Two immortals who should've stayed brothers end up swinging at each other instead. The tragedy isn't that they fight, it's that they remember exactly what they're destroying when they do. Eight centuries of friendship dies in real time, and the show makes you feel the weight of every single year.

Set 820 years before the events of Noblesse, this single OVA opens as Mujaka, lord of the werewolves, comes to visit his friend Raizel, the Noblesse, after a long journey. Mujaka had left his clan behind to travel with Ashleen, a girl orphaned by a human war, hoping to give her a happy life. In his absence, werewolves disgusted by his compassion stir up more wars against humans, and Maduk meddles in one of them. A powerful secret organization, the Union, feeds Mujaka false information to steer him, and his rage turns toward humanity. Raizel and Mujaka are drawn into a tragic, desperate fight that sets their friendship aside.
