Hm, I think ADV will release the box with the Volume 2 of the DVD.

I heard that some company was considering releasing boxes with second volumes instead of the first, so that people wouldn't have to spend so much on something they might end up not liking. But I couldn't remember what company that was. I guess it was ADV?
