“the Gate” appeared ten years ago and connected the real world with the sphere of magic and monsters. The ordinary people were given superhuman powers to combat these vile animals and they were called “Hunters.” The twenty-year-old Sung JinWeo is one Hunter, but because of his pathoscope compared to an even meagre e-rank he is known as the “World’s Weakest,” Still, in the low-rank Gates he hunts monsters tirelessly to pay the medical bills of his mother.
However, when Jin-Woo — the only person left to die in a mission left terribly wrong, believes himself to be — wakes up in a hospital three days later to find a mysterious screen floating in front of him. This “Quest Log” requires Jin-Woo to complete or to face a proper penalty for an unrealistic and intense training program. At first reluctant because of the rigor of the quest, Jin-Woo soon found that it could only transform him into one of the worst hunters in the world.
