User blog:XenoChroFan/Could you help me finding a chapter?

I'm currently working on a paper about this series, and I have to reference cannibalism, Ghoul biology and the evolution/derivations from human beings addressed in the TG universe. Particularly, I have to use this annexed image; however, I don't have the reference, so I ignore on what chapter of the manga I can find it. Can you give me a hand with it? I would appreciate it very much.

Gretings, guys
