Looking through my library, it looks like the first two volumes was done by one guy, who then dropped it. And then volume 3 had a group that picked it up and was settling in. And then that same group keeps with it, the girls get more casual speech consistently and details get more accurate.
And then by Volume 6, the quality of the scans EXPLODES upward in quality. What used to be 990x1400 becomes 1670x2400, then 2994x4304 image files.
