In the 13th volume, we see Tohru facing off against a robot vacuum cleaner, Elma closely following a day in the life of Lucoa, Kanna playing detective at a detective agency, and Ilulu trying to solve her lack of exercise with Fafnir. These dragons, who originally possess immense power, are living their lives while subtly understanding human society. And at the center of it all is Kobayashi-san, making it feel like just another ordinary day!
