This could be the quintessential Shintaro Kago manga. It's got all his standard fixations - violence, sex, surrealism, body horror and dark humor. There's some grisly and disgusting stuff in here for sure, but it's framed in such a way that it's rarely disturbing; Sometimes, the author inserts something anachronistic (like a mangaka struggling to meet a perpetual deadline) just for the sake of a laugh, or draws an unnecessarily detailed diagram of sewing techniques. That's how Kago manga is: Scenarios are taken to their most extreme, absurd conclusions and it's sometimes funny in a surreal or tragic way. Good example: the first story hasa woman horrifically disfigured into a ghostly mass of vaguely-humanoid viscera and from that point on, she just shows up in the background, acting casual.

This is sort of a sequel to the other Korokoro Soushi, but really only in its shared setting (Edo period Japan) and themes. But yeah, with Kago, you'll feel disgust, shock, confusion, cringe and maybe even laugh, but you won't get bored.
