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.

Given the choice of two extremes, Yu picks a third option--instead of following Guren or the First's plans, he'll forge his own path. He takes Mika and leaves Shinoa squad, vowing to resurrect everybody! But to do that, the two first have to delve into their pasts and learn what's really going on. And to make that dive, Yu's going to need a lot of energy, but provisions are scarce. The two resort to devious means to get what they require--but if it's for the sake of saving the world, it may be worth it.
