Is that why Luffy asked his crew to go back and party and not worry about Ryokugyu? Oh wait that didn’t happen, Luffy was prepared to jump Ryokugyu with help from his crew lol, doesn’t seem like Luffy was confident that he could face Ryokugyu 1v1.
For comparison, Luffy asked Yamato to let him fight Kaido 1v1 lol.
