Someone at Deadforg Torrents put this up just a little while ago…
http://www.deadfrog.info/index.php?action=…ry&entryid=1616 OP manga volumes 1-3
http://www.deadfrog.info/index.php?action=…ry&entryid=1620 OP manga volumes 4-15
I don't know the exact contents, but I'm dowloading 1-3 to check. It seems that no one is seeding, so…
Details comming as soon as it's done.
EDIT: I don't know how long this torrent will last, since Deadfrog tries its best to avoid torrenting liscened work.
