Chapter 99

Two Birds (２羽, Ni wa) is the 99th Chapter of the Chainsaw Man manga.

Summary
The next day after the War Devil killed Tanaka and the Justice Devil, Mitaka wakes up in bed realizing she is missing her scars. She turns to her side to find herself, with scars on her face and spiral eyes, sitting on her bed. This is the War Devil, who reveals to her that it killed her but kept half her brain intact. Its plan is to wage war with the Chainsaw Man, but in order to do so has to assimilate into the high school where he supposedly attends. If Asa doesn't comply, she will be killed completely.

The two of them walk to school together, and Mitaka finds out that only she can see the War Devil, as it is a hallucination from her mind. When they arrive at school, they are approached by a boy with black earrings who asks if she's okay. To Mitaka, the War Devil tells her to ask the boy if he knows where the Chainsaw Man is, but she refuses. The War Devil suddenly enters her body, and Mitaka takes the War Devil's place outside her own consciousness. The War Devil uses Mitaka's body to ask where the Chainsaw Man is, but the boy just transferred there so he is unaware. What he does know is that there is a rumor that he joined the Devil Hunter Club.

Satisfied with this new information, the War Devil then asks the boy if he will be her boyfriend, but he declines and walks away. The War Devil reveals to Mitaka that anything that belongs to it becomes its weapon, and its goal is to turn as many humans as possible into weapons so it can wage war on the Chainsaw Man. Mitaka is horrified at the situation that she's found herself in, and desperately wants her body back, but the War Devil promises that once they kill the Chainsaw Man, they will return her body to her.

Mitaka forces herself to go to a Devil Hunter Club meeting, and there she is paired with two other students to hunt down a devil by the end of the week as initiation into the club. One of the students she was paired with was the boy she met in the front of the school that morning.

Trivia

 * The title of this chapter 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.
