There was going to be a connection between Ayane and Christie but it was dropped when Ayane became more of a HeroineWhile Ayane was never depicted as flat out evil, her role was a bit more morally ambiguous namely on how Ayane was originally known as the one whom killed Helena's mother. Granted Christie has been revealed to be the one whom killed Helena's mother and was sent to kill Helena. However in Dead or Alive 2 when Helena tried to approach Ayane in rage accusing Ayane of killing her Mother, Ayane was pretty much mocking her questioning on whether if that was true. Granted Ayane wasn't flat out confirming it but she wasn't exactly denying it either. It seems oddly coincidental on how Ayane would make cover-up attempts over a murder she had nothing to do with. However by the time that happened Ayane was becoming more of a heroine especially during the modern Ninja Gaiden series. Which is the real reason why Ayane no longer had anything to do with the murder of Helena's Mother. I mean what? Where they worried about the potential implications of a teenager getting involved with a grown adult whom occasionally dabbles in nudism if Ayane and Christie did work together? (Granted I am sure certain fans wouldn't mind the "Potential Mental Imagery" there but still.)
Xtreme Beach Volleyball is real and Dead or Alive is fake.
Ninja Gaiden (Sigma and Sigma 2), DOA, and Volleyball is the past of the Halo Universe
Kokoro will not be returning in DOA 5The canon storyline will have her defeated before reaching Helena, thus she'll just have gotten her confidence beaten out of her and sent home to mummy.
The next game will REALLY push the boundaries of it's "M" Rating... No, not THAT way...Considering how Kasumi is now a guest star in Razor's Edge, and perfectly capable of committing the same bloodletting violence as Ryu and Ayane, this Troper thinks it's some Foreshadowing that DOA 6 will have scenes that are Bloodier and Gorier to match. Granted, there probably won't be any fatalities in any in-game matches, but the story mode can easily escalate in serious violence and drama onscreen, especially towards the climax. Bonus points if the other, non-ninja fighters get caught up in the whole mess in the worst way possible...
There will be a third DOA Extreme game but it will be one big Affectionate Parody of itself and its fanservice-laden World of Buxom nature.Naturally this will try to push the M-Rating as much as possible, in which this be more dialogue driven and the game will play up certain aspects like the Les Yay in the series a lot more. A lot of the characterization in the game will be due to which DOA girls will you pair with (in which some pairings will be a lot friendlier than others). Some character pairings will probably have little to no Les Yay (or any interaction at all) while others will play it as much as possible. (But any Ship Tease will most likely be Played for Laughs of course.) However, the fact that fans often like to pair the ladies with each-other (often due to fanservice) won't be the only thing that will be mocked, as character interactions can also lead to other gags such as the ladies trying to comment on various other parts of the series' storyline and try to understand them.
