So here’s a shot of the retainers we know were sent to the future. From right to left. Kiku, Kanjuro, Kin’emon, Raizo, and a mystery fifth person

And the fifth person is again shown (no face shown thanks to the kasa they are wearing) bowing to Lady Toki along with the rest of the retainers

And yet when Raizo, Kanjuro, Kin’emon, Kiku, and Momonosuke appear in Wano 20 years later, the fifth retainer is absent

Now here’s my thought. The fifth retainer was also sent forward but not as far as the others. The Kozuki siblings were split up. Lady Toki wouldn’t put Hiyori through a fiery death at such a young age. Not when she could also send her to the future like Momonosuke.

Lady Toki sent Hiyori to the future alongside the fifth retainer who I believe is Tenguyama Hitetsu.

When he learned who Luffy was he stated to be waiting for someone

I believe he’s waiting for the prophecy of the 9 scabbards or some separate order he received from Lady Toki.

Or maybe he’s waiting for orders from Kin’emon.

Who knows ¯_(ツ)_/¯

PS-If you want to see who I believe Hiyori is, see this post.
