Let's Talk Chainsaw Man is a weekly podcast where I talk about Chainsaw Man. I'm just a casual manga and anime fan with garbage opinions.
The new Chainsaw Man arc starts off with Asa Mikata, a introvert at her local high-school. One day, her homeroom teacher introduces her class to Bucky, a chicken-devil and has the class host him for 3 months, with the class having the choice to kill him or spare him at the end of the 3 months. Once the 3 months passes, the class decides to spare Bucky, having grown attached to him. Bucky encourages Asa to come out of her shell, but is tragically killed when Asa accidentally trips while carrying him.
Later, her teacher and one of her classmates, come to visit her in order to comfort her. Her classmate reveals she made a deal with the Justice Devil, as she jealous of her teacher's attraction for Asa. She kills Asa, but a devil revealed to be the War Devil comes and takes over her body, killing the classmate. Now, Asa, with the War Devil "Yoru" sharing her body, sets out to kill Chainsaw Man, who is revealed to go to her high-school, on the condition that Yoru leaves her body once she kills him.
