What the use of using it if you still get wrecked?
If Oden who was low top or YC1 had it and was wrecked
What will Zoro Shuten accomplish with it?
Also Kawamastu was the only one who took care of Hiyori
And It seems like he doesn't want anyone to wield Oden sword.
So why has no one used it for 20 years if its a magic kaido sword ?
Oden + Emma = dead and his rule easily crushed.
Zoro + Emma = you expect him to somehow do better vs Kaido
