I think what makes this author so entertaining to read and what makes me keep coming back is how extreme he goes. Everything is taken to the most exaggerated version of the joke.
Like, in comparison to the other gender ratio manga, which is just relying on the basic premise. The fun is the absolute depravity that every single character is drenched in, every character is a major simp. Like I could care less about the ecchi, I just find this shit funny.
