No, it's swordsmanship
Asura is (Nine sword style)
and it's Zoro's own will manifestation. Haki/Techniques are all okay here. I just want to see sword fight that has NO DF involved. It's been long time, last time it was Ryuuma. And Zoro vs Killer was so god damn fast
Does having other things that enhance your swordsmanship make it a less interesting fight though?
Lets say Kyoshiro has a Basilisk DF, his Zoan form would give him strength buffs even though he was relatively matching a nerfed Zoro in strength that one time and then Zoro would have to pull out that Gorilla mode of his that's not appeared since Ennies Lobby. Then Kyoshiro would have either wings or a tail or both (making him look like Ulquiorra from Bleach) which two he can use in the fight to like make a four sword style type thing like how Kaku used Rokushiki on top of his swordsmanship to make a four sword style. And this could force Zoro to use like Ashura to meet the variety of weird abilities Kyoshiro would have using wings and tails and shit to fight. Then lastly Kyoshiro would have paralysis abilities with his eyes to force Zoro to add on strategy to beat the guy and deal with his abilities.
This is a hundred times more interesting no?
People say Kyoshiro has the makings of Zoro's final fight of the arc but surely Zoro can't move from Cutting a mountain in the climax of an arc to a very mandane quick one shot and done fight. Like Samurai fights are just a bunch of choreography and then One shot. Thats how Kyohsiro would have to be if he literally had nothing else going on. This was fine with Zoro vs Ryuma because that wasn't Zoro's biggest moment that arc and that's why it's fine with Zoro vs Killer because that's also not a big moment. But surely this arc in swordsman land can't end like the same way as the Ryuma fight.
The only way I see this is being how the Kyo fight goes is if this is also not Zoro's moment and like Zoro will fight king or Kaido afterwards but then we already had Zoro vs Killer as a plain samurai fight so what would be special about Zoro vs Kyoshiro then.
