The way it was executed in the chapter the execution of the Toki appearance was not as bad as I thought. It can actually turn into something interesting.
It seems like Toki beamed herself from the burning Oden castle to this exact moment.
It's possible now that she beams all of the scabbards to the future again to keep them safe.
That is, if she has still enaugh strength left. She looks really exhausted atm.
If Oda executes this this well and gives a good explanation on why she beamed herself forward AGAIN, despide having decided to die with Oden and to not keep 'running away' to the future anymore it can become a good thing and may give more relevance to Toki as character.
Until now she's rather bland and , except being the super-loyal wife to Oden, there's not much personality to her.
I hope Oda will develop her more and I'm especially curious about her interactins with the others: Wano characters who have seen her 'die' in the past, the scabbards, the staw hats and especially her children.
