Read this AFTER Hoshi no Yakata, even though this is a prequel to HnY. Hmmm ok so I just read this, and whilst it's interesting to know Master's backstory as a slave, I dunno, I just couldn't get into it for some reason...
Prequel to 'Midara na Sasayaki'. 3.5 stars, mainly for the art, as the story itself was nothing special.
