Chapter 120

Triangle (トライアングル) is the 120th Chapter of the Chainsaw Man manga.

Summary
Immediately as she's attacked, Yoru begins to bark madly like a dog, much to Nayuta's amusement. Enraged, Denji asks why Nayuta did this, to which she explains that Yoru "spat on her property." Denji reiterates that he only belongs to himself, demanding that she returns Asa to her normal personality in an instant, which Nayuta agrees to do as soon as she's fed.

As soon as she's finished with her meal, Nayuta asks if Denji thinks it's a good idea that she turns Yoru back to her true self, as every prior woman he's met has only used him for their own selfish gain. When Denji insists he thinks Asa's different, Nayuta relents, noting that Denji can't get seriously hurt anyway. However, she has two stipulations; firstly, she's allowed to eat ice cream every day of the week, and Denji has to stop trying to romance Asa. Confused by the second one, Denji asks why, to which Nayuta remarks how horrible her scent is, implying she's somewhat aware of her fiend status. She then remarks that she'll alter Asa's memories to believe Denji stood her up for the date, as since they won't be seeing each other anyway, he shouldn't care what she thinks of him. Fearing for Asa's safety, Denji agrees to Nayuta's conditions.

Afterward, Asa stands by herself at the school entrance. Yoru says it's fairly late and figures they were likely stood up, so the two of them should target a different boy. Asa begins to ramble aloud to try and justify her earlier behaviour whilst also trying to sound indifferent about being stood up; something Yoru humours to a light extent. Asa remarks how she should be more focused on returning her body back to normal, only to see Yoshida asking if she's okay. When she says she's not really doing anything, he asks her if it would be okay for her to keep him company.

Trivia

 * The chapter title, Triangle, might be in reference to love or relationship triangles, where the differences between three characters’ friendships or love for one another are illustrated as a triangular chart.
 * Nayuta‘s remark of every woman trying to use Denji heavily implies that he informed her of the events during the Public Safety Saga, potentially including how he killed her previous incarnation.
