Chainsaw Man excels at keeping readers on their toes, often making them guess what happens next before throwing a complete curveball. While the story itself continues to build with each chapter, the focus ultimately shifts to protagonists Denji and Pochita. Their meeting, bond, and subsequent contract initiated a chaotic series of events, to say the least.
With a lot yet to come, there is a possibility that Denji and Pochita will never truly be free. This pertains to their Hybrid nature and its attributes. Thus, by the end of Chainsaw Man, the teenager might end up breaking ties with Pochita for the better. This seems unthinkable, considering all they have been through and will continue to face. However, letting his best friend go may be Denji's best chance at moving forward.

Chainsaw Man: Denji and Pochita's ultimate fate may see them part ways by the series' end

The thought of Denji and Pochita not being a unit may seem uncanny to fans of Tatsuki Fujimoto's series. They have been together since Denji was a child, enduring considerable hardship. Through Pochita's contract, Denji became Chainsaw Man and fought his way through adversity. Now, the pair seems to face another tough task ahead—the Death Devil.
Whatever happens in future chapters, there is reason to suggest that Denji will part ways with Pochita by the series' end. To begin with, we must reference Hybrids, particularly Quanxi. As seen with her (and others), Hybrids do not seem to age. While this has not been explicitly clarified, Quanxi appears the same throughout, and her title of "First Devil Hunter" implies she has been that way for a long time.
In other words, Chainsaw Man's Hybrids are immortal. Their appearance remains unchanged as they reach a certain point in development. In Denji's case, he is an adolescent. Since he should not age, he will remain a teenager forever. Teenagers are often characterized by traits like impulsiveness, insensitivity (at times), chasing their dreams, limited clarity about the future, and a dreamy disposition.

Once again, relating all this to Denji, the main focus for his character has been the pursuit of his dreams. Pochita made a contract with him so he could live the boy's dreams. However, if Denji breaks the contract, he and Pochita could become unbound (similar to when Pochita took over as Denji consented to be a dog for Makima). In essence, Denji survives by chasing his dreams while maintaining the contract.
In this situation, Denji cannot grow beyond his adolescence. Although throughout Chainsaw Man Parts I and II, he undergoes character development, it is circumstantial and imparts valuable lessons to him. Nevertheless, he remains in a teenager-like state of mind. In other words, he is, and will continue to be, tied to pursuing his dreams, which are somewhat unrealistic and unsustainable.
Therefore, the concept is that he will eventually have to part ways with Pochita. This would enable him to evolve from his current self and truly achieve the normal life he desires. As depicted in the series, he jumps from one chaotic situation to another, rarely able to enjoy a moment of peace. Thus, he appears to be trapped in a never-ending cycle that continually drains him, until he decides to let go.
To attain genuine happiness—one he won't fear losing or actually lose at some point—he must take a grim step. To move forward, he must approach reality rather than continue pursuing dreams in the manner he does.
Final thoughts

To conclude, Chainsaw Man presents a narrative that is as unpredictable as it is emotionally charged. At its center lies Denji’s journey. His bond with Pochita serves as both his salvation and his curse—survival, yet entrapment in a loop of unending chaos. As the series divulges more about Denji’s hybrid nature, the inevitability of him having to sever this bond with Pochita increases.
Immortality may have frozen him in adolescence, both physically and emotionally. Attractive at first, he is likely chained to the pursuit of dreams that can never be fully realized. The idea of Denji and Pochita’s partnership ending is heartbreaking, but it also suggests necessary evolution—an escape from perpetual struggle for a grounded and peaceful reality.
If at its core, Chainsaw Man is about growth amidst the twisted, then separating from Pochita may be Denji’s biggest step toward maturity.
