Blackmail

For as long as history remembers, Demons and Guardians have fought over Earth - a sacred gift from the great Mother, the source of all life. The Guardians' refusal to let the Demons wipe out humanity forged an unending hatred between them. Now, in Neo-Shinjuku City, their ancient war has nearly faded. Humans dominate the world, unaware of the hidden battle. But beneath the city's surface, a powerful Demon still lurks, scheming to enslave mankind. Only a single Guardian remains to stand against it, and humanity's survival hangs in the balance. Based on the graphic novel "Twilight of the Dark Master (Shihaisha no Tasogare)" (Shinshokan) by Saki Okuse.
