Gina from HauntedFlower.com and HauntedFlowerReviews.com reviews "Darker Than Black" starring the voices of Jason Liebrecht, Brina Palencia, Kent Williams, John Swasey, Kate Oxley, and Laura Bailey. In this series, contractors have superpowers and are used as highly efficient assassins. For each time they use their power, they must pay a price. It's like X-men but different.
