Well she is the new face of DOA so she gonna have the most outfits, oh and for the season pass costumes coming up in the next few months at least one of the will have Ayane's Fatal Frame outfit in it.
You don't need to buy the costumes for that, just get the catalogue for it and the AI will show up in those outfits at times when picked Random or in Team battle.
Played DOA1 on PS, bought it as was into fighting games, just got interested since then, I've owned all games at some point apart from 4 which I rented for a weekend and never really got into. Been a more active and bigger fan since 5.
Since Naotora and the new update came out mine has actually improved in how long it takes, now I only have to wait until halfway through the 2nd message on the scroll bar before game it loaded.
I shall be getting that Ayane figure the second it becomes available. I've got about 15 or so DOA figures on my shelve at the moment but they will be in a display case along with other DOA material when I get my own place.
