Jung-woo is stuck in a reincarnation cycle along with his nemesis, Shin-Ryong. Ever since he was little, he had a dream. He wanted to become strong enough to conquer Murim. However, things did not always go the way he planned. Shin-Ryong defeated him on every occasion. At this point, Ha Jung-woo had been reincarnated 5 times and was defeated yet again. When he was reincarnated for the sixth time, he is born into the modern world. Being born into a new world changes Jung-woo's goal, as there is no Murim in the modern world. (Source: POCKET COMICS)

Gang Mu-Jin takes priority on his family and the people around him. Nothing is more important than them, not even the world of Murim when it’s in danger.

In the modern era, dungeons and monsters appear, and awakened humans emerge. The awakened, possessing extraordinary power and abilities, became hunters to protect the world, and a power structure formed around them. But this was all irrelevant to Mu-Jin... or was it? Due to his female friend Ji-Su, who had returned, Mu-Jin's life, which had sought normality, changed spectacularly! Sixteen-year-old Mu-Jin receives a thunderbolt confession from Ji-Su, his childhood friend he's known since they were little. She claims to have returned from a distant future where an evil organization conquered the world, making it a dreadful place to live. She says the Mu-Jin she saw before dying crushed enemies with overwhelming power. Therefore, “You... become my comrade!” Though this absurd confession makes Mu-Jin slightly concerned about Ji-Su's mental state, his arrogant conceit, thinking a hunter's life might be fun, leads him to enroll in the Hunter Academy. A born genius with a body of steel and sharp wit, the ultimate overpowered munchkin Mu-Jin enters the academy with outstanding grades despite minimal training and becomes a disciple of the King of Power. The only thing different from the past is Mu-Jin. Even so, can Ji-Su change a future destined only for destruction? (Source: KakaoPage, translated)
