MARS RED - S01

In 1923, Tokyo faces a surge of vampires fueled by the black market trade of "Ascra," a synthetic blood substitute. To combat the threat, Lieutenant General Sounosuke Nakajima orders the formation of Code Zero, a secret military unit composed of vampires tasked with hunting their own kind. Colonel Yoshinobu Maeda leads the unit under intense scrutiny, racing to trace the Ascra supply and eliminate rogue vampires before public backlash shuts them down. Meanwhile, the vampire soldiers grapple with their transformed selves, caught between their fading humanity and emerging supernatural instincts. As tensions rise, Code Zero must navigate the chaos-before they succumb to the very darkness they were created to fight.
