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 Mika finally know the truth about their pasts and now have to figure out how to handle this big revelation. Both are tempted to sacrifice themselves for the sake of the other if it means saving the world, but they come to the conclusion that there must be another way. And that other way starts with the vampires and Sika Madu himself. Meanwhile, Shinoa has her own plan to rescue Yuichiro while Ferid and Guren are up to no good with their own agendas.
