Yeah, so then stop calling Luffy 'jesus' too, lol. If Luffy is indeed related to JB or Nika, and if their blood was anything special all his descendants would also be special but here we have Luffy hundreds of years later.
The problem is that Luffy has a bunch of actual prophecies about what he is going to happen, just like Jesus and Naruto
you can't see the difference?
nobody IN the story is saying there's a prophecy about another Shimotsuki doing the exact same thing Ryuma did, there's nothing about that, if there was people would be hyped as fuck to find a Shimotsuki to kill Kaido.
Luffy is the one destined / full of prophecies, just like Jesus, to do something.
