Chainsaw Man, vol. 3: Maten a Denji

Chainsaw Man is so intense but also unexpectedly funny at times. I'm curious how the tone was shaped during writing.

Some characters' motivations seemed to shift quite a bit — was this planned from the beginning or did it evolve as the story progressed?

The visuals are so striking and distinct — I wonder what influences or ideas drove Fujimoto's artistic choices.
