Chainsaw Man chapter 158 featured the introduction of the Guillotine Devil, a highlight of the chapter, and Fami revealing she has peculiar deals with her summoned Devils. This led fans to speculate that the Falling Devil, summoned by Fami previously but not at full strength, could make a return. This could play a key role in rescuing Denji from Public Safety and possible threats from characters like Hirofumi Yoshida. While the chapter didn't reveal much plot-wise, it set the stage for potential future developments and surprises, characteristic of creator Tatsuki Fujimoto's storytelling style.

As Fami's powers and restrictions are explored further, fans eagerly anticipate what lies ahead in the Chainsaw Man series.
