Seraph of the End

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. The only thing standing between humans and complete subjugation to vampires is sheer tenacity and Cursed Gear. Yuichiro has the first in spades, but to increase the amount of power he can draw from the demon inside his cursed sword, he enters a coma-like state to thin the barrier between human and demon. His power upgrade can come none too soon, as the vampire queen reveals her plans to annihilate the human resistance and claim true dominion over Japan.
