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. Ferid Bathory and Krul Tepes have been captured by the other vampire nobles and the members of Shinoa Squad are forced to bide their time while the two vampires are sentenced to days of exposure torture.
