In the year 2545, an experiment gone wrong puts test pilot David Jance through the center of the galaxy and into another universe, which ends up in the middle of life and death struggle against the armies of GRIP, led by Dark Star.

It is the year 86 of the New Galaxy. In a binary star system somewhere in space, there is a special area called Zone Subsqui, which converged all the races of the galaxy to form a new civilization. However, alongside the progress, crime flourished, and the Organization of Evil became the scourge of the new order, exhibiting powers above those of the space authorities. It was therefore decided that, to combat the Organization of Evil, a group composed of brilliant scientists and brave warriors would be created, known as Gorilla Force.—TVTropes
