Maou-sama no Kinyoubi

Long ago, a fearsome Demon Lord was defeated in battle by a legendary hero. In her final moments of desperation, she unleashed a spell that spiraled out of control, abruptly transporting her from the demon realm to modern-day Japan. Stripped of much of her strength, she soon discovered an unexpected advantage: consuming contemporary human food allowed her to rapidly and efficiently replenish the magical power she had lost. Once fully restored, she returned to her rightful place as the ruler of the demon world. Yet, despite her supreme authority, she finds herself repeatedly sneaking back to Earth, drawn by the irresistible allure of cheap, easily accessible convenience store meals. Her secret excursions take an unexpected turn one evening when she wanders into a back alley in a bustling downtown district. There, she intervenes to rescue a young woman who is being harassed by a group of men. As a token of gratitude, the girl leads her savior to a small, welcoming oden restaurant. For the serious and rigid Demon Lord, this chance encounter becomes a revelation. Far beyond mere sustenance, she discovers truly exquisite food and drinks, along with something she never anticipated finding—genuine friends to share them with after a long day's work.
