Season 1 of Fate/Zero. While the picture shows everything that is in the box, it doesn't specify what exactly is inside. I recommend watching an unboxing video before buying it to get a good understanding of what you will be getting.

The Japanese blu-rays always come with more extras compared to North America and Europe releases, but this set along with the season 2 set, looks beautiful. The box has a beautiful illustration on the back, the blu-ray case is big and feels good to the touch, and each of the discs has a servant in the war and a few more extras.

I highly recommend it for the fans of the series.
