Now that we got a confirmation about what happens to the DFs when the user dies, I wonder if we're gonna learn about who used the known DFs beforehand. Like who happened to have the gomu gomu no mi before luffy?! I think, Oda opened a new possible story-line with this. At least I hope we learn more about the past of the OP world.
Or who will use them afterwards. I hope the Yami Yami will be eaten by the "next Luffy".@EvoWarrior5:
We've known this for a long time already. How did this chapter change anything?
The thing just is, only Luffy did not know yet. But we as fans have had it confirmed since long.
At least, I think we've known it for long. But we knew for sure after Shinokuni in Punk Hazard.
No, we didn't. It was the most likely conclusion, but not really confirmed.
