Unable to repay my student loans, I had no choice but to work part-time as a demon hunter.

Gordon never expected his new life to begin with a debt slip. After transmigrating into the steam-choked, supernatural metropolis of Lundnium, he finds himself a penniless scholarship student at the Royal Academy of Natural Sciences—no noble lineage, no hunter's license, and no inheritance to his name. All he owns is a crushing hundred-gold-pound student loan and a peculiar pair of eyes that pierce through the city's grimy veneer. While the rest of Lundnium sees only waste, pollutants, and refuse, Gordon perceives the hidden value lurking within. He quickly realizes that in a world where others rely on guesswork and experience to identify source matter, his vision gives him an unassailable edge: he can lock onto valuable targets, devour their essence, and grow stronger. What begins as a desperate side gig to repay his debts soon evolves into something far greater. Gordon takes up part-time work as a demon hunter, scouring the dangerous underbelly of the city for bargains that others overlook. As his reputation grows, the influential take notice—a professor hires him as an investigator, a noblewoman offers her patronage, and a fierce hunter girl blocks his door with a drawn sword. Even the cultists, who curse his name from the depths of the Blackwater River, cannot ignore his rising power. From an unknown student haunted by unpaid tuition, Gordon ascends into a figure that the entire world can no longer overlook. But with every secret he uncovers and every source he devours, he edges closer to a truth that may redefine the very nature of his existence.
