When Nami's mother announced she was getting married, Nami pitched a fit that would have shamed a hurricane. It wasn't that she didn't want her mother to get remarried (although experience with her mother's past boyfriends had taught her that might not be such a good thing either), but it was the news that the man she was planning to marry had a son. Soon Nami would have another sibling and she was anything but happy about that.
Things were bad enough with just her and Nojiko. She loved her sister to death, but, like teenage girls will do, they fought like mortal enemies sometimes. Not to mention due to their less than awesome financial situation, Nami was usually forced to cope with her older sister's hand-me-downs, be them clothing, gadgets, and even the car. Having yet another sibling - a boy of all things - could hardly help that situation.
That was why Nami had thrown the fit of the century before locking herself in her room and refusing to come down to even meet the new additions to her family.
The knock at her door an hour later roused her from her bitter thoughts. She had half a mind to tell whoever it was to go away, but figured she'd been hiding long enough she could at least face whoever it was. Maybe her mother had decided to cancel her engagement. Nami snorted at herself. That was ridiculous and she didn't truly want that anyway.
On the other side of the door a rough looking boy about her age stood. When she opened the door, he beamed at her with the widest smile she'd ever seen.
"Hi! I'm Luffy, we're gonna be siblings from now on!" He announced, and then, without waiting for her response, pushed the door open further and invited himself into her room.
"Hey!" She protested, following behind him. He ignored her, looking around her room with some interest before marching over to her desk and peering down at her collection of maps.
Some of the maps came from books and atlases and many were maps she'd drawn herself. Maps of her hometown, or her backyard, nowhere fantastic or special but one day she'd be able to map out the world once she saw each and every corner of it firsthand. That was her dream.
Luffy picked up a particularly old map from the stack. It was something Nami had found hidden away in an old book store and spent all of the allowance she had saved on. It was outdated and inaccurate compared to the modern maps they had now, but that was what she found most fascinating about it.
"Don't touch that!" She cried, smacking his hand away from it.
"Why not?" Luffy asked curiously. Then a kind of understanding seemed to dawn on him. "Ohh, is that your treasure?"
Nami stared at the boy, surprised by this bit of insight. "Yeah, it is," she said.
Luffy laughed, a genuine laugh that was almost contagious. "Oh! I see!" He stepped away from the maps beaming at Nami for a moment before his smile fell. "Your mom said you didn't want to have a new family," he stated.
A scowl returned to Nami's face. "That's right, I don't," she said, her words slightly biting.
"Why not?" Luffy asked. His head tipped slightly to the side in confusion. "Won't it be fun to have more people around to spend time with? My dad's a really cool guy, and we can help protect your treasures too."
He pointed to the maps. Nami looked at them too. It wasn't as if they were something special and sacred that anyone would come after. In fact she was willing to bet if her house were to get robbed right now, the burglar would pass right by them without sparing them a glance. But the sentiment behind his words was… nice. It meant he understood the value her maps had, even if it was just to her.
"You see this?" Luffy pulled a straw hat from his back. Nami had noticed it hanging from his neck, but hadn't thought to comment on it yet. It seemed like an odd accessory for a teenage boy to have.
"This is my treasure. A very important person gave it to me, and some day, I have to give it back," he explained.
He took the hat from his neck and placed it onto Nami's head. She gaped at him, a little surprised. If this hat was so precious to him, why would he put it on her?
"We're a family now, so you're gonna keep my treasure safe too!" He said with an excited smile.
Nami gingerly touched the brim of the old straw hat. Maybe having a brother like Luffy wouldn't be so bad after all.
