A/N: This one is to the theme of 'brothers and sisters' on akikorossella's deviantart. Miles and Nene are Natsu and Lucy's kids. Enjoy :)

Siblings

"Nene!"

"It isn't my fault!"

"Oh? Then whose is it? Gilbert's?"

"Pff. Very funny, Miles. Gilbert is a cat, and he's at home!"

The ten-year-old boy, Miles, smacked his forehead. "I wasn't being serious, you idiot!"

"Don't call me an idiot!" seven-year-old, Nene, stomped her foot, stopping in the middle of the road and flipping pink hair out of her eyes.

"Just shut up and keep up or I'll leave you behind!" Miles kept walking. He knew she would follow. They had to hurry and she would be too scared to stay alone. He hated taking her to the park. She got distracted over everything, walked as slow as a snail – those were the reasons they were in this situation – and she was a moron sometimes.

"Miles!" Nene whined, running to catch up to him. She latched onto his arm, tugging to pull him to a stop.

He growled slightly, yanking his arm free and making her stumble. He looked down at her, ready with another scornful remark, but halted at the look on her face. "What now?"

"The man," she whispered, staring up at Miles with fear-filled brown eyes. "The man in the long coat who has been following us. He's still there."

Miles chewed his cheek and then forced an unconcerned look. "I told you, already. It's okay. Everyone in Fiore knows who our parents are. They wouldn't dare touch us. So just keep walking and stop worrying about him."

The little girl wasn't convinced though. She grabbed her brother's coat with trembling fingers. "Look, I'm sorry for getting in a fight with Rina. I won't do it again."

Her fight with little Rina was what had delayed them. They should have left the park an hour ago but Rina and Nene started fighting over whose dad was better. As per usual.

Miles sighed, reaching down to take his sister's hand and tug her along with him. "It's fine. Let's just focus on getting home for now," he squeezed her hand. "What are you even worried about? If that man has an issue with us, I'll take him out myself."

Nene nodded, smiling a little. "Oh yeah! I can help! Happy gave me mama's old whip," she giggled.

"Nene," Miles groaned, glaring at her. "She'll kill us both."

"I just borrowed it," Nene said. "Besides, I'll blame Happy."

"Happy's too good at getting out of –" Miles cut himself off. The man had gotten closer. He gripped his sister's hand tighter and pulled her, forcing her to keep up to his pace.

"Miles," she whined, squeezing his hand.

He made an abrupt, and probably stupid, decision. He turned to face the man, simultaneously pushing his sister behind him, and pulled out Cancer's key. "All right, old man, what do you want?"

"Oho," the man laughed, stopping as well, and placing a hand on his dark hat. "You're a Celestial Spirit just like your mama, brat?"

Miles pushed some of his blond hair out of his eyes and held up his key. "Answer me,"

"I'm a man who was defeated by your runt of a father, many years ago. I've finally gotten out of prison and I've come for revenge, of course," the man tipped his hat back, revealing dark eyes and light coloured hair.

Miles laughed. "On his kids? That's hardly fair. You got a problem, you take it up with my old man, not my sister and me."

"Miles," Nene said again, nervously.

He licked his dry lips, squeezed her hand, and whispered, "Go home, I'll take care of this."

"But…"

"Just go," he snapped. He didn't care what happened to him, he wasn't going to let his little sister get hurt. His parents would kill him.

"Miles," she whispered. "I'll bring papa back!" And off she went, hurrying as fast as could with her little legs.

The man snorted. "Now that that precious moment is over, let's get to business kid. I don't care if the brat gets your father. In fact, that's what I want. But before he gets here, you'll be dead, so your papa," he mocked, "can witness the death of his little boy."

"Pff," Miles chuckled. "That's pathetic. Open the Gate of the Giant Crab! Cancer!" With a flash of light, the Celestial Spirit Cancer stood between Miles and the man. "Cancer could give you a nice trim, if you'd like."

"Miles, you too could use a snip," Cancer said and Miles waved it away.

The man laughed again. "Bring it, boy. Without your father's fire magic, I bet you're useless."

"Hardly," Miles said calmly. "Cancer."

The Spirit lunged forward, his scissors snipping wildly. The man dodged left, then right. He pulled out a small, circular object and held it out, as Cancer got close. The crab spirit disappeared with a flash of light.

"What did you do?" Miles demanded, jerking in surprise. "What did you do with Cancer?" His mom would so kill him if something bad happened to the Spirit.

The man laughed again. Miles found him even more annoying. "Tell me!" he snapped.

"This," he held up the object, "is a magic mirror. I bought it from a very shady guy back in –"

"Old man, I don't care. Just tell me what it did to my Spirit," Miles growled.

The man looked offended. "Brat. Just like your father. Ooh, I hate that pink-haired dragon slayer!"

Miles clenched his teeth. "Seriously," he mumbled. "You're getting on my nerves."

"Oh, very well! Your spirit just got trapped in the mirror, that's all! My, you're touchy. If you break this mirror, your little crab will come back just fine. As will all the other pathetic people trapped in here. You're next, blondie."

The man began to walk towards him, and Miles stood still, perfectly calm. This made the man pause, his eyebrows lifted. "Scared?"

Miles snorted. "In your dreams, old man." He reached into his jacket pocket, pulling out the other key his mother had given him. "Open the Gate of the Scorpion! Scorpio!"

"Shit!" the man hissed, holding his arm up to block Scorpio's flash of light. "You had more keys?"

"Scorpio," Miles said, "be careful of that strange circle thing. It can trap you in it if he points it at you. Aim for it. Break it. Cancer's stuck in there."

"Got it," Scorpio grinned. "Sand Spear!"

"Ahhhhhh!" the man screamed, covering his face with the hand holding the mirror. Scorpio's attack hit the mirror, causing it to shatter, and send the man flying.

Cancer appeared, along with a variety of different mages, all wearing expressions of bewilderment. Miles sent Cancer and Scorpion back, the stress of having too many gates open taking hold. He collapsed to his knees, cursing. He wished he were as strong as his mom.

The man groaned, sitting up only to be faced with many angry mages. "Now now," he tried.

Miles grinned slightly and then heard his name. "Miles! Miles!" it was Nene and she was shaking his arm. He looked at her, where she was suddenly kneeled beside him. He looked up, meeting his father's grin.

"Hey kiddo, good job," Natsu Dragneel snickered as he leaned down and thrust Miles over his shoulder. "Who's that guy, anyway?"

"I told you, papa, he said you kicked his ass a long time ago," Nene said, taking her father's free hand.

"Dad! I can walk!" Miles protested but Natsu ignored him.

"Eh, I don't remember him. Hah, my kid sure showed him though! Wait till I tell Lucy!" Natsu patted Miles back repeatedly as he spoke, causing the boy to wince. He sighed though and let his father carry him home. He was too tired anyway.

"Good job sending your sister home too, Miles," Natsu said once he'd calmed. "Family comes first, always!" the dragon slayer snickered again.

Miles sighed again, relaxing on his dad's shoulder and closing his eyes. "I know, old man," he muttered and felt himself drifting to the sound of his sister's chatter and father's laughter.
