sanji isnt the one that cant stand up after fighting an infant seraphim in a 2v1 with zoro
tbf
he doesnt need to prove he can beat kaku
kaku needs to prove he isnt a jobber.
Sanji could barely stand up fighting Black Maria's fodders.
What an actual fuck are you on about
We literally don't know what happened
Plus S Hawk Stomps Sanji too
Acting like same Infants wasn't tanking a Yonko's named signature attack and had him sweating like a bitch
Kaku stomps Sanji and is probably stronger than Lucci
