Following a long war, the Inorganics got hold of space as a whole. Even the great warriors of Zax from the Aqualoid planet couldn't defeat them. Rasa and Nam are the last generation of its dying people. In order to bring back freedom and its past glory, they go on a quest to find the sacred sword Shed. But in order to reach it, one must infiltrate the forbidden area : the Inorganics' temple.(Source: Black Box, translated)
