The way Oda mishandled Toki really disappointed the shit out of me as well…we get to meet an actual living person from the Void Century who has the power to leap AND send others through time, in the arc where the central mysteries of the series have come much closer to the forefront than ever before, and not only is she killed to advance several male characters’ stories, we have yet to get any indication that her own backstory is forthcoming. Still holding out hope that she DIDN’T actually die (which would still be a cop out at this point) and can be fleshed out more before this arc is over, but I’m not holding my breath while I wait
