Story
Planet Toraidoru has fallen to the attack of a mysterious enemy. Something is needed to oppose the masses of fighter planes which appear, one after another, from the enormous enemy mother ship. The most up-to-date weapon must be utilized: High Movement Variable Aggressive System VOLGUARD.

Volguard is composed of three separate machines which unite to take the form of a gigantic robot. In robot form, Volguard has access to the Hyper Canon and the Active Barrier. It is a history-making system of aggression.

Due to it's extreme energy consumption, the wear brought on by a long battle, and the low productivity due to the complexity of it's structure, maintenance of the system has become a difficult problem. However, its attack power and defensive power is the only thing that can quickly accomplish the immense task.

It is your mission to pilot the Volguard, and drive away the enemy's enormous mother ship.
