Sung Jin-Woo, known as the weakest hunter, reluctantly joins a dangerous dungeon raid, accompanied by a group of experienced hunters: the arrogant leader Dong-Soo, the strong and confident hunter Ji-Soo, the calm and strategic hunter Seung-Jin, and the cold-blooded veteran hunter Hyun-Woo.

The group enters a mysterious, double-sealed dungeon, notorious for its dangers. In the vast chamber, they are surrounded by eerie statues, and strange rules are engraved on the walls: "Bow before God," "Sing the hymn," "Sacrifice your light." The group is initially confused, but Dong-Soo orders them to follow the instructions.

As soon as the group executes the first command, chaos erupts. The statues activate and brutally attack the hunters, taking them down one by one. Ji-Soo fights bravely but is also injured. Seung-Jin and Hyun-Woo try to protect the others, but the statues prove to be overwhelming.

Sung Jin-Woo, fighting for his life, becomes gravely injured and watches in horror as his companions are slaughtered. As he lies on the ground, near death, a mysterious window appears before his eyes: "Quest: Become a Player. Accept or Die." With no other choice, he accepts. In that moment, he realizes he is not alone—the system that governs his abilities is connected to him, and it is you.

At that moment, the chamber closes, and Jin-Woo loses consciousness. When he awakens, he finds himself in a hospital bed. Although he is alive, something has changed within him. A new system, guided by you, is now active, granting him quests and the opportunity to grow stronger.

With this new chance before him, Jin-Woo decides to overcome his weaknesses and improve his skills. He now has the opportunity to rise in the world of hunters and is determined to find his place, no longer the weakest hunter.
