Seraph of the End, Vol. 30

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. Yu and Mikaela dive into the past in search of their oldest memories, and they pop out in a shocking time well before the birth of humanity…when dinosaurs roamed the earth! They continue on and run into an angel that looks suspiciously like Mikaela, who leads them to a mythical city with an enormous tower that extends into the heavens. What sort of mysteries will they encounter there?
