You mean Kuina and Zoro aren't connected through Wado ichimonji?
What about Roger, Shanks and Luffy being connected via the strawhat that just happens to show up in Marie jois?
What about Zoro and Ryuma being connected via Shusui to the point that Shusui itself chose Zoro as it's master?
Okay then what about what Kawamatsu was saying in chapter 934 about ALL THE WANO SAMURAI who died in the past being connected to the rebels fighting for Wano now by their swords being passed on?
Surely Zoro getting offered Oden's sword in the Chapter 934 when the entire chapter is centered around people inheriting will via swords would mean Zoro has some connection to Oden?
If your answer to everything above is YES until the last question where you say NO to a Zoro and Oden connection then you my friend just discovered what "Bias" means
Zoro has nothing in common with Oden, other than the Swords.
Everything else, Oden is Luffy.
Oden is 100% Samurai Luffy.
Oden is exactly like Luffy with a different fighting style.
1)Oden is obsessed with freedom like Luffy. He always wanted to be a pirate since he was a child like Luffy.
2)Oden has Conquerors Haki like Luffy
3)Oden has Voice of All Things like Luffy
4) Oden has Charisma to attract allies like Luffy and charm people
5)Oden was age 19 when he took over Udon and defeated Shutenmaru like, Luffy is age 19 right now taking out the Yonko.
6)Oden became Damaiyo at age 20, like Luffy will become Pirate King at age 20.
7) Oden has 9 Scabbards like Luffy has 9 Strawhats.
8) He causes chaos wherever he goes like Luffy.
9) Zero Navigational skills, kir Luffy
10) His trademark catchphrase" It's too Cramped"was said by Luffy in Dressrossa.
11) He likes Adventure like Luffy
There has not been 1 place Luffy has visited without being in chaos, just like Oden.
Kozuki clan is 100% a secret D like Trafalgar Law's family.
Oden is 100% Samurai Luffy
Roger was also a Swordsman, so the Swordsman Zoro parallel does not work.
