Blood Circuit: The Vampire System – Synopsis

In a world where science has unlocked the secrets of evolution, Leon Kallus wakes up in a cold laboratory with no memory of how he got there. His body is no longer human—his eyes glow red, his strength is unnatural, and a mysterious Vampire System pulses in his mind, feeding him notifications like a game interface.

Dr. Vance, the scientist responsible for his transformation, claims that Leon is the first successful artificial vampire—a fusion of supernatural power and cutting-edge technology. But before he can demand answers, Leon is thrown into a brutal test of survival against relentless combat droids.

Hunted by secret organizations, feared by trueborn vampires, and trapped between humanity and something darker, Leon must master his evolving abilities before the system consumes him. In a world where blood is currency and power is stolen, one question lingers:

Is he the next step in evolution—or just another failed experiment?
