See my notes from the series comment thread:
Doing a bit of cleanup for chapter 1. The original upload by VicPhant was the better volume release by Pretty Anon, except that he deleted a couple of their B&W spread pages and replaced them with the color pages from the lower-quality Underdog magazine chapter.
I'm uploading what I have from Madokami, which had two alternatives:
1. The original Underdog release, with the addition of a few nice extra pages from the volume
2. The Pretty Anon release, with the Underdog color pages added in alongside the B&W versions, plus the same extra volume pages.
Overall nothing big, but a few pages added for posterity that were missing before.
