Chapter 422: Rob Lucci
Marine: Vice Admiral! What should we do about the capture of Nico Robin at the Bridge of Hesitation?
Vice Admiral: Just leave her.
Marine: !? But…
VA: It was 15 years ago...
VA: In a kingdom, 500 of the soldiers were captured by pirates.
VA: The pirate leader was using the hostages to try and take the throne.
VA: Because of the hostages, the kingdom was unable to do anything.
VA: They were on the verge of surrender when the World Government sent a single boy...
VA: The boy entered the pirates' base...
VA: And right in that place...
VA: He killed the 500 soldiers being held hostage!!
VA: The boy turned to leave the mountain of corpses.
VA: The pirates were angry, and they fired on the boy.
VA: But he stood up amongst the explosions,
VA: Took the head of the leader, and solved the situation.
VA: With many scars on his back from the attacks, the boy was only 13 years old.
VA: He became part of CP9, part of the "Justice of the Dark".
VA: He is stronger than any other CP9 member ever,
VA: And is called a ruthless "weapon of murder".
Marine: And he's...
VA: That man is on this island.
VA: He's taken on the mission of capturing Nico Robin.
VA: There's no need for us to interfere
VA: Until everything other than the Bridge of Hesitation is burnt down.
Marine: It's no good! The Sea Train won't move!
Marine: There's no engineer?!
Marine: No, we're gonna die!!
Marine: It's already reaching this far, hurry!!
Sanji: If water was coming down this tunnel...
Sanji: Wouldn't we die?
Soge: Zoro-kun, don't you hear it, it sounds like water!!
Zoro: Yeah, you're right... It seems weird...
Zoro: The old woman and Nami are getting chased by water!!
Soge: See!! this tunnel's getting filled with water!!
Chimney: Ah! It's the pirates!
Nami: You guys, do something about this water!
Sanji: Nami-san is...
Sanji: coming over to me!
Soge: Are you sure?!
Zoro: This is bad! We're gonna get closed in!
Zoro: ? I can't cut it, it isn't stone or steel?!
Sanji: It's an underwater tunnel. It's probably made out of some really strong metal to stand up to the water pressure.
Soge: So, there's nowhere to run!!
Lucci: I'm losing conciousness… I can't fall in the ocean...
Marine: Who is it?
Marine: A monster?!
Marine: No, it's a devil fruit user!
Lucci: _A battleship's…_u
Marine: He flew from over by the bridge!
Lucci: helm? I'm safe…
Marine: I also saw a huge hand!
Marine: He really does have a devil fruit!
Marine: We're asking who you are, answer!!
Marine: Stop it, idiots! Lower your guns!
Marine: That person is…
Marine: Rob Lucci of CP9!
Marine: I apologize!!
Marine: I'm sorry, please spare me!!
Lucci: Don't open your mouths, you're hurting my ears.
Luffy: Gomu gomu no Rocket!!
Marine: What is it this time?!
Marine: Something came out!
Marine: That's the 100 million pirate, Mugiwara no Luffy!
Marine: Although he's fatter than I thought...
Luffy: Won't work! "Hone Fuusen" is really tough! ((hone fuusen = bone balloon))
Luffy: Gomu gomu no...
Luffy: Gigant Axe!!!
Marine: What? A giant?!
Luffy: Gomu gomu no...
Luffy: Gigant Whip!!
Marine: Wah, this is bad!!
Marine: The mast got cut!!
Marine: It's falling down!!
Marine: Their fight is dangerous!
Lucci: Shigan "Bachi"!
Lucci: Your power increases, but your speed drops.
Lucci: Rankyaku "Gaichou"!
Marine: The steel panels got cut!
Marine: This ship is dangerous!
Luffy: This's bad, I almost got cut in half!
Vice Admiral: What is it?
Marine: Yes, Vice Admiral! Mugiwara no Luffy and Rob Lucci of CP9 are fighting.
Marine: The ship is being destroyed...!
VA: Since it's Rob Lucci, we can't let him die.
VA: All ships aim at ship number 4.
VA: In five seconds launch one attack.
Marine: Wha... Vice Admiral, please stop joking! 1000 of our own men are on that ship!
VA: With a single moment of unsurity, allowing such a dangerous thing to occur...
VA: Can you protect the future?
