What happens when gods decide that they need warriors to fight against enemies even they cannot defeat?

Obviously, they would create places where said warriors are more than likely to appear. Worlds, teeming with monsters and cruelty around every corner were thus chosen to be the living space for certain promising individuals and humans, in hope of creating heroes that may defeat the undefeated.

I, a more or less normal vampire, am one of said individuals who were reincarnated into this world. Honestly, I only wanted to eat the best food, but someday, the food itself turned out to be quite interesting. Thus, a vampire lived quite happily together with a human (the food), an elf and, why not, a literal shadow.

At least, that's what could happen if the world wouldn't burn around us, time and time again. It´s not like I hate it though. A few deaths here, a bloodbath there, these are things that a crazy vampire like myself needs to find true happiness.
