The set includes a SteelBook, twelve character cards, a folded map, and an art book. The displayed art board and keychain are retailer preorder bonuses.
Retailer bonuses are separate from the official set
This is the Japanese deluxe collector's edition. First, look at the art board beside it: the four protagonists stand before the arena on slightly matte stock, a size larger than an ordinary postcard.
The art board and keychain are Amazon Japan preorder bonuses. They are retailer gifts, separate from the official deluxe set. If you want them, check that retailer's preorder conditions rather than assuming everything displayed together comes inside the box.
Character cards and the folded world map
The box and manual are in Japanese; in-game language follows the console's system language. The SteelBook is a collectible case for the game card. The next pleasant surprise is the character cards: twelve in total, ready to take out and inspect individually.
Unfolding the large sheet reveals a complete world map of Dagda.
Art-book turnarounds and environment designs
The original art book is a weighty hardcover. First come full-body illustrations and three-view turnarounds for 
Cai, 
Dietrich, 
Theodora, and 
Leda, showing front, side, and back views with notes on clothing details.
Designs easy to miss during gameplay can be studied at leisure here. Later pages show concept art for the capital's buildings, the arena interior, and regional environments. Colors are rich, and the slightly matte paper produces little glare while browsing.
