One Pace

As they depart the Baratie in pursuit of Nami and the Going Merry, Yosaku warns Luffy and Sanji about the vicious Arlong and his Fishman underlings. Meanwhile, Usopp, Johnny, and Zoro make landfall where Nami docked the Merry.

Usopp, having challenged the Fishmen, has been caught. To effectively prove her loyalty to the Arlong Pirates, Nami is left with a morbid choice.

Luffy's group has reached the island but are met with a shocking revelation. Unmoved by Nami's apparent actions and her insistence that he leaves, Luffy stubbornly sticks around.

Nojiko goes into detail about Nami's childhood and their adoptive mother Bell-mère, a former Marine. Despite being poor and unrelated by blood, they had a happy life on their tangerine orchard.

When a Marine officer under Arlong's pay confiscates all the money Nami accumulated over the years, it becomes clear where Arlong stands on his promise.

Nami's audible sorrows have reached the ears of a certain Straw Hat captain, and he and his crew rise to action. The villagers look on in awe as the Straw Hats boldly enter Arlong Park to face the Fishmen.

Luffy's newest move leaves him incapacitated and at the mercy of the sea while Zoro, Sanji, and Usopp desperately fight off Arlong's top officers.

The top officers are defeated, but Sanji and Zoro are no match for Arlong. However, with Luffy finally free, he just may just be able to pull it off. Meanwhile, Nami finally gathers the courage to face Arlong.

Luffy springs into action against Arlong, and their intense struggle commences. Luffy becomes enraged when he discovers how exactly Arlong had been using Nami, and he comes to a quick decision on how to finally free her of her shackles.

Arlong's reign of terror is over, so the island throws a party to celebrate their freedom and to honor their pirate saviors. During the festivities, Nami makes her decision to officially join the Straw Hat Pirates.
