In 2029 Tokyo, dinosaurs walk among us. Thought extinct since the asteroid impact, they survived by passing their DNA into humanity through interbreeding, living as ordinary people while hunting those around them. Most of humanity remains oblivious to the predators in their midst. A secret ninja organization holds the line. Armed with Ryugesho, a mysterious pigment carrying ancient memories, these warriors awaken dinosaur powers within themselves to fight back. When the hidden dinosaurs begin a campaign to wipe out humankind, the ninjas rise to stop them. What unfolds is an action-driven shadow war fought in plain sight, with the survival of two species at stake.
