A father and son get revenge by killing the Giant that devoured their family. But this unlocks something otherwise unknown to them at the time: Adventure Classes.
Now joining up with the ranks of the Heroes in the world, their realm gets a whole lot bigger, including the stakes.
Leaving their simple life in the woods behind, they become the Giant Slayer and Giant Eater, two extremely rare classes that will be the key to toppling the monolith evil that plagues the land.
With these new powers and responsibilities come consequences, and both father and son's burdens become heavy when they realize exactly what it is they've stumbled onto.
