Seraph of the End, Vol. 13: Vampire Reign (13)

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 successfully coerces Shinoa Squad and Mika into joining him and Crowley on a field trip to Osaka. According to Ferid, the purpose of the trip is to see the truth behind the Calamity that ended the world--ground zero of the apocalypse. But not all is as it seems, as vampire nobles from across the world are also converging on Osaka.
