Hum sorry? Why does it need to be the end of the story for titles to be given? What kind of bullshit is that?
"Hey guys Whitebeard died, who's the next in line for the tittle of WSM?
"No we can't give that away yet, because Luffy needs to reach Raftel first"
What kind of excuse is that
tittles pass instantly bro, there's no minimal time requirement
