The Sisters of Divine Mercy and Unrelenting Atonement are servants of God, operating in secret as the Ninja Nuns. The five sisters smite sinners in God's name and deal out punishments for wickedness. Their shadowed pasts make them perfect for crusading against forces of darkness. Only a few know who they really are--ruthless nuns to be feared, and not in a "rap your knuckles" way. After battling the Church's ages-old nemesis the Freemasons, they uncover a new threat when a captured agent confesses to stealing Church money for a "Specter Organization." Now the five Ninja Nuns are kicking ass and taking names--but God already knows who the wicked are.
