Trinity Blood

In the aftermath of Armageddon, humanity survives only to face a new dominant threat: vampires. Centuries of clashes have fractured the world into rival powers—the Methuselah aligned with the New Human Empire, and the human “Terrans” gathered under the Vatican Papal State. Even as both sides try to avoid open war, extremist factions such as the Rosenkreuz Order work to reignite conflict from the shadows.

To counter vampire-related terrorism, the Vatican forms the special AX unit under Cardinal Caterina Sforza. Among its agents is Abel Nightroad, an absent-minded yet kind priest whose calm demeanor gives way to lethal skill in battle. He’s partnered with Sister Esther Blanchett, a compassionate young nun carrying a painful past, and together they investigate a growing string of disturbances that hint at deeper conspiracies—ones that may force them to confront the wounds they’ve tried to leave behind.
