The part in the manga that intrigued me the most was the different body types with variety of features in small details (like the nipples and face designs) the MC can create.
As an artist, you would know about the "Same Face" Syndrome that I notice in most of the Manga's, plagued with same body types and face but with different hair style. Which this manga does not have that problem.
While the sculpted bodies are quite sexy, I believe the MC is only interested in the beauty of the Female Body without any malicious intent, this could've been easily been just an Ecchi manga that has pervy scenes of him wanting to do naughty stuff with different bodies. But he only wants to make a powerful and beautiful female body that can be take down any Yokai.
And the Side Characters are also pretty great, I adore his lil nerdy classmate. I look forward to seeing how this series goes.
(Quite impressive that this manga has so many naked sexy bodies, but instead of feeling horny, it made me impressed with each different sculpture design, wonder if he'll make a shortstack one day.)
