Seraph of the End, Vol. 30: Vampire Reign

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?
