The Japanese edition came with a flyer with a download code on the front and a link to an online survey card on the back. The DLC contains a Maria Rose costume from the Dead Or Alive series. The DLC is advertised by a sticker on the front.
Unlike the Switch version there was no Zero Tsukihami no Kamen Premium Box edition of the PS4 version, however the items could be purchased separately.
There were multiple pre-order items available from different stores. Copies pre-ordered from Gamecity included three bromide prints; KT SPOT Online Shop included an A4 clear file; Animate included three bagdes; AmiAmi included an acrylic keychain; ebten included a B3 tapestry; Neowing included a bookmark; Book-Off included a PET card; Melonboks included a different acrylic keychain; Yorozuya Shop Bikki Takarajima included a postcard; Rakuten Books included a microfiber cloth; and WonderGOO included a canvas art.
