A.N: I started to write this ages ago, but I didn´t have time to finish this because of my other fics. And now I´ll continue writing them since I got this done. I got an idea for this when I saw a LuNa music video where Nami watched Luffy with teary eyes when she was sent away by Kuma. And I also wanted to write a story about Nojiko since there isn´t much of them. Well, enjoy!

The broken promise

Luffy watched how his nakama, one by one, were sent off by Kuma of the shichibukai. But when Nami, his navigator and a very good friend, was sent away, his mind started to go crazy. Nami´s teary, terrified look when Kuma made her disappear just didn´t go away from his mind. Nami´s yell for help rang in his ears.

"NO!" he thought "This can´t be! I broke my promise to Nojiko!"

Luffy was trying to fight back tears; tears of sadness, tears of anger and regret. He had betrayed her. He had made promise to Nojiko, but he hadn´t been able to keep it.

Flashback:

Luffy was walking, eating and laughing at the same time in the village of Cocoyashi, Nami´s home. He was really happy, because now Nami would join them without any problems.

Out of the corner of his eye, he saw Nami´s sister, Nojiko, walking out of the village.

"I wonder where she´s going", Luffy thought and started to follow Nojiko as silently as he could.

Nojiko took an orange from a bush and started to eat it. Oranges had always been something that calmed her down.

"Arlong´s down, but Nami still isn´t going to stay home!" she thought as the tears started to run down her cheeks.

"What makes you so sad?" this made Nojiko jump, she hadn´t heard anyone coming. She turned her head and saw her little sister´s boyfrie- err, captain.

"Don´t scare me like that!" Nojiko snapped. Luffy put his hands in front of him, defending himself.

"Sorry", he said and looked at the woman´s teary face.

"Why were you crying?" he asked. Nojiko blushed and turned her head away and yelled: "I´m not crying!"

"You´re lying", Luffy said simply and finished the meat he was eating.

"You can tell me, I won´t tell anyone." he added.

"There´s nothing to tell", Nojiko said calmly. Luffy watched Nojiko for a moment. Then he walked over to her and took an orange from the bush.

"It´s about Nami, isn´t it?" he asked while he peeled the orange. Nojiko rolled her eyes. What else could it be about anyway?

"So what?" she asked.

"Are you worried about her? Don´t you want her to leave?" Luffy asked and put the first piece of orange in to his mouth.

"Of course I´m worried about her! She´s my sister!" Nojiko yelled, annoyed.

"Do you think it was easy for me to sit here when my sister was risking her life with pirates! I was sick because of worrying!" she continued her yelling. She collapsed on to a chair close behind her and continued: "How could you even know what I´ve been through! You have no ide-"

"I have a brother", when Luffy said this, it silenced Nojiko. He took another piece of orange and continued: "He´s a pirate, just like me. He´s three years older than me and left our home three years before me."

He turned to look at Nojiko.

"Do you think I´m not worried!" he asked. Nojiko looked at her feet.

"Did your brother chose to be a pirate?" she asked finally. Luffy nodded.

"Yes, he did." he said. Nojiko glared at Luffy.

"Like I said, you have no idea what I´m talking about. Nami didn´t choose to be a pirate, she was forced to be one!" she yelled. Tears started to fall from her eyes again when she watched Luffy who didn´t even flinch.

"That might be true", Luffy said and finished the orange "But there is always another choice."

"What do you know about-"

"I used to have two brothers", Luffy said before Nojiko could finish "The other one´s name was Sabo. Me and him weren´t biological brothers, and neither were Ace and I."

"….but you were still brothers", Nojiko said. She knew what Luffy mean, she and Nami weren´t biological siblings either.

"Yeah", Luffy said and started to peel another orange "Sabo was born in to a rich family, but he wasn´t happy. So he took off and became a pirate, but…" Luffy couldn´t finish his sentence. Now it was his turn to cry.

"But he died", Nojiko finished for him. Luffy nodded and Nojiko sighed.

"If pirating was what killed him, then why did you and your another brother became pirates?" she asked. She didn´t get him at all.

"It wasn´t pirating that killed him, it was this world." Luffy told. Now Nojiko didn´t understand at all.

"I don´t get what you are trying to say", she said.

"He was shot, or that´s what I´ve heard. Shot by a world noble, by someone who the government protects." Luffy told.

"Oh", Nojiko said, understanding a little better.

"But aren´t you and your brother afraid of getting killed, too?" she asked. Luffy sighed.

"Yes", he replied "But how could we face Sabo when we die, if we were cowards who wouldn´t try to make their dreams come true like he did?"

"…he was really important to you, wasn´t he?" Nojiko asked when nothing else didn´t come to her mind. Luffy nodded.

"Yeah, but that´s in the past. Now I have something else I need to and I´m going to protect." he told.

"Your crew?" Nojiko asked and Luffy nodded. Nojiko sighed, but a small smile still came to her lips.

"Then promise me something", she said, looking straight at Luffy with steady gaze. Luffy looked at her, waiting for her to continue.

"Promise me that you´ll keep my little sister safe", she said. Luffy grinned his usual grin.

"Of course!" he said, fixing his hat. Now Nojiko smiled too. She now knew that Luffy would keep Nami safe, because she was important to them both.

The end of the flashback

"I´m an idiot! A weak, stupid idiot!" Luffy thought. Nami had disappeared, he had broken his promise to Nojiko. He looked at Chopper and Robin, the only remaining members of his crew.

"I´ll think about Nami later, I need to protect Robin and Chopper!" he thought "But I´ll definitely will get Nami back."

Nojiko dropped her mug of hot coffee, causing Genzo to look at her.

"Is something wrong, Nojiko?" he asked. Nojiko blinked and shook her head.

"No… I just had this weird feeling." Nojiko told. Genzo sighed, it wasn´t the first time Nojiko said something like that.

"Don´t worry, Nami´s safe. That Straw hat kid is taking care of her." he told. Nojiko nodded, but she still couldn´t stop worrying about Nami.

"Please, Nami, be safe."

A.N: There! Short but I think it´s okay. Thanks for reading! Review?
