In a post-apocalyptic world of vampires vs. humans, Yuichiro brings vengeance upon his vampire overlords!
After trumpets of the apocalypse proclaim the fall of humanity, vampires arise from the shadows to rule the earth. Yuichiro wants just one thing—to get revenge by killing each and every vampire.
Yuichiro and his friends head back to the Demon Army to prepare for the final battle. At the base, Kureto struggles to stave off Shikama Doji from controlling his body. But things quickly begin to fall apart when Shikama Doji also tries to take over Shinoa and Yuichiro! Will they be able to stop the possession? Or will they lose their bodies to the first progenitor?
