A decade ago, “the Gate” emerged and linked the real world with the supernatural realm. Superhuman powers were bestowed upon ordinary individuals, allowing them to become “Hunters” who battled against malicious creatures. Sung Jin-Woo, a Hunter at the age of twenty, was deemed the “World’s Weakest” due to his pitiful strength, even weaker than an E-Rank Hunter. However, he persevered by tirelessly hunting monsters in low-rank Gates to pay for his mother’s medical expenses. Yet, Jin-Woo’s dismal existence takes a sharp turn when he wakes up in a hospital three days after a botched mission where he thought he was the last to perish. To his surprise, he sees a strange screen floating before him called the “Quest Log.” It requires him to complete a daunting and unrealistic training program or risk facing dire consequences. At first hesitant due to the severity of the task, Jin-Woo soon realizes that it may be his chance to become one of the world’s most formidable Hunters.
