In this world, there are beings known as Blood Knights. They are not vampires as humans understand them, but “heroes” once hailed as saviors.
At first, the Blood Knights used their extraordinary strength to protect humanity and fend off unknown threats. People lived in peace, praising their deeds and viewing them as divine protection.
But that peace did not last. Strange disappearances and mutilated corpses began appearing one after another, and people gradually realized something was wrong: these “heroes” were monsters who fed on human flesh and blood.
To the Blood Knights, humans were nothing more than helpless livestock waiting to be slaughtered. Their supposed “protection” was merely a way to make it easier to harvest food.
Even more chilling, when not transformed, Blood Knights looked almost exactly like humans: warm skin, natural expressions, and the ability to live and talk like ordinary people. There was no way to tell them apart.
This threat lurking right beside them plunged the world into panic, with everyone fearing for their safety. Adoration gave way to deep-seated terror and hatred.
To survive, humanity established an official extermination organization: the Blood Hunters. This is a fan work combining Kamen Rider and Tokyo Ghoul.
