The four of you aren't fooled by his disguise and can tell that he's Usopp.
"What the heck is he doing?" Franky asked in disbelief.
"Well, try to understand his feelings. He feels he can't go rescue her outright as a friend. So this is his way of settling things" Sanji explained.
"In short, he just has too much pride to show his face to the rest of the crew but he still wants to save Robin" you clarified.
"Let's just humor him for now" Ghin suggested.
"Geez . . .what a pain" Franky commented. "Hey!! Come over here!!"
"Oh, okay" Usopp replied and came to our side.
After settling down, you all were seated around to devise a plan.
"Okay then. We'll have the meeting for Operation Rescue Robin now" Sanji announced. "First of all, the car you guys were in was #6 so there are five more cars left" He turned to Franky. "By the way, are you strong?"
"I'm super strong, you idiot!! I'm especially strong this week!!"
"At least you can fight but right now, we are outnumbered as there are a lot of enemies so we need to avoid unnecessary fights as much as we can and save our strength for the main forces," you said.
"Hm. It makes sense. You've got a good point, Arsene"
"So here's the plan . . .listen closely"

Sanji, Ghin, Franky, and Usopp prepared to put your plan in motion. While they are distracting the small fries, you make your way to the other side of the car to prepare to detach them once all of them are gathered. Once everyone was in, the four of them quickly climbed up and ran to the next car. The small fries realized this but it was too late and you detached the cars, leaving their shocked faces behind.
"Well, I haven't made a strategy in a while. This plan isn't even a good one so I must've gotten rusty" you commented as you threw the chain away. "Well, I'll leave the rest of the small fries to you, boys"
You opened the door to them, not realizing that one of the small fries is trying to kick down the door and fell into the ocean.
With CP9, one of the guys was reporting the status of the situation.
"And the other one is the woman with two swords on her waist and a spear on her back. So it's a total of 5!!"
"Hmm, just like the long-nosed man, those men are probably one of the Straw hats. Naturally, their purpose is to recover Nico Robin. Franky is helping them out. As for the woman, she must be Arsene, one of the Shichibukai, and is probably helping them out as well. That's probably about it" Kaku said as he analyzed the situation.
Back with you, you are internally pissed off with that guy's same expression and smugness. You wanted to cut him into pieces. You didn't even realize that you started heating up literally.
"Aaaah!! Arsene, you're burning!!" Usopp exclaimed.
"Hah?? What the fuck are you saying right now??" you glared with a very dark murderous aura.
Franky shivered. "What he's saying is that you're literally on fire!!"
"I don't give two shits right now" you unsheathed Takame and used full force to create two slashes. One vertical and the other horizontal. The annoying chef managed to dodge it but created two big cuts of the car and around it. The horizontal slash cut the car you're currently in, in half and the next two cars with it while the vertical one did the same thing and the current car is now badly damaged.
The annoying chef finally changed his expression and is now in complete shock at the damage you have done.
You took a breath in and out before you calmed down. "Now, can you let us pass??"
The chef nodded vigorously and let's you to the next car.
"I guess we don't have to worry about our next enemies in the other cars . . ." Franky commented while Usopp was internally scared shitless.

Now you are face to face with CP9.
"Arsene, why are you helping the Straw hats out?" Lucci asked.
". . .Why, you say? It's to help get Nico Robin back and I'll pull her back from the depths of hell if I have to" you replied. "What you said earlier. You think your taunts will work on me?"
