Fan Casting Chainsaw Man

Again, same as JJK. I was unsatisfied with some Chainsaw Man fancasts, but problem is not just because of the whitewashing or race-swapping, but some people trolled the castings with wrong and awful suggestions for the characters (example: Danny DeVito as Denji, The Rock and Billie Eillish as Power, Giancarlo Esposito as Makima etc.). There's many CSM fancasts here but only a minority of them are not whitewashed so i want to create one with japanese actors. But please, if you want to contribute, DO NOT suggest the wrong actors/baffling and awful suggestions and no raceswapping, thank you : )
Denji is a destitute young man who lives in a world filled with bloodthirsty monsters called Devils. One day, he befriends Pochita, who is a Devil dog-thing that is also a literal chainsaw. If that wasn't already a weird, things take a real turn when Denji is murdered by gangsters, and Pochita fuses with his soul to save his life. This turns the perpetually hungry and horny Denji into the titular Chainsaw Man, who ends up hunting other Devils for the enigmatic Makima, a woman who works for a governmental bureau of Devil Hunters, and strings Denji along with vague promises of sex and fortune, even as she treats him as little more than a dog himself.
