Synopsis

In a world filled with beings called Hunters, who fight to save humanity from dangerous monsters, a Hunter nicknamed “the weakest” by others, Seong Jin-U, faces a tough life. One day, after a tough fight in a strong dungeon, his whole group is wiped out, and it seems his end is near. Suddenly, a Mysterious System picks him as its only player. This means Jin-U can now upgrade his abilities, maybe even past what anyone else has done before. Join Jin-U as he tackles stronger enemies, some human, some monster, while unraveling secrets hidden within the dungeons and finding the full extent of his powers.
