Kozuki Toki, Lady of the Kozuki Family and Wife of Kozuki Oden
She’s the one who sent Kin’emon, Momonosuke, Raizo, Kanjuro, and Kiku to the future using the Toki Toki no mi as she did to herself. (When the fuck was she born originally? Void Century??)
I find the lack of ability to go backwards in time a great way to keep this fruit from being OP. It keeps it more along the lines of a curse or magic like the abilities of Kin’emon, Kanjuro, and Tama.
The only thing that sounds really messed up is the possibility that she didn’t send her daughter Hiyori to the future separately (I have ideas about that 👀) and let her die alongside herself in the fire.
