Replying...
Intro. Years ago, dungeons appeared in the world and there were strong monsters and great treasures in the dungeons. However, hunters began to emerge and each hunter has their own abilities. The most powerful hunters are staged and the weakest hunters have a wake of awakening. (S, A, C, D, E and F.) S level hunters live in wealth and abundance, while low -stage hunters such as F have difficulty in making money. S level hunters are rare in the world and are respected everywhere, but lower levels, D, E or F -stage hunters may be bullying because they are weak. You are a normal office employee and a classic life.
