Chainsaw Man has a concise narrative. It doesn't stop its ongoing story to clear up how aspects of its world work; that information is sown seamlessly into the dialogue. However, that means details fans are curious about will be left unanswered. One such detail that has rattled fans the most was the status of the hybrid Devils Makima controlled. For all anyone knew, they died along with her. This would be a shame because Reze, Denji's first love, was among them.
