Arise! Cure Cobalt (intro)

What would you do if you found out you and your sister are superheroes?

Maybe you'd be excited, maybe you'd be scared, maybe you'd be in disbelief. For Sonic and Amy Satomi, it was all 3 at once.

And when evil monsters known as "Shadow beasts" attack Earth to kill Amy and capture Sonic, the siblings must use their new-found powers to fight back, with the help of some friends whom know more about the siblings than they do.
