Shouta Magatsuchi, a young mage still mastering his craft, tries to summon a demon and instead calls up Quetzalcoatl, the dragon god known to Miss Kobayashi's Dragon Maid readers as Lucoa. Bound to serve as his familiar, Lucoa takes an unusually hands-on approach to solving Shouta's everyday troubles, dragging him into one awkward scheme after another. This spinoff stays with the two of them at home, with Tohru and Kanna turning up along the way.
