Oda is clearly trying to hide the identity of this mysterious woman, and these are the sorts of "breadcrumbs" that he loves to put out for fans. I would be willing to bet she comes up again (eventually), and probably relatively soon (since I doubt she will be a powerhouse necessary for the second half of the Wano Kuni arc). The main reason for this is that Oda could have simply had Zoro lost and randomly be found by the patrol guards. He not only is purposefully hiding her face, but also went out of his way to create the Sanji gag (which I think will be a running gag for the nakama to not go with Luffy to WCI). So who exactly is this lady? My bet is on a relative, and probably older sister of Tama. Here's a few context points that make me think this: Amigasa Village is quite remote, so chances are there is not much else in the surrounding area. This lady had a purpose to be in the area. We know that it is Tama's birthday, so the reason to go out to this remote area could be tied to Tama's birthday. The mystery lady almost immediately disappears in the short moments of Luffy and Zoro catching up (i.e. she's pretty damn fast considering the wasteland is completely wide open). Something that ties all of these points together is that she is Tama's older sister, who is a kunoichi also loyal to the Kouzuki family. Her loyalty is why she has the responsibility to go out and be a spy (or at least blend in with the majority of loyalist to the Shogun). This is why she cannot fight openly since it would blow her cover. Although she was planning to visit her little sister (more on this a bit later), Zoro and Luffy completely destroyed her plans. She is probably watching from the forest, but Hawkins' defeat will mean someone stronger will be sent to investigate, and she won't be sticking around for that level of danger. This is where Oda can delay her real introduction until the alliance starts to gather/plan their initial attack. The large age gap may seem unlikely by current societal norms. However, this wasn't that uncommon (even when I was a kid it still happened) in that parenthood is/was highly planned/responsible by the majority of the population. Thus, especially in hard times (the entire existence of Amigasa Village as we know so far), child-birthing was only when there were resources to provide and raise the child. So historically, it was common to have large age gaps between children in Japan back in the day with the older sibling(s) trained to raise their younger siblings while the parents did the farming/household chores. In typical Oda fashion, destiny/fate will bring them all together with a funny little scene of Luffy/Zoro being crazy reckless and making a big scene to ruin her plans. Being in such a rush, she may not have seen Tama on top of the doggy. Even if she does see Tama, the risk of Drake/Jack coming will force her to flee. Think that covers the major aspects...any counter-theories/thoughts?
