This story is pretty good! I guess it's rated poorly because of the poor scanlation quality and translations. I had to google a bit to find some good ones. But yes if you are planning to read on MD, wait for some good quality scans & tl that do justice to the story.
Yes there are some inconsistencies if you read early on, but I find them being integrated/explained into the story in the following arcs. I guess this type of manga you do need to read in a complete arc, rather than chapter wise. The author does have a central plot going on, and hopefully he will tie up all loose ends in the upcoming arcs.
PS: Trash, slimline and oneshot scans are good, rest are 'speed' scans
