Quality of the scans drops from ch.2-5 but picks up again throughout ch.5-8.
The chapters seems to be based off the general timeline of the anime series. So the stories are not exactly the same as the anime and may occur between episodes etc.
@raven_freak In terms of presentation yes; it's very faithful to the feel of the anime. In terms of the story presented... sort of; some chapters do replicate episodes of the anime, while other chapters reference and expand upon the anime, assuming that the reader has watched it. The intent seems to be to supplement the anime without being totally inaccessible to folks who haven't see it.
