Darren Wagner has guarded his purity for a billion years, secretly building world-destroying power while hiding near the Hexalo Guild, waiting for a natural spirit to lose its purity. But when a saintess disguised as a maid stumbles into his fate—and even her mother is dragged in—everything changes. At the grand ceremony, his identity is exposed, demons strike, and his “pet chicken” suddenly transforms into an ancient phoenix, killing the demon lord in one blow and shocking all.

In 2287, humanity is extinct, and Earth belongs to vampires and werewolves locked in a century-old war. When vampire archivist Veyra discovers a preserved human skeleton and a forbidden biology textbook, she begins questioning everything her kind believes about the past. Meanwhile, werewolf scout leader Elon learns that his sacred symbols are actually relics of human civilization. Their investigations lead them to the Dead Zone, where they uncover a terrifying truth: humanity vanished in a single, unexplained moment. Hunted as heretics, Veyra and Elon must join forces with a mysterious AI to uncover the truth behind humanity's extinction before history repeats itself.
