The Devil Is a Part-Timer!, Vol. 11 (light novel‪)‬

DO YOU WANT FRIES WITH YOUR HELLFIRE? Thanks to the efforts of Maou and friends, Emi has made it back from Ente Isla in one piece-at the cost of her job at the call center, after all those pesky, unexcused absences. To add insult to injury, Maou confronts Emi with an invoice for "expenses incurred" during the rescue. Emi is shocked, but her pride as the Hero means she can't abide being indebted to a demon. Soon, she's dipping into her savings and searching for a new job to pay her tab. Meanwhile, Urushihara has been sequestered in a hospital, where his body undergoes frightening changes... just as Maou (shockingly!) refuses to go to work?!
