π THE WORLD OF OWARI NO SERAPH
ββββββββββββββββββββ
In 2012, a mysterious virus devastates humanity, killing most adults and leaving children as the primary survivors. Vampires emerge from underground and establish control over the remaining human population, treating humans as livestock for their blood. Years later, the Japanese Imperial Demon Army fights to reclaim the world using Cursed Gear and demonic contracts. Beneath the war between humans and vampires lies a much darker conspiracy involving ancient beings, forbidden experiments, and the Seraph of the End project.
