Hataraku Maou-sama!!

Sadao Maou is still working at a fast-food restaurant in Tokyo after leaving behind his throne and most of his demonic power in Ente Isla. His routine changes when a child named Alas Ramus emerges from a golden apple and immediately declares Sadao and Emi her parents. Two former enemies suddenly share responsibility for a girl who knows nothing of their old war, but her existence is soon linked to Emi's holy sword and powers the angels want returned. Archangel Gabriel arrives to take both Alas Ramus and the blade, dragging Ente Isla's conflict back into Sadao's ordinary life. Between shifts, rent, and supernatural attacks, Sadao and Emi must protect a child who chose them and discover how much their old labels still define the people they have become.
