What effect does Kairoseki's have on Haki? When a Devil Fruit user is locked with Kairoseki, is there any affect on his Haki abilities.
Like in episode 627, couldn't luffy use Conqueror's Haki when he was in the cage made of Kairoseki?
Kairoseki has no effect on haki. Rayleigh could use Haki while being chained in the auction house ( during the sabaody archipelago arc).Also haki is inborn quality in every living thing in one piece world as said by Rayleigh. And kairoseki only affects devil fruit users. Non devil fruit users are not affected by kairoseki. So they can use haki however they like still being chained.
