How Does Gojo CSM Fanfiction Explore Character Relationships Differently?

The crossover between Jujutsu Kaisen and Chainsaw Man throws two very distinct flavors of chaos into a blender. Gojo's overwhelming, almost detached power and Denji's raw, desperate survival instinct create a dynamic I haven't seen replicated elsewhere. Canonically, Gojo exists on a lonely peak; most relationships are transactional or pedagogical. But drop him into the CSM world, where humanity is often more grotesque than the Devils themselves, and you force a different kind of engagement.

I've read a few where Gojo becomes an unofficial mentor to Denji, not in jujutsu, but in navigating a power system that operates on desire and contract rather than cursed energy. The exploration isn't about teaching technique, but about Gojo confronting a type of 'strength' utterly divorced from the six eyes or limitless. He can't just delete a Devil with hollow purple; he has to understand its nature, its contract. That reframes his entire approach to relationships from supreme authority to a more negotiated, curious partnership. It's less about him being the strongest and more about being the most adaptable.

Some fics even play with the idea of Gojo finding the CSM universe refreshingly free from Jujutsu society's burdensome politics, which lets his more playful, irreverent side actually form genuine bonds without the weight of being the 'honored one' every second. You see him connecting with Power over shared chaos or with Aki over a twisted sense of duty, relationships that would be impossible in his own world.

It mainly explores mentorship differently. Gojo's teaching in JJK is famously hands-off, almost careless. With Denji, he's dealing with someone who can't be taught in a traditional sense. The relationship becomes about providing stability rather than lessons. Gojo becomes an anchor in Denji's chaotic life, a consistent, powerful presence that doesn't want anything from him, which is a novel dynamic for both characters. That simple premise generates a lot of quiet, character-driven moments the original action series don't always have time for.

From a structural angle, the fusion forces a reevaluation of power dynamics. Gojo's strength in JJK is absolute, a narrative endpoint. In CSM fanfiction, it becomes a variable. How does Infinity interact with a Devil's contract, which isn't a cursed technique but a conceptual agreement? This uncertainty shifts the relational foundation. He can't dominate; he has to collaborate.

I've noticed authors often use Makima as a foil. Both are control freaks, but where Makima's control is hierarchical and paternalistic, Gojo's is often performative and isolating. Watching them navigate each other—not in battle, but in a tense, strategic dance over influence on Denji or Power—creates a political relationship JJK rarely explores for Gojo. It's less about fighting together and more about maneuvering around each other's philosophies of control, which exposes new facets of his character I wish the manga touched on. The best fics use the crossover not for fights, but for these quiet clashes of ideology.
