forget about Zoro not getting ZKK, do you guys really think would be satisfactory to watch Momo just grow the fuck up by a Devil Fruit and defeat Kaido out of nowhere?
hell, make Shinobu give 1 year to Luffy or Zoro and they turn into Yonkou level by this logic.
This devil fruit is absolutely BS.
Even better, just turn Kaido into a fucking old man that can't even walk anymore.
for fuck sake.
