#finally something interesting

Everyone’s probably wondering that now... by this point, I think it’s pretty clear that she wasn’t sent along with Momonosuke and the others. If she had then surely they would’ve mentioned it... one theory is that she died along with her mother, but I highly doubt it. If that had happened, what would the point of including her in to the story have been? That said, I think there are three possibilities:

1: Hiyori was sent to the future, but arrived before the others and could now be older and she could be anywhere, like gathering allies or working for Kaido undercover.

2: Hiyori was sent to the future, further than the others. Perhaps she will appear in the middle of the battle, or perhaps in some other arc entirely.

3: For one reason or the other, Hiyori wasn’t sent to the future and is still in Wano, having aged 20 years. Again, perhaps she’s working for Kaido, either undercover or forced like Viola was in Dressrosa, or perhaps she’s gathering a rebel army... or just simply hiding somewhere, living as a normal citizen.
