Meanwhile, the humans are preparing for the rise of the next hero who will oppose their archenemies.Born as a mere stable boy in a lower-class noble household, Bel has lived his life tending to the noble gardens, pruning roses for banquets he would never attend. He is nothing more than a lowly servant in a world ruled by noble bloodlines and magic.However, his fate changes when a demon attack devastates the household.
