You can download Naotora Ii for Dead or Alive 5: Last Round, at least on Xbox One. The PlayStation Store has not yet updated, but she will be available the moment it does. The game updated alongside this release, bringing the Azuchi stage to everyone for free. The character is $5.99 alone or $11.99 bundled with the extra debut costumes, both of which are included free in the season pass 3.
Naotora Ii attacks primarily with kicks as she does in Samurai Warriors. Most of her moves in DOA look like they were translated directly from Samurai Warriors 4.
She has been added to the tag team list, however, disappointingly, she has no unique attributes with any of the other characters. Team NINJA published a debut trailer and combo trailer today. We also have provided a gameplay sample of Naotora and the Azuchi stage.
