Yusibu: I couldn't become a hero, so I reluctantly decided to get a job.

Raul Chaser enrolls in the Hero Training Program to pursue his dream of being a hero and defeating the Demon King. The Hero Training Program, however, is put on hold indefinitely when the Demon King is vanquished and order is restored, making it impossible for anyone to become a hero. Two years later, Raul unwillingly accepts a job at Magic Shop Leon, a tiny electronics shop. The former hero-in-training is troubled by the tedium of working in retail, but all changes when a new worker shows up. He initially appears to be just a handsome guy, but "he" is actually Fino Bloodstone, a female demon. Raul's new coworker is the daughter of the deceased Demon King, thus she is not just any old demon either. When Raul is given the task of training this strange new employee, his life quickly becomes more exciting than it has ever been.
