The Devil Is A Part-Timer! SP Vol. 1 (Light Novel)

When Demon Lord Satan Jacob’s plans to conquer the world of Ente Isla are thwarted by hero Emilia Justina, he and his demon general Alciel escape through a magic gate and find themselves in modern day Tokyo! However, due to magic not existing in the world, they are powerless and forced to act and live as normal human beings. In order to survive, Jacob, now named Sadao Maou, gets a job at a fast food joint while Alciel, now named Shiro Ashiya, begins working as a housekeeper while trying to find a way to regain their magical powers. And they aren’t alone: hero Emilia has come through the gateway as well! Now named Emi Yusa, she works by day at a call center while she tries to track down Jacob and ensure he doesn’t destroy the world. But how’s a powerless, broke part-timer supposed to do that anyway?
It’s the busy summer season at Chiho’s family’s farm, and they’re short on harvesters! Sadao, who is out of work due to MgRonald being closed for renovations, decides to head down to the farm to help out together with Shiro and Hanzo, and for some reason Suzuno and Emi tag along too! How will Sadao and the gang handle life on the farm?
