No dude, the exchange of blows happened before they split the skies.
- Roger and Whitebeard = It was during their first strike.
- Kaido and Big Mom = It occurred during their first strike.
- Shanks and Whitebeard = It took place during their first strike.
- Luffy vs Kaido after becoming one-on-one = Their first strike.
- Luffy vs Kizaru = Luffy's first attack is him kicking Kizaru's arm, and Kizaru defends himself like a woman. lol
But that's ok, let's wait and see what kizaru shows.
