In a world of magic and monstrous threats, mercenaries live by a strict, pragmatic code: protect the client, obey commands, and honor the contract. But if the coin doesn't flow, neither does their loyalty. This harsh reality defines skilled warriors like Kyle and Hamel, whose paths lead them into treacherous dungeons and the eerie depths of the Cursed Forest.

Kyle, a master of the devastating 'Earthquake' sword technique, and Hamel, a seasoned fighter, quickly earn a reputation. Their assignments escalate from simple dungeon crawls to full-scale expeditions against the encroaching Demon Race, forcing them to confront horrors that threaten human civilization.

As Kyle's influence grows, earning him the trust of powerful figures and the responsibility of escorting high priestesses, the lines between mercenary duty and grander conflicts blur. The fight against demons rages across cursed lands and within the macabre Demon Realm. With political machinations stirring and the king's army on the move, Kyle and his comrades must decide where their true loyalties lie, and if their code can withstand the ultimate test.
