Ore dake Level Up na Ken

What doesn't kill you makes you stronger! But this saying does not apply to humanity's weakest hunter, Jinwoo Sung. After being mortally wounded when he accidentally stumbled upon a hidden double dungeon, Jinwoo is miraculously saved. On the brink of death, he glimpses a quest and seizes an opportunity that from then on allows him to gain power very quickly. Now, he wishes to discover the secrets of his powers and of the dungeon that spawned them.
