The Devours System

In a world where systems are standard, from common leveling systems to evolving dragon systems to even god-making systems.I'm given a named one once again after losing my original one long ago.  Now not only does I get stronger from killing but also from eating my prey. I don't know why, but I yearn to kill and eat all to get stronger.Maybe it's the dreams I've had since I was bestowed with this system, or maybe...something more?.... Can I live up to my dreams and what's been given to me?
