Seraph of the end. : Vampire reign. Volume 6
(Graphic Novel)

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's dream is near-impossible, given that vampires are seven times stronger than humans, and the only way to kill them is by mastering Cursed Gear, advanced demon-possessed weaponry. Not to mention that humanity's most elite Vampire Extermination Unit, the Moon Demon Company, wants nothing to do with Yuichiro unless he can prove he's willing to work in a team--which is the last thing he wants!

The only thing standing between humans and complete slavery to vampires is their tenacity and cursed gear. Yuichiro has the first in droves, but to increase the amount of power he can draw from the demon inside his cursed sword, he entera a coma-like state to thin the barrier between huma and demon. His power boost can come none too soon as the vampire queen reveals her plans to annihilate the human resistance.

Rated T+ for older teen.
