Miraculous World: Paris, Tales of Shadybug and Claw Noir

It only takes one decision to become a hero.

Miraculous holders from another world appear in Paris. They come from a parallel universe where everything is reversed: the holders of the Ladybug and Black Cat Miraculouses, Shadybug and Claw Noir, are villains, while the holder of the Butterfly Miraculous, Betterfly, is a superhero.
