I guess an idea floating around my head, if not being feared is such a big deal, why did the chainsaw live with Denji? I don't mean this like an 'aha, plot hole!', more like, is there more we don't understand fully about the power's of devils?
Pochi made a contract with Denji, not asking for his fears, not asking for blood, but asking for his dreams. Not to be consumed, but to be fulfilled. As far as we knew, there was little benefit for Pochi in this deal. Maybe to hide from Makima, but they were already successfully doing that in dog form, and could have just left Denji to die after the zombies cut him into pieces. In fact, even after the contract was made, Pochi still tried to protect Denji from his repressed memories. Pochi didn't give Denji all his powers either, which seems weird considering every other devil human hybrid we've seen doesn't have a more suped up form like Chainsaw Man.
In the next few chapters, I think we might see more of an exploration and explanation of this relationship between Denji and Pochi. Because I think something that probably separates Chainsaw Man from other devils is probably connected to something more than fear.
Course I'm just spitting into the wind here. Firepunch was weird as hell, no reason to expect this series will be any different either.
