The story is set in a world where dinosaurs have been resurrected through advanced genetic engineering, leading to a society where humans and dinosaurs coexist. The narrative centers on a young protagonist named Ryuta, who becomes entangled in a high-stakes conflict involving powerful corporations, rogue scientists, and ancient reptilian forces.

Ryuta, an ordinary teenager, discovers a mysterious device that allows him to communicate with and control dinosaurs. This ability draws the attention of a megacorporation known as DinoTech, which seeks to exploit his newfound power for their own gain. DinoTech aims to dominate the world by weaponizing dinosaurs, and Ryuta becomes a key figure in their plans. However, he is unwilling to comply, leading to a series of confrontations that escalate into a global struggle.

As the story progresses, Ryuta allies with a group of rebels who oppose DinoTech's oppressive agenda. Among them is Akira, a skilled fighter with a personal vendetta against the corporation, and Mei, a brilliant scientist who provides technical support and insight into the origins of the dinosaur resurrection project.
