Two years earlier, he had shorter hair, wearing a red hair clips, blue jeans, and red/pink sandals.

As a little girl at the age of 2 years old, when it was found, She wore a dress without sleeves yellow with blue stripes, and brown sandals. After the adoption, wearing a pink dress without sleeves, which in the special and was changed to blue.

Personality
Nojiko is Nami's levelheaded older sister. She is highly supportive of Nami, her adoptive sister, and generous to Genzo, who she and Nami had seen as a father figure. Unlike her sister, she seemed to keep herself out of trouble, although she apparently had a habit of upsetting boys. As she grew older, she also became partly responsible for the well being of others on the island. During the years of Arlong's rule, she would try to prevent others from raising up against Arlong while Nami worked hard towards honoring her deal with him.

She doesn't like people who would throw away their life recklessly. She also has a belief that if you no longer have the will to live and wish to die, so long as you try hard enough, whether adult or child, it will not matter.

Past
When he was only 2 years old, he found himself in the middle of a battle between pirates and marins. I leave death and destruction around her, many people, including his parents, were killed, at the end of the clashes began to wander, and met Nami, who was still an baby girl, she remained orphaned, continuing in searches met Bell-mère. Using what little strength she had, Bell-mère pulled herself over to the the two little girls and to the relief of both Nojiko and Bell-mère, the baby girl (Nami) laughed seeming unaware of the bloodshed that happened.

Soon afterwards, Bell-mère set sail for her home town with the two little girls and arrived back home during a storm. She handed over the two little girls to the village doctor even though she was hurt. Much to the villagers' surprise, Bell-mère announced after all three were better that she was adopting the two little girls, Nojiko and the baby girl (who had been dubbed "Nami" by then), something Nojiko was apparently happy about.

Their life together was a struggle as Bell-mère was poor. Being the elder of the two adoptive sisters, Nojiko had everything bought for her first and Nami would end up with her hand-me-downs. After scolding Nami for denouncing them as a family causing Nami to run off, Nojiko was sent after her.

That same day, when he was 10 years old, Arlong invaded the island and found her home, Bell-mère tried to fend the fishman off but was quickly subdued. When asked for the fee needed to stay alive, it turned out all the money Bell-mère had would either save herself or her two adoptive daughters. Things would've been okay, as Arlong was unaware of the two little girls' existence, but Bell-mère gave it to her two little girls as she would rather have died than not call herself a mother. To that end, Arlong shot her right in front of the eyes of her two adoptive daughters, but not before Bell-mère apologized to Nami for not being richer, and not being able to buy the little girls whatever they wanted. With that, she said her final words to the little girls: "I love you."

Arlong Park Arc
In the present storyline, she saves Usopp and a boy called Chabo from the hands of the fishmen.

She reveals Nami's past to the Straw Hats in return for them to leave the island. After trying to stop Nami from attacking captain Nezumi, a Marine officer who tries to take the money Nami raised for her deal with Arlong, Nojiko was shot by him in the back. However, she survived. She also aided in the rescue of Luffy with the help of Genzo after Luffy is thrown into the ocean by Arlong with his feet stuck in a chunk of concrete.

Post-Enies Lobby Arc
She is later seen after Nami gets her first bounty, apparently content with the idea that she is at least smiling in the photo. She gets confused with the ironic fact that Genzo becomes outraged by the picture on Nami's bounty poster, in which she is only wearing a bikini, even though he possesses an enlarged copy of said picture.

Two Years Later
After the Straw Hats reunite, Nojiko is seen by Bell-mère's grave with Genzo, Chabo, and Nako. She and Chabo are both wearing aprons displaying Nami's tattoo and tangerines, suggesting they made it into a business.

Relationships
Nojiko always had a fairly content relationship with Bell-mère and never saw a problem with being adopted. Unlike Nami, she was aware of the situation she was found in by her and she laughed alongside Bell-mère about how Nami had been unaware of the bloodshed that happened around them.

Growing up, she often supported Nami's bad habits of stealing, much to Bell-mère's annoyance. She was deeply angry at Nami's original recruitment into Arlong's crew, but at the same time knew her sister enough to realize that she would not join the crew without reason. Nami's forever hatred of her tattoo led Nojiko to get her own and at the time she told her adoptive sister she got her tattoos because she wanted some body art like Nami's, something Nami never forgot about when it came round to finally remove Arlong's tattoo.

And an orphan, and probably Nojiko had another family, as has been found in a destroyed village, and clearly that is an orphan of war, since he was only 2 years old, was too little to remember the faces of his parents, not clear whether he had any brothers or sisters.

Trivia

 * In a response to a fan about whether Kuina and Tashigi's names come from birds, Oda also mentioned that Nojiko's name too comes from a bird, a Japanese yellow bunting.
