Thanks to a Japanese contact of mine, he has found a torrent for this DVD (2 DVDs actually, this girl was so popular, they released 2 DVDs in one)! Rejoice and commence fappage!

And yes, the video itself is as good as the DVD cover! The encoded video is split into several parts because that's how the original DVD was structured.

Download the .torrent file here (use IE or a different web browser because this site is buggy with firefox) and start your bittorrent client: http://www6.mimima.com/link.php?ref=HvMInVUQ8c
