Japanese
未知のウイルスにより人類は壊滅、子供だけが生き残り、地下都市で吸血鬼に支配されていた. 勝気な少年・百夜優一郎は仲間たちの犠牲のもと、ただ一人脱出に成功、復讐を誓う. 優一郎が見た新しい地上の世界とは!?

English
''After trumpets of the apocalypse proclaim the fall of humanity, vampires arise from the shadows to rule the earth. Yūichirō wants just one thing—to get revenge by killing each and every vampire.''

Yūichirō's dream of killing all vampires 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 Yūichirō unless he can prove he's willing to work in a team—which is the last thing he wants!

Cover Details
Volume one's cover features Yūichirō Hyakuya at his present age, where he has dark hair and green eyes. Having escaped the underground vampire city that he lived in as a child in chapter 1, Yu is now dressed in the Japanese Imperial Demon Army uniform first seen four years later in chapter 2. This is black overall with green features, particularly at the front of his cap, and the inside of his raised collar, then the interior of the cape he wears as well. A belt buckle around Yu's waist appears green tinged within the center of the grey belt that it is situated. Yu is armed with a katana like sword, which has a green shine emanating from it.

It is likely a scene of Yu working as a guard tasked with patrolling the outside world where Horsemen of the Apocalypse were active. The setting resembles a ruined cityscape with foliage on the side of cracked buildings, and a tree visible. The chain link fencing behind Yu is also covered in vine like leaves in areas. This fence is situated to the left of Yu, and below him on the right.
