Black Blood Brothers - S01

Black Bloods and Red Bloods, vampires and humans. Even with their differences, the two races once fought side by side in a crusade against a powerful enemy. Ten years later, the vampire war hero Jirou Mochizuki, called the "Silver Blade," travels with his younger brother Kotarou to the Special Zone, a safe haven where vampires and humans live together in peace. But their journey is suddenly threatened when a conflict breaks out between vampire migrants and human forces from the Special Zone. As a conspiracy grows from an old enemy, Jirou will need help from his new ally, Mimiko "Compromiser" Katsuragi, and the power of his ancient bloodline to protect what he treasures most.
