Trinity Blood: Genesis (2006)

The world has been rebuilt from the Armageddon 500 years previous, and it seems that peace and harmony reign - Beneath the surface, the forces of darkness and the alliances of the Vatican church still hold on to ancient grudges. Vampires, once believed extinct, have risen again to curse the daylight, and the brave defenders of humanity, now armed with advanced weaponry, hunt them at every turn. But the new war is not like the old-intrigue and espionage are now the norm. The enemy is within-infiltrated into the deepest levels of the papal bureaucracy and unlikely political alliances have changed the landscape, blurring the battle lines between the living and the undead.
