I wanted to, more than anything, stay with him forever.

Possession
Chapter 1: Meeting

"Did you get lost, little girl?" The elderly, dowdy woman chortled merrily, eyes crinkling from beneath her lens as if thinking of a private joke.

Said "little girl" frowned. She had been trying to convince the office secretary for 10 minutes that she honestly wasn't 11. It wasn't working. The old woman was hard of hearing. The girl frowned and could feel that her throat was sore. Shouting in the ear of the secretary had done no good. She cleared her throat and then took out the student card from her previous school out of her pocket. If this didn't convince the woman that she honestly, truly, really wasn't a stinking 11 year old, nothing would.

"No, obaa-san", she pushed the card patiently onto the counter. "I'm a new student registering here."

The mostly-deaf woman hadn't heard her, but she did see the card. She squinted at the information, at the picture, at her and then back to the photo. The old woman jabbed a knobbly finger at the 15 printed clearly next to the word 'AGE'.

"Are you sure this isn't a mistake?" The woman's eyes narrowed accusingly at the girl standing in front of her.

"...I'm quite sure", the girl said evenly. Her voice barely masked her frustration.

Tsuna was in a tiny dilemma.

You'd think he'd be used to it by now; being continually abused by Reborn, being stalked by Reborn, being pulled into astronomically big fights by Reborn, but he wasn't. No-good Tsuna could feel his grip slipping as he watched the havoc below him helplessly. He'd been shot by Reborn again with the Dying Will Bullet and had climbed up one of the sakura trees on the school grounds. Now he couldn't get down. The effects of the bullet had worn off and now he was stuck on one of the highest branches of the tree.

"HIII!" Tsuna squealed as Gokudera was knocked against the tree. The force of the impact was strong enough to shake the tree and Tsuna along with it.

Gokudera looked up at the shaking Tsuna.

"Juudaime! Are you all right?" His voice was filled with worry. Tsuna grimaced. He wanted to say, 'no he wasn't, he was piss-his-pants scared, so could Gokudera-kun please come up the freaking tree and save him?' He swallowed the words down. He knew Gokudera would be at a disadvantage if he wasn't focused on the fight.

"Hey..." Both boys turned to the direction of the voice.

Tsuna nearly fainted from the sight of the smirking Hibari Kyoya.

"If you don't put out the cigarette..." The disciplinary chairman held up his tonfas threateningly.

"...I'll bite you to death".

Gokudera scowled, cigarette in mouth, and whipped out his dynamite.

"Like hell I'm going to listen to you," Gokudera said contemptuously. Hibari's response was the slight narrowing of his eyes before he rushed towards the silver-haired boy. Gokudera dodged one of the tonfas only to be met with the other with a blow to his head. He was knocked back a few feet and his back slammed against the tree.

Tsuna shrieked again. Was it just him or was the tree beginning to tilt?

"B-bastard!" Gokudera spat out blood and rushed towards the waiting prefect. They exchanged a flurry of assaults. Being a mid-range attacker, Gokudera was at a disadvantage. He winced as Hibari's weapon landed a particularly hard blow to his stomach. Gokudera put a hand to his sore stomach.

Goddamn prefect.

"Fuck you!" he screamed angrily and hurled several sticks of dynamite at Hibari. He heard a bored sigh from the prefect, who then batted away the sticks of dynamite with his tonfas. Gokudera barely had time to duck as a few were tossed back at him. Phew, well, that was a relief. Gokudera got up from his fetal position, smiling triumphantly at the coolly watching Hibari. The bastard had thought he could injure him with his own bombs? Well, he thought wrong.

...

It took Gokudera a whole five seconds to realize what stood behind him.

The Sakura tree.

The Sakura tree his beloved Juudaime was in.

Fuck.

A loud "BOOM!" ran throughout the school.

"HIIIII!"

"JUUDAIME!"

"Finally."

It had taken an hour to convince the secretary, but she was finally out of the Namimori main office. She gave a cursory glance at the papers in her hand. It was her official student record that she had to give to a club known as the Disciplinary Committee. Her mouth parted contemplatively. The club must be pretty important if it was allowed to handle such confidential things like the folder she had in her hand.

She smirked. "Perfect".

BOOM!

The explosion knocked her off her feet. It was strong enough to make her skid back, like she was on a smooth sheet of ice, before she fell with little grace on her butt. She lost her grip on her profile.

"Oww..." She rubbed her poor backside, meanwhile trying her earnest to get up and see what all the commotion was about. What the heck could have made her fall down like that? Her eyes opened to see something astounding in one way and absolutely terrifying in another.

Eh? The girl stared in amazement at the burning sakura tree. The fire was slowly creeping up the trunk of the tree, making its way to the branches. Instinctively, her eyes followed its path. Her blood ran cold at the sight of something that made her bite her lip. There was a boy, tinier than her, dangling by his uniform collar from one of the higher limbs of the burning tree.

That branch looks close to breaking... Her assumption was right. She winced at the sound of the loud snap as the branch broke of the trunk, sending the boy hurling towards the ground. No doubt he would, at best, break a few bones in his body from that height.

Her eyes widened. The only conscious thought in her head while she was running towards him was that she had to save him. Watching something like that happen in front of her without trying to do anything would be the worst thing she could ever do. She could feel blood rushing to her ears, drowning out a loud "HIII", when she dived for the boy.

She only just managed to catch him.

The pair fell into a mess of tangled limbs. She firmly pushed the arm off her face as Tsuna groaned, her shoe smack dab on his nose.

She shot up, grimacing on his behalf when she heard his pained groan. He seemed to be half-awake as she crawled up to examine him. The loud groans were a sure give away that he was starting to wake up though.

"You okay?" Brown eyes alighted with worry as she looked at his wounds before softening with relief. At least his injuries didn't look serious. Most of his body had landed on top of her after all. But... The same couldn't be said for her.

Ow... She rubbed the small of her back to feel the newly-formed bruise. She winced. The sad thing was that the bruise wasn't the worst of her injuries.

"J-Juudaime!" Brown eyes opened to find a silver-haired boy pulling his barely-conscious friend up. She stood up cautiously, but the movement was still enough to jostle her injured shoulder. Tch. A single brown eye cringed. She prayed that it wasn't too serious. Experimentally, she rotated her shoulder, oblivious to Reborn who was observing her with Leon-binoculars from one of his hiding places.

The baby smirked, already beginning to plot.

"Ow..." she breathed out, only mildly relieved her arm hadn't popped out of its socket. It still hurt like hell though so she couldn't say she was too grateful.

"You..." a cold voice started. Hm...? She looked up through the stray strands of dark brown hair and found a dark-haired boy glaring at her. She managed to put two-and-two together of why he seemed so angry.

"Erm," she pointed to the flaming tree. "That wasn't my fault." She realized either that wasn't the reason for his disdain or that he didn't believe her when he held up the weapons in his hands. She was flabbergasted to find it was neither.

"What is an unauthorized person doing on the school grounds?" He was slowly walking up towards her.

...

...His priorities are a bit out of whack, she thought mildly. Burning tree or stranger on school grounds, hmm... Still she answered, annoyance creeping up in her voice. What a way to start her first unofficial day as a student.

"I'm not unauthorized," she replied courteously. The girl heard a sound to her side and saw the short boy was wheezing from breathing in the fumes. The taller boy was unhelpfully thumping him on the back.

"But," her gaze shifted nervously at the roaring flames engulfing the tree. "Don't you think you should be more worried about that tree over there?"

Hibari aimed one of his tonfas at her face.

"Ah!" The barely managed to dodge and fell ungracefully on her butt. Her mouth was set in a tight line as she recovered.

"G-guess not." She scuttled back. She didn't want to be maimed by the very, very violent boy. He honestly believed she was trespassing.

Even though I'm honestly not! she thought.

"Anyone who comes into Namimori without permission..." She gulped. His eyes were filled with a light not entirely sane. She felt something under her hand. It was her student record. Her mind worked quickly to analyze the last few moments. This boy was most likely from that committee. That was the only reason she could come up with as to why he was angry. So that meant she needed proof that she wasn't trespassing. Her clammy hands quickly snatched the profile.

It's all really a matter of speed now, she thought morosely as she watched him raise his weapon in the air.

"...will be bitten to death by me," he finished. Hibari's arm swung down in a wide arc at the foolish herbivore who dared to intrude into his school, his territory.

...

Hibari frowned. The girl was obstructing his vision with papers presented right into his face. He snatched them from her shaking hands and skimmed through them. She sighed in relief at the brief moment of reprieve. She got up and patted off the dust on her clothes as he read. She looked at his face to see him frowning not from anger, but from... He looked... disappointed? She crossed her arms as anger overrode fear.

Sick sadistic bastard! Hibari looked at the record and then at her. She stiffened. Had he read her thoughts?

"Looking a little young, aren't you?" he simply said and then turned off on his heel, her student record in hand.

Her cheeks burned.

Dammit, dammit, dammit!

She heard an authoritative squeaky voice call amongst the chaos. "Sakata Masami."

The girl, Masami, looked up long enough from inspecting her shoulder to see a small baby in front of her. "Oh..." What was proper etiquette when speaking with a talking baby? "Hello..." She settled for that, nice and safe. He walked up with a peculiar confidence in his step. Completely black eyes blinked up at her. She blinked back.

"Would you like to join the family?" He smirked. "Your bravery could be needed in the future."

Eh...? Her response was interrupted by a loud shriek.

"Reborn!" The spiky-haired boy had finally gotten himself pulled together. He walked up to her and the tiny baby, the other boy following closely behind. For some reason or another, the silver-haired boy was glaring at her. She waved a small hello and flinched back when he growled.

"I told you not to try to recruit any more people into the mafia!" Tsuna exclaimed.

Mafia...

Masami could only watch in shock as the baby jumped to an impressive height to kick the boy in the face. The silver-haired boy seemed just as surprised. His cigarette dropped out of his mouth as his jaw dropped.

"No-good Tsuna, go thank Masami already." Reborn kicked the weak boy, Tsuna, in the stomach again, completely ignoring Tsuna's sentiments. "You've reached a new low by receiving help from such a tiny girl." Tsuna seemed to deflate from the height jab. Reborn was right. He'd been saved. By a girl. She felt pity.

"If it makes you feel better, I think I'm an inch taller than you," Masami offered. It didn't help at all. Like a wilting balloon, Tsuna only deflated more on his position on the ground. "EEK!" He shrieked as Reborn kicked the side of his head. Masami didn't know who to feel sad for: Tsuna who was on the ground crying or Reborn who truly seemed disappointed.

The girl shook her head. "It wasn't a problem." She grinned at the three pairs of eyes. Tsuna's eyes reflected gratefulness at the grinning girl.

"M-Masami-san." He looked down, manners from his mother dictating he use the polite '-san'. He was confused why he was embarrassed. She looked younger than him, barely 12. She was most likely a little sister of one of the Namimori students, so why the heck was he blushing? Her eyes... Maybe it was something about the light of the inquisitive doe-like eyes searching his face.

"Thank you for your help!" He bowed down humbly. He ignored Gokudera's outraged "Juudaime!"

Masami smiled. "It really was no problem at all," she promised them. Masami perked up upon hearing the bells of the school clock, signaling the next hour had begun. "I have to go," she said, holding her hands together in front of her apologetically. She was gone before anyone could say anything else.

"I wonder if we'll see her again..." Tsuna wondered out loud. He felt guilty that all he had managed was a simple thank you.

Gokudera snorted. "That woman..." He spit on the ground violently and began to light another cigarette. "She saved the Juudaime before me!"

Tsuna gaped. I-is he complaining?

"We will," Reborn assured. "She'll be an official student at this school tomorrow, after all."

Tsuna's jaw dropped. "EH? Really?" He looked at Masami's retreating figure. "She looks so young though... I thought she was at most 12," he admitted sheepishly. She was a little taller than him, but... even he had to admit he was kind of on the short side...

One blow to Tsuna's self-esteem: check.

Reborn didn't answer. The Arcobaleno stared at slowly disappearing girl. More specifically, at the shoulder injury.

"Wait." Gokudera looked at the Arcobaleno. "How did you know her name, Reborn-san?"

Reborn shrugged. "I have ears around this school," he said vaguely.

Tsuna's jaw dropped. "YOU WERE IN ONE OF YOUR HIDING PLACES AGAIN, WEREN'T YOU?"

Hibari gazed out of the windows of the Reception office. He had already gotten his members to deal with the burning tree and had specifically ordered them to toss out the useless vegetation once they put the fire out. Hibari spotted something. He narrowed his eyes at the ground below.

That girl... Hibari watched disinterestedly as the figure walked towards the entrance. The weakling herbivore stopped suddenly. Hibari's eyes widened as she turned her head towards his direction. She chanced a secretive smile at the head prefect before dashing off.

Hibari gave a small smirk.

A/N: Thanks a lot for reading and please review if you liked it. I would like to know what everyone thinks of the OC. (:
