Tokyo, 2029. Dinosaurs, long believed extinct after the asteroid impact, have secretly survived by interbreeding with humans, passing their DNA into the human gene pool. Now they live hidden among ordinary people, preying on humanity while remaining undetected. Against this hidden threat stands a covert order of ninjas who wield Ryugesho, a special pigment infused with ancient memories. By applying this mysterious pigment to their skin, these ninjas awaken the latent dinosaur powers within themselves, gaining the strength and abilities of the prehistoric predators they hunt. As the dinosaurs launch a campaign to wipe out humankind, the ninjas rise to stop them, igniting a battle for the survival of two species. The story unfolds in a neon-drenched, futuristic Tokyo where the lines between ancient and modern blur, and the conflict between humanity and its hidden predators drives a narrative of secrecy, survival, and the cost of wielding forgotten power.
