Kizaru isn’t gonna be clowned next chapter lol, he would have some difficulty at first as most opponents when Luffy pulls out the news PU, but gradually he gonna get the hang of it and somewhat overwhelm Luffy before Luffy does a new skill/technique as usual and surpasses his enemy.
Honestly it’s 101 Oda’s way of writing Luffy’s fights. However, the outcome of this particular fight could go either way(since it’s hard to tell what’s Oda’s attention) 1- Luffy wins or 2- fights end with both seemingly equal in power with no clear winner. Both conclusions imo is a W for Luffy as he is the newest top tier in the game.
