Two TPB omnibus books, nearly 1000 pages, collecting the entire YU+ME series, plus almost 100 pages of new content not found on the web, and 50 of those pages have not been seen in any previous edition, filling in some of the time spent wandering in search of Lia. (Due to an error, there are a couple missing pages, but the story makes sense without them, and you will also get the full PDF with every physical copy.)
The set weighs over 4 pounds. They are only sold in a set. This will never be printed again, so this is your only shot to get the story in print form.
