小林さんちのメイドラゴン

Office programmer Kobayashi opens her front door one morning to find Tohru, a dragon from another world, standing in human form wearing a maid outfit. The night before, a drunk Kobayashi had stumbled into the mountains, pulled a holy sword from Tohru's back, and invited her to move in. Grateful and smitten, Tohru throws herself into housework with dragon-scale enthusiasm, and other dragons start drifting into Kobayashi's once-quiet apartment life: the child-like Kanna Kamui, the reclusive Fafnir, the food-obsessed Elma.
