“Raizo is alive”
The entire arc, there was tension about the minks finding out the Strawhats were pirates, just like Kaidou’s beast pirates, and that they were connected to Raizo, the cause of their suffering.
Turns out, that the minks preferred having their isolated race being slaughtered just to have a stranger protected, whom later we find out, the only connection between Zou’s leaders and Raizo, was that both were Oden’s cocksuckers.
This started a sequence of never ending conveniences for the strawhats, culminating with them getting bullshit power ups, the nika fruit retcon, and alliance members losing their personalities, just to favour Luffy’s crowning as a Yonkou, and to avoid any minuscule complication in a pirate alliance, who were supposed to be risky.
