Dracon grew up in a world overrun by demons, and spent his entire life fighting on battlefield after battlefield hoping for a small chance of survival in the years preceding the demon invasion.
Humanity had lost to the demons 300 years ago, and now because of that defeat all of their third born children only had two options, become food for the demons or level up from the bodies of thousands of people that they slaughtered.
Dracon, however, gets lucky enough to receive a weapon the day before he turns level 2, finding it in the brambles and thicket of a previous battlefield after days of fighting in the rain as his clothes soaked up blood.
This weapon, a seemingly ordinary silver sword, however, has an extremely powerful skill imbued inside of it that may forever change the fate of humanity. With it, he's able to evolve into all of the demons that have taken over the Earth as long as he gathers their blood and strikes the last blow.
Starting from a goblin, and making his way up the line of demons, he fights for a chance to save humanity from the demon's butcher shops, and farms where all 3rd born and further generations are treated like meat to be harvested and eaten!
Warning: Contains gore, and a few difficult moral situations that aren't suited for everyone...
