The Devil is a Part-Timer!

When the Demon Lord Satan finds himself unceremoniously banished to modern-day Tokyo, his grand ambitions of conquest take an unexpected detour. Stripped of his powers and stranded in a world he barely understands, the once-feared ruler of Ente Isla must now navigate the mundane realities of human life, starting with finding a part-time job at a fast-food restaurant. But even flipping burgers can't keep the forces of good at bay forever. As former rivals and allies from his old world begin to appear, Satan — now "Maou Sadao" — discovers that surviving in a capitalist society might be an even greater challenge than conquering a fantasy realm, all while trying to maintain his cover and perhaps, just perhaps, plotting his eventual return.
