Sol Bianca

Sol Bianca (ソルビアンカ, Sorubianka) is a two-volume OVA series released in 1990 and 1991 by director Katsuhito Akiyama in association with AIC, followed by a remake OVA titled Sol Bianca: The Legacy (太陽の船 ソルビアンカ)

Plot
Five female pirates pilot the Sol Bianca, a starship with a higher level of technology than any other known. They sail across the universe seeking out riches until they come across a stowaway hiding himself aboard the ship during a raid, where they learn of the ultimate treasure: the Gnosis, an artifact reputedly from old Earth itself. Together, they accept the stowaway's quest to save the one he loves and seek revenge against those that have wronged them.

Unfortunately for them, the Gnosis happens to be in the hands of Emperor Batros, the brutal ruler of the planet Tres who is executing great numbers of enemies, real or speculated, as a result of his military occupation of the neighboring planet Uno. Armed with a little luck, a sniper gun that can shoot from orbit, and a technologically advanced ship, the crew of the Sol Bianca are about to make a run for the greatest prize of all.
