Trinity Blood

In a post-apocalyptic future, humans and vampires remain locked in a war that began with Armageddon. The Terrans and the Methuselah are divided between the Vatican and the New Human Empire, though many on both sides hope for peaceful coexistence. The vampire extremists of the Rosenkreuz Orden work to thwart that hope by manipulating the two factions and turning them against each other. To oppose them, the Vatican’s special operations group AX, led by Cardinal Caterina, must use every means at its disposal—including a vampire who feeds on the blood of other vampires.
