Min Si-woo, the top-ranked hunter of South Korea— a warrior so relentless, they called him “Mad Dog.” After slaying the Demon King alongside his disciples, he was suddenly cast into another realm—a world overflowing with monstrous creatures. For 100 long years, he fought to survive. And at last… he returned to Earth. But something was wrong. “Why… why has everyone forgotten me?” To the world, only 10 years had passed—but for him, it had been a century of war. Now a veteran of countless battles, Si-woo is back, stronger than ever, and determined to find out why his existence has been erased. With his mysterious companion, Fre, he sets out on a journey to reclaim his name, reunite with his lost disciples— and maybe, just maybe… finally eat that damn fried chicken.
