The Secret Life of the Demon King

Following a devastating war against the human kingdom, Hell has been stripped of its former power and glory. The realm is now facing total financial collapse, lacking even the funds to pay its demon soldiers and servants. The situation is so dire that the Demon King himself, Hel, must rely entirely on two of his most loyal retainers just to survive. Determined to restore his domain to its golden age, Hel resolves to become self-sufficient and earn enough wealth to save his kingdom from ruin. To achieve this impossible goal, the Demon King ventures into the human world and takes on his very first job at a Knight's Private Club. Stripped of his royal authority, he must navigate an unfamiliar environment and adapt to the grueling demands of service work. His greatest challenge, however, lies in the clientele: many of the patrons he is forced to serve are the very knights who once fought against him as enemies. Now, Hel must conceal his true identity, endure their presence, and fight for his kingdom's future one paycheck at a time.
