Earlier on during the Japanese release of Hatsune Miku: Project DIVA X, SEGA included an exclusive air hostess module (named “CA Style A”) for Hatsune Miku as a preorder bonus for the game. A variation of the module, named “CA Style 39”, was included with Famitsu. These two modules were part of a deal with Japanese airline company Air Do, and they will now be made available for free for both the PS4 and PS Vita version in Japan on August 25, the same day as the PS4 version is released.
Whether or not this DLC will make it to the West remains to be seen, since the Air Do partnership is not particularly relevant outside of Japan. At this point, there’s no news yet regarding Hatsune Miku: Project DIVA X DLC for the West. But that’s probably only a matter of time.
