Second series of the anime which follows the adventures of 'Contractors', assassins with special powers. The power of the Contractors is owed to a mysterious gate in the sky above Tokyo. However, while the Contractors may gain force from the gate, their sense of humanity suffers - making them perfect assassins. In this series, Hei (voice of Jason Liebrecht) and Yin (Brina Palencia) have escaped from the Syndicate and are drawn to Russia, where the fate of a young girl, Suou Pavlichenko (Alison Viktorin), threatens to draw them back into the deadly assassination game. Elsewhere, Misaki Kirihara (Kate Oxley) steps up her investigation into the activities of the Contractors and the Syndicate.
