In a world where massive gates lead to perilous dungeons, and hunters are humanity's first and last line of defense, A-Rank Hunter, Hanny Ace Jimuel De Leon has clawed his way to the top. Once an ordinary hunter, Ace becomes the youngest CEO of the Philippines' most powerful guild, Iron Pulse Technologies (IPT)—a guild not only responsible for fielding elite hunters but also for innovating the weapons that keep them alive.   But at the peak of his success, Ace finds himself utterly alone. His relentless ambition and ruthless decisions have alienated his friends, ruined lives, and driven away his wife. When the suicide of an old comrade forces him to confront the human cost of his actions, Ace begins to unravel. Haunted by guilt, regret, and even visions of the dead, he questions whether the guild’s survival is worth the sacrifices he has made.   As Ace was miraculously regressed to the past where he just started as hunter, Ace must navigate the treacherous waters of guild politics, public outrage, and a growing regrets on his actions towards those he once called allies. With enemies both within and outside IPT, Ace realizes that being a true guild master is about more than power and success—it’s about earning back the trust of the people who believed in him.   Can Ace redeem himself and rebuild the guild on a foundation of integrity? Or will his obsession of climbing towards the top cost him everything, including his own humanity?
