Oda, Eiichiro

The Straw Hats, while working on repairs to the "Merry Go," face the Foxy Pirates in three challenges, and Admiral Aokiji, who knows about Nico Robin's past, finds them.

The Straw Hats, having learned the reason behind Robin's betrayal, try to rescue Robin, Usopp, and Franky from the CP9 assassins and worry their new ship, the "Rocketman," will not be able to handle the voyage through the tidal wave known as Aqua Laguna.

Luffy continues to battle CP9 agent Rob Lucci while his crew escapes through the Gates of Justice, but when a fleet of Navy Headquarters warships shows up and starts bombarding the island, the entire crew is in jeopardy.

In order to save Robin, Luffy must get past the deadly assassin Rob Lucci. The rest of the Straw Hats are engaged in their own battles to find the special key that will release Robin from the tower.

The Straw Hats need a special key to release Robin from the Tower of Justice where she is held captive. One of the CP9 assassins holds the right key but Luffy and his crew may have to defeat them all to save her.

The Straw Hats and Franky's crew must join forces if they want to rescue Robin and Franky who have been captured by CP9 and locked up on Enies Lobby, but first they must face Spandam's six deadly assassins.

Sanji, Usopp, and Franky face off against the Navy while the rest of the Straw Hats hurry to catch up to the Sea Train and free Robin from the clutches of CP9.

The Straw Hats, having been left by Robin, uncover the real motive behind the actions of the CP9 assassins and try to stop them from using the most destructive weapon of the ancient world.

Nico Robin is blamed for the attempted assassination of the mayor of Water 7, and the Straw Hats try to clear her name while uncovering information that the members of CP9 might be the real culprits.

Luffy, working with Usopp to repair the "Merry-Go," faces a tough decision when his money is stolen and he has to determine what will happen to the ship.
