I like chad MCs running harems it makes more sense than most harem manga where the mc is an absolute retard beta mc who also happens to be a chick magnet just because (???)
The way I see it Chainsaw man spent so much time in hell the world did a whole cycle to back when it started cuz I don't know how the other dudes got brought back to life also Chainsaw man killed the ice cream demon so the ice cream has no taste
