On a rainy day, Oscar decides to search his attic for his grandfathers old stuff. He stumbles upon a box, which he later figures out is called a Miracle Box. It's filled with jewels-- 17 to be exact, and they weild magical creatures called Kwamis which inhabit the jewels, turning normal civillians into heros with special powers. While Oscar is finding the Miracle Box, somebody else has made a discovery-- a discovery of the Butterfly and the Peafowl jewel. And they are relentless, turning normal civillians into villians with magical butterflies called Akumas. Little does Oscar know that he is in more danger than he realizes and he has to get back the Butterfly and the Peafowl Miraculouses with the help of his team... before it's too late.
