It is 199X A.D. In Kushiro, Hokkaido, three bodies of Dragonite appear. Possessing overwhelming destructive force, they attack the city. They also awaken the evil Jashin Drago from the holy seal he was trapped in. 200 years ago, Drago was trapped in the seal by a holy warrior with the tattooed mark of the Liger. Assuming that the warrior is dead, Drago and Empress Zara are free to conquer the Earth using their army of biomechanical beasts. Even the Japan Self-Defense Forces are no match for the Dragonites' awesome power. One of the people fleeing is the protagonist, a milquetoast 16 year old boy named Ken Taiga. Unbeknownst to the Dragonites, Ken realizes that he is the descendant of the Liger warrior! In a burst of anger, Ken's Liger birthmark appears, and he rises his palm into the air, shouting the henshin command, "LIGER!!!", which then covers him in demonic long-haired biomechanical armor. Ken transforms into Jushin Liger to fight the evil forces of the Dragonite!

The new series is set in a near-future world where the boundary between human being and AI is vague. A rapid biological evolution, similar to "Cambrian Explosion," is caused by one incident. This incident turns into the genesis of a new jostle for supremacy, and the influence of the evolution goes beyond biological framework and spreads to various kinds of materials and technologies. The era of massive evolution involving diverse existences, such as human, machines, and biotechnologies, is coming. Characters fight an existential war in such a world.

In the 22nd century, there are no longer any world wide wars. Instead, small scale wars break out all over the Earth. Meanwhile, a large robot appears who protects the weak. It is called "Dancougar Nova". Some even call it God. However, no one knows the reason for its existence - not even its pilots. Then, another robot, beyond anyone's expectations, reveals itself as the true enemy and begins its attack on the Earth. Dancougar Nova retaliates against this enemy with a power that was kept secret until now. Will Dancougar Nova be able to save the Earth? The prelude to this explosive confrontation rings out.
