Summary
The Devil Is A Part Timer
The people of Ente Isla are living in constant fear and darkness. Notorious Demon Lord Satan has declared war on humanity in his quest for global domination. But when Emilia, a brave hero, puts a stop to his conquest, Satan and his devoted general, Alciel, retreat to Earth. In a bid to regain his power and authority, Satan faces the challenge of existing in a world devoid of significant magic. Despite this, he assumes a human persona and lands a job at a fast-food restaurant while Alciel searches for a way to restore their strength. As Satan grows ever more determined to conquer both Earth and Ente Isla, he surprises himself by climbing the corporate ladder as a full-time employee. Alas, his designs are once again thwarted by Emilia, who swears to vanquish him once and for all.
