A girl with extraordinary abilities given to her by mystical beings called the Sirens decides to become the superhero of her crime-filled town with her best friend, Fay. She's annoying, sarcastic, funny...and probably won't do very well, but find that out for yourself!

Emi Zero is a teen girl growing up in a world where there is only one country called Skiivia. She lives alone in a wooded village called The Black Forest, where the children live on their own. Her best friend, Dante, is abducted by an evil woman who is turning children into supernatural beings through serums to create an army to fight the alien invasion. Joining the mutants Suzuki, Destiny, Trixie, Rayman, Cayman, and Dante, Emi must save Skiivia, and herself.
