Homebrew Ghoul Species Details

From origins unknown these humanoid creatures cannot consume anything that isnt the flesh of the sapiant (int of 8). They resemble humans in all aspects except for their pupil turning red and sclera turning black when hungry, under extreme emotion, or hunting. They have also developed a new organ used in hunting known as a Kakuho that develops in multiple ways. When the organ mixes with a large enough amount of RC Cells it causes a Kagune to erupt from their body. The stronger the ghoul the larger its RC Cell count.
