In the future, interplanetary trade is doing well; however, this also opens up the possibility for pirates.  One of the most infamous ships is the mysterious Sol Bianca crewed by Janny (Captain), Feb, April, May and June.  The Sol Bianca has one ability that no other ship can do - enter warp without the use of a warp gate.  Good thing since everyone is after them!  After a stopover and getting some cargo (pirated, of course), they find a young stowaway, Rim Delapaz who is trying to get back to his occupied planet.  Being a war-torn planet, this does not interest the crew for the possibility of looting; however, Rim knows of a great treasure hidden on one of the planets.  Intrigued by the treasure, the crew agree to take Rim back.  However, the dictator of his planet has other ideas...

Can five young women take on the armed might of an entire solar system and win? If they're the treasure-hungry crew of the interstellar pirate ship Sol Bianca, the odds are just about even. Outfitted with a dazzling array of power armor, energy whips and the artifically intelligent, dimension-warping Sol Bianca herself, this quintet of larcenous ladies gives no quarter in their nonstop onslaught against a ruthless dictator who has the misfortune to possess a priceless treasure coveted by the bucaneering battle maids! The liberation of an entire civilization, the obliteration of a few dozen cities are purely incidental, as Janny, Feb, April, May and June cut a starship-sized swath of destruction towards the object of their money grubbing hearts' desire. 

2 part OAV.  The ending of the 2nd part clearly indicates that a
      3rd part was intended to be made, but none ever was.  There 
      was a script for "Part 4" which surfaces from time to time. 
      The script was an April Fools joke and is completely fake.  
      The 4th part doesn't exist...
