So, I now have the Shana set - on the plus side, it is actually a new set, so all four discs housed in one regular sized DVD case - saving shelf space.
But the downside - I think this is probably MVM's worst looking cover art in ages; that 'complete series' font tacked on the front looks really cheap and the duplicated text on the back is just shocking. I understand mistakes happen, but tbh this one takes it to new levels.
