20 years ago the wife of Oden proclaimed a curse on Orochi, who interpreted it as a prophecy that nine samurai would kill him in revenge and open Wano’s borders in 20 years.
Recently in Wano, Kin’emon revealed that Momonosuke, Kanjuro, Raizo, Kiku, and himself have time traveled 20 years from the past.
So Oden’s wife specifically told Orochi that 9 shadows will be cast on a moonlit night and kill him in 20 years. The thing is she only sent 5 people into the future. The last remaining four could be Luffy, Zoro, Law, and someone else. But what I think she was talking about was Zoro’s Asura.
We know the Asura has 9 hands and appear like 9 shadows. Also Oda wouldn’t just reveal that Orochi uses a 2 swords style just like that for no reason. I think it heavily implies Zoro will fight him because he uses 3 swords style. Orochi will think it’s the 9 samurais that have come to kill him. But he will be defeated by Zoro’s Asura which he is not expecting at all but it fulfills the prophecy in the end.
“You are like the moon who knows not of the dawn. If there’s one ardent wish that can be fulfilled, then it shall be the one where Nine Shadows are cast, woven together through 20 years of Moonlit Nights. Only then shall you know the radiance of The Dawn”
I can just imagine the clever illustration of Zoro’s Asura Form, standing above Kurozumi Orochi while the Full moon appears from behind the Clouds, casting the shadows of 9 swords upon him.
