Flower of the Universe

Cato wasn't one for organic life forms. Her life was simple: she built disguised weapons, sold them to underground dealers, and filched food from the grand white castle she lived by.

She should have known that it wouldn't last.

Against her will, she's dragged into the intergalactic war and gets stuck assisting a group of amateur pilots.

Did she expect meet a princess that she can't seem to get her mind off of? No.
But, oh, would you look at that.
She did.
