl, but the Justice Devil is able to read all of Yoru's movements. Justice kills several students she believes are "bullies," while Yoru is unable to defeat her. Realizing her effort is useless, she takes decides to leave the battle up to Asa as a last-ditch effort. Asa tries to reason with Yuko, but when all else fails, she turns the uniform her mother gave her before she died into a sword and dices the Justice Devil into a million pieces.

Distraught that she killed her only friend, she begs for her to come back to life. That is when a girl with strange eyes appears in the doorway and says she can revive her for her- she'll do anything for her little sister.

Moments later, the Justice Devil's head, now a hundred times its size, crashes through the school walls. Chainsaw Man soon arrives to deal with her, leaving her guts strewn across the floor. Yoru notices him and decides now is her chance to deal with him. She takes off Asa's uniform to turn it into a sword and begins her assault on him, however Denji is whisked away by Yoshida's Octopus Devil arms.

Later that night, Yoru is worried Denji feels that she's too weak to fight, when she hears a knock on the door. It's Yuko, whose face now resembles the Justice Devil. She tells her she's leaving to find her Devil Hunter relative who she thinks can heal her, and only stopped by to say goodbye to Asa, and to warn her that the Justice Devil is still at the school. As a parting gift Asa gives Yuko her shoes, mirroring the kindness she showed to her earlier.

Yuko leaves, and while Denji, Asa, and Yoru's mysterious sister are sleeping, Yuko seems to be killed by someone resembling the Chainsaw Man.

Trivia

 * Yuko calling Asa "Chainsaw Woman" is subtle foreshadowing that she is aware of Yoru's possession of her, as "Chainsaw" and "War" are pronounced similarly in Japanese, being "Chēnsō" and "Sensō" respectively
 * The title of the first chapter and first volume of Part 2, Bird and War, is reminiscent of the first chapter title of Part 1, Dog and Chainsaw.
 * The title of Chapter 2 may be a reference to the idiom, "killing two birds with one stone." The two birds in this chapter are Mitaka and the War Devil, two minds inside one body, both called "birds" because of the form the War Devil takes in the previous chapter.
