Juusou Kikou Dancougar Nova

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.
