Each Volume came with several pre-order bonuses, including art books and special collectable trading cards that feature Class 78th. A customer would also be put in a special raffle with each pre-order purchase, which included a wall-scroll with the design of the anime's poster, a pillow featuring the face of Monokuma, and a Monokuma-themed umbrella.
The Volumes contain the original Japanese audio with English and German subtitles along with the German dubbing.
It is unknown if there's a Junko Enoshima or Mukuro Ikusaba card as its not listed with any of the releases, however it is listed as a set of 16 cards. So it is assumed they are included but not listed.
