Ryokugyo is now in the ninja nation of Wano looking for the smoke. Sanji has the strongest CoO amongst everyone so will sense him coming before anyone else
Aramaki will be alluded to being Sanji’s opponent at some point in the series. Through a direct clash in Wano sizing each other up or strong parallels. Kizaru will still be his final opponent tho
If my theory is completely wrong then it will be Law fighting him because he’s not going nowhere anytime soon in regards to screentime.
Sakazuki - Luffy
Kizaru - Sanji
Fujitora - Zoro
Ryokugyo - Law
