Wholesale Seraph of the End, Vol. 33 by Takaya Kagami

[Viz] 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. Yuichiro and Mikaela desperately try to reach Sika Madu before Shinoa can consume him. But they have more foes to face. Meanwhile, Ferid is on the hunt, consuming vampires one at a time, and his next target is Krul Tepes. And while she should be able to stand against him on her own, Ferid has help from an unexpected ally—Guren.
