If Sandai is getting replaced, Wano was perfect for it especially with Nidai.
Zoro's Sandai and Nasu's Shodai has already clashed.
Sandai isn't getting replaced.
Well, you have to pick one, because Zoro can not become a Top Conqueror without being chosen by a '' Naturally born '' Supreme Grade Blade..
Ryuma was the absolute king with an Owazamono.
The blade does not matter. The weilder does.
From your reasoning Ryuma would need to have been chosen by a Saijo. Which we know did not happen.
You can make a case for the Sandai to choose Zoro and make its way too him, but not for any other blade we know of right now.
There are only a handful of Saijo to go around and its not like their weilders will give them up freely.
Zoro only got Enma because it was in the possession of someone who is not a swordsmen and Zoro saved her butt.
Zoro only got Shusui because Ryuma did not need it anymore in the grave and want to pass it on.
Where would Zoro get a Saijo from if not from a defeated foe, like Gandhi, or so?
It seems that Ryuma was in fact not the Absolute King.. Shusui is only a Great Grade Blade..
Maybe Ryuma was the absolute King in Wano which was isolated from the world, but not the whole world of One Piece..
Just as Ushimaru was the '' Grandmaster '' Swordsman of Wano, but outside he's only a '' Master '' Swordsman..
Actually more than half of the Saijo don't have a Wielder or have not been introduced yet..
Even though Enma and Shusui are Great Grade Blades, they are a good indication that some Supreme Grade Blades
have no current Wielder and there are not enough Top Tier Conqueror Blade Wielders to go around currently.. There are
Saijos waiting to Choose a Conqueror with potential of being Top Conqueror..
I still don't like why nidai kitetsu was not picked up by Zoro. Felt like an obvious mis opportunity
You're right, and there must be a reason.. But one important thing, it's not that Nidai Kitetsu didn't get picked up by Zoro, it's Zoro that didn't get picked up by Nidai.. The Sword chooses it's Wielder.. Maybe each Kitetsu generation hate one another, or something else..
No weapon will surpass Yoru, the only supreme blade turned black.
If Yoru was already a Supreme Grade Blade, then it didn't become more powerful which would turn Yoru forged into a Black Blade the most useless thing.. We know Enma will become more powerful when it's going to be turned into a Black Blade..
Yoru was a Great Grade Blade.. No Supreme Grade Blade has ever been forged into a Black Blade ever before..
