I just took the White Star plunge the day before this PDF came out because of all of the buzz about it and the secondary material coming out. Star Sailors is just the type of material I want to see. I does what it says it does: introduces galactic magical girls and genre tropes into White Star. There really isn't anything negative to say on my end. The author says he wants to produce more anime themed White Star supplements. Star Sailors goes alone way, especially if mixed with Ruins and Ronin. I suggest a mecha genre supplement.
