@Storm chaser, here you go lol I cant share any links to support my post nor do I believe this to be 100% true, BUT !! I guess its worth the mention to see what you all think & maybe your criticism can clear this theory up bit more. Ok, So maybe Kuina didnt die "falling down the stairs" .. Maybe she left to follow her dreams. Remember that time when Dragon & Ivankov docked on the island Zoro & Kuina were training on for a few days & Kuina was going on about how she cant be the best because she was female? Would Oda do that for nothing ? With Kuina already being the strongest student maybe she needed to move on to become stronger? She died (disappeared) the next morning after her & Zoro made a promise that 1 of them would become the best swordsman. Ivankovs the type to help people & their desires & since they were on that island chances are Kuina left with Ivankov & later became a male. The revolutionaries must of been in contact with Koshiro (Dojo Master) at some point & may even have had some type of conversation ?? We can see in the chapter (sorry idk what chapter) that when dragon sets sail off the island that he was questioned "Dragon your late, how long will you keep us waiting", meaning something held him up longer than expected & Im sure Ivankov was not on the ship. Kuina also questioned about "the person with the huge face" ? Also Koshiro is the original owner (or his family) of the Wado Ichimonji, which Zoro inherited so maybe Koshiro is more important than we think ? (this last part im not too sure about) I havent looked into this properly to the best of my ability but if yous know anything that is connected to this please share. Hope you enjoyed anyway, -Mosshead.
