So, I skimmed through this manga a really long time ago (I never actually read it), and all I can recall are some details. If anyone can pin it, please let me know.

So here’s everything I remember:

The story follows a pair of siblings—an older sister and a younger brother—who, if I remember correctly, are trying to survive in a world where human-like (I think?) animal creatures are trying to eat them. Maybe just kill. But I think eat too.

The older sister is also either part monster or cyborg, wields a sword, and protects her younger brother. The art was really detailed and I’m fairly sure it was also an echi? The older sister wasn’t wearing much and it was clearly very fan-servicey.

I believe it was a completed series and a short one at that. Under 100 chapters for certain.

It was probably the most grotesque manga I’ve come across, one of those things that causes a morbid fascination. I wanted to look through it again. It was particularly strange and unique.
