In a magical world, the naive and spunky Padadu is training to be a magical girl — a title reserved for those who have defeated many in battles, and earns them a right to visit Earth. Along with her arch rival Pipin, seductive and manipulative Myumyu and the fugitive Nonononn, Padadu and her magical sentient fish costume travel the world in search of fun and adventure! But the tyrant queen Purilun and her lackey Zucchini are hot on their trail; will Padadu ever become a real magical girl?
