I have many fond memories with this series. I first read it in... middle? High? school, but the school library only had the first seven volumes, and I couldn't find the other volumes anywhere else. This was before I discovered sites like Batoto, and sleazier aggregate sites like OneManga, MangaFox/Here/Eden, other oldies. Anyways, years later, someone posted the rest online somewhere and after so long, I finally could read the rest of the series, and it was worth the wait
I highly suggest this for anyone looking for something new to read. The sequel is getting an anime adaptation, which I found kind of odd since they announced it around the same time the serialization started, and they never animated this series, but eh I'm not complaining
EDIT: Apparently it's actually about the original series. Man my info is WAY outdated
