So kaido uses a technique called 3 worlds and zoro uses 3 thousand worlds and kaido uses raimei hakke and zoro uses hell hakke.
Coincidence? I don't think so
Hell Hakkei isnt from Zoro but Kaido:
Read it like this first dialogue:
Zoro: <<you should take my head... before you get ahdead of yourself>>
Zoro:
<<demonic Nine sword style>>
Kaido: (look his eyes pretty shocked)
Zoro:
Asura!!!
Kaido: <<Ugh,
Hell Hakkei!!!!>>
Zoro:
<<Farce of the dead>>
Kaido:<<Arrgh!!>> (Zoom on Kaido face - he is suffering heavly pain)
Kaido:<<Gro Aah>> blood coming out
Law: Mounth fish (totally shocked)
So the move that Zoro use is called: Demonic Nine Sword Style Farce of the Dead
At the same time Kaido counter attack with Hell Hakkei
This panel is just insane!!
