Still cant find Luffy saying "dont kill Vegapunk or my nakama
by which i mean Sanji etc, not Zoro", you sure you're not lying about this? Nothing state Luffy excluding Zoro from the term "his nakama" or including Kaku to be "the one being able to kill his nakama".
Also why should it be the conclusion that Lucci "couldnt even" attack Zoro when Lucci saw himself that Kaku wasnt even damaged by Zoro's two-sword attack? Seems like you just dish out and made your own version of Lucci's reasoning outta nowhere.
Btw i wanna read that Sanji's comment myself, in which chapter was it? You're being sus right now.
