Late for his new posting to the White Nuts team, JJ finds himself caught in an attack by the invading forces of Noza. The rest of his team is sent to stop the attack using a set of three mysterious guns named "Zillion."

JJ learns that the Zillion guns, being the product of a mysterious civilization, cannot be analyzed or duplicated by human science. Noza launches an attack on the energy control center in Gloria City.

Noza has plans to destroy the capital, Hope City, using a giant energy cannon that they developed. The White Nuts must destroy the energy cannon to save the capital, but the enemy's defenses are formidable.

Baron Ricks, supreme commander of the Noza forces, runs a computer analysis of the White Nuts, and learns that Zillion is the secret to their power. Ricks attacks an important base to draw out the White Nuts.

The Maris Force's top weapons lab comes under Nozan attack. The White Nuts are ordered in to rescue a cabinet minister that is trapped in the lab, a mission that leads to strife between Apple and JJ.

A secret Nozan weapons factory is discovered in a snowbound mountain gorge. The White Nuts, equipped with new vehicles, are sent in to strike, but are left in the lurch when their support unit is ordered elsewhere.
