also you may try homunculus if you haven't already read it https://mangadex.org/title/1543/homunculus
Oshimi Shuzo's work is hit or miss for me but it might be what you're looking for as well
@FluentInManganese she's definitely going through something, you can read her statement in the first comment i posted in this thread. your theory would make more sense if the chapters were only removed from rigeng, but minami is also halting her activities on weibo as well.
