In this world, the concept of "Level" exists. Other than those who are living as a monster slayer, at the most, ordinary peoples "Level" is between 1 to 5. Because of that, those who work as monster slayers are special people, bestowed by the Gods a special "Job". There are eight special "Jobs" that have battle abilities, and three special roles that differentiate from the eight battle classes. However, within the large population only a few earned those blessings. At most, all are "Villages", which is the lowest and weakest, tasked with daily duties. A "Villager" doesn’t have the ability to fight; trying to defeat a monster is suicide. One day, a two years old child noticed something. If you defeat a monster, you can be rich.
