I've always really loved the other two Celtrance Lucky Star doujins that have been circulating the interwebs (only one other of which appears to be on the site at the moment), so it's a big pleasure to see a new work of theirs uploaded to the reader.
I really wish some of the mysteriously missing ones (such as the sequel to Aogeki Murasaki Mamoru!) would be found and scanned one day. That'd be nice to see.
