Yes after boosting his speed
Basically did a base katakuri tier feat
Impressive...the difference is that katakuri actually damaged g4 luffy while Kizaru couldn't
How do you boost LS? He was just preparing for a larger attack and owned Luffy's 2nd strongest mode with no real issues.
If Luffy wasn't a Yonko and defeated Kaido, I'd still believe he had a long way to go until he can defeat a top tier.
Plus, Ray didn't show everything as well but he'd eventually lose due to lack of stamina and skill (he hadn't touched a sword for around 2 decades after all). It still would be much closer than Snake Man vs Kizaru though.
