In a world where the justice system fails, and money can buy you your freedom and place you above the law, one girl takes "justice" into her own hands. Her normal name is Zelda Akita, and on the outside shes just a ackward office goth girl, trying to avoid the spotlight. Her co-worker Faith tries to reach out to her and open her up to the world but she just uses her shyness to turn her away because deep inside she has a dark secret. As soon as the blackness of night comes she embarks on her murderous path of her own of brand corporal punishment to the cities most corrupt. She lurks in the shadows and uses her master skills of deception to humble those who tink they're above the law. She is Josei No Akuma, The Demon Ninja.
