Update: Game Director Yohei Shimbori told 4Gamer (via Siliconera) that Tecmo Koei plans to add Marie Rose to all versions of DOA5 Ultimate via an update.
Dead or Alive 5 Ultimate: Arcade, the Japan-exclusive arcade port of Team Ninja's latest brawler, is piling another character on top of its already-stacked roster. Lolita fasionista Marie Rose, along with the other 862 characters* in the game, is briefly teased in the trailer above.
Japanese arcades get DOA 5 Ultimate: Arcade some time this winter. Tecmo Koei has not announced the arcade version for other territories, though a post on Facebook says that despite this being an exclusive to Japan, "we haven't forgotten about our overseas fighters" and that Tecmo Koei will provide "more information in the near future."
*There aren't 862 characters in DOA 5 Ultimate: Arcade, despite the fact that it totally seems that way. In reality, there are 30 characters to choose from in DOA 5 Ultimate: Arcade.
