Years ago, Humanity was not greeted by the warm shine of a new day like every morning. What greeted them was a sudden "Gate". A Gate that connects the real world to another. The Gates which would later be known as Dungeons started to appear all over the world. Monsters that had never been seen before started to pour out from these gates, and so Humanity tried to defend itself, but such things as firearms or even nuclear bombs would work. But not all hope was lost. Some people around the world began to receive the power to hunt monsters within the Gate. And so humanity was able to fight back against monsters.

These people would later be known as «Hunters». However, not all hunters are powerful.

His name is Ryan Armstrong , an F-rank Hunter. He's someone who has to risk his life in the lowliest of catacombs. Its title is "one of the weakest hunters in the world".

Having no skills whatsoever to display, he barely earned the required money by fighting in low-leveled catacombs… at least until he found a hidden catacomb with the hardest difficulty within the E-rank catacombs!

In the end, as he was close to death, he believed his life was worthless until….

A certain image appeared in front of him.

「The 'Demon God' praises your unbreaking will. 」

[Congratulations, you have become a "Player".]

He was given a chance now.

A special one at that.

Watch Ryan's journey as he tries to make it to the top and become the most powerful hunter in the world.
