Disclaimer: I don't own Katekyo Hitman Reborn. All I own are my OCs.
Rating: T; swearing, bullying...unjustified killing of random poor OCs. Who have around 3 minutes of appearance time in this fic. I hope nothing has become too violent...

A/N: DOUBLE UPLOAD! Sorry TT^TT I couldn't help it...

Okay! Sorry for any confusion, but time is starting to get screwed up royally in this fic. The italics are what is happening to the ten years later characters, sorry for any confusion. But I guess if you read this chapter, you'll understand...I hope anyway XD

Company

Hibari looked into the mirror, tightening his tie one last time. Behind him, he could hear the Tenth Vongola boss freaking out about something again, as per usual. Dino Cavallone was with him, trying his best to calm down the panicking Vongola Don.

Today was the day when Tsuna was getting married to the girl of his dreams. Sasagawa Kyoko was all dressed up in a beautiful white dress for the big event, her friends Haru, Hana, Ipin and Chrome were all behind her, helping her fasten the traditional white train to her dress. Hibari glanced at the five of them, and felt a pang in his chest.

He couldn't help but wonder what it would've been like if Kumiko were still here. She would be there with the girls, giggling at how beautiful Kyoko looked and twirling in her own bridesmaid dress. She would be pouring drinks with Yamamoto, trying her hardest not to spill a drop. She would be worriedly combing Tsuna's hair, saying that it's too poofy. She would be arguing with Gokudera about whom should be the one playing the wedding march, and then they'd finally settle on doing a harmonious duet.

She would be next to him, tightening his tie and reassuring him that the wedding was going to be fairly quick, and that she would leave with him before the party afterwards if he wanted her to. She would be casting worried glances between him and Mukuro, trying her hardest not to yell at Mukuro to stop staring at her, because she's taken.

He turned away and focused on brushing away minute specks of dust on his suit. Mukuro leant on a wall across the room, staring at the ground at his feet. Hibari knew that Mukuro was thinking of her too.

The wedding passed in a blur. Hibari himself played no big part in it, only giving a brief nod of approval when the couple stood at the alter looking proudly at the audience. Immediately after the couple were declared husband and wife, Hibari left. Kusakabe was waiting outside for him loyally, and Hibari slid smoothly into the car. Kusakabe pulled out of the driveway without even being told where to go. He knew Kyo-san way too well.

Upon reaching the Japanese section of the Vongola Base, Hibari wordlessly slid the door open and strode in. Quickly changing into his yukata, he sat by the window, not saying a word. And he stayed there for three hours, just thinking of her. Of what they could've had. Eventually, he fell asleep, dreaming of her lips on his, her hands stroking through his hair comfortingly.

"I'll never leave you." She'd promised.

Liar.

As the weeks passed, Kumiko became closer to Komatsu, or so she thought. Komatsu started hating the clingy girl. She seemed to be starved of human interaction or something, because she followed the taller girl everywhere. When Komatsu wanted to go to her locker, Kumiko would follow her gladly. Even when Komatsu needed to go to the bathroom, she'd always walk out to find that Kumiko was sheepishly waiting outside for her.

She hated her.

And her hate festered in her heart. She was an assassin, damnit. Not some sort of idol this girl should be following around. She was a paid killer, not some sort of girly best friend for this 'kicked puppy' like girl. The only escape for her was thinking about how they would use her. Nakamura told her that she only needed to keep up her act for a few more days, and then they would put the plan into action. Everything was set in place.

Just a few more days, she promised herself. And then Kumiko would probably be gone from her life.

Hibari opened his eyes, only to close them immediately again. The noonday sun was shining right into them, almost blinding his eyes with the sudden brightness. He groaned upon feeling his head hurt from even that small amount of exposure. Sitting up with his eyes still closed, he made sure to cover his face with his hand so as not to blind himself once more. Cautiously flickering his eyelids, he realized that he could now see properly again. The first thing he noticed was that he wasn't back in his room anymore.

"Time travel", he muttered to himself. Now, of all times...

The second thing he noticed was that his surroundings were unbelievably noisy. It's like multiplying Sasagawa Ryohei by 30 and then telling them to challenge each other to a boxing showdown in his very own Japanese styled living room.

Hibari groaned once more. His headache increased with the cacophony of strident noises.

The third thing he noticed was that he was in Namimori Chuu of ten years ago.

Kumiko bounced impatiently as she waited for Komatsu to fetch her school books. Honestly, the taller girl was so slow sometimes. Komatsu had her back facing the brown haired girl, and was scowling openly into her locker, resisting the urge to turn around and throw a punch at the idiot behind her. Inhaling a deep breath, she plastered a smile to her face and turned around.

"Okay, let's go!"

The girl's face fell for a second upon seeing her fake smile, and Komatsu couldn't help but wonder whether she was really as clueless as she let on. Her worries trailed off when Kumiko laughed at the face she made. The smaller girl was once again back to her normal, excited self. She took Komatsu's hand in hers and dragged her to the cherry blossom trees. Sitting down first, Kumiko patted the ground beside her and started opening her bento. Komatsu obligued and opened her own.

Hibari watched as the two girls sat down. He narrowed his eyes dangerously. He knew both of them. His beloved Kumiko and...that assassin. Letting out a snarl, he drove his tonfa towards her head. However, it didn't do anything but pass through her. Kumiko, sitting next to the Silent Slayer, shook her head, confused. Hibari found himself looking straight into her eyes as she looked up, almost as if she could sense his movements but couldn't see him. To test it, he called her name.

"Kumiko."

Kumiko blinked once more. Someone called her? Someone...

Hibird fluttered out of nowhere. "Hibari! Hibari~" the little bird supplied melodiously. Kumiko looked around, but Hibari-san was nowhere in view. Komatsu took on an expression of annoyance at the bird and excused herself quickly. Kumiko could only nod absentmindedly, intent on finding the source of the name calling once and for all. She wanted to stop feeling so insecure, what with the head prefect bullying her randomly and now the ghostly name calling.

Hibird hovered around Ten Years Later Hibari's face, chirping happily.

Hibari held up a finger, and smiled when Hibird landed on the finger gently. The animal could sense him, of course. Animals' perceptions are always sharper than humans. Stroking it's head, he watched as the bird rubbed itself against his fingers gleefully. Suddenly, the bird fluttered off quickly, causing Hibari to raise his head. Spotting a movement in the third floor of the building, he quickly ducked behind a tree. He felt his movements start to slow down, and the panic in his chest started to rise. His younger self must've seen him.

One thing you mustn't ever do when you time travel: To let your younger self see you. Otherwise...

Time lapse, begin. 5:00 minutes to combustion.

The world will blow up.

Time to leave, Hibari thought to himself. While I still can move, anyway.

Hibari threw open the window of his office, reveling in the breeze that swept through the room. It was getting too stuffy in there. He caught a familiar movement between the cherry trees in the front courtyard of the school and glanced casually out of the window. Ten Years Later Hibari stared back at him with an edge of panic in his eyes, before quickly moving out of the line of sight. Hibari growled. He still hadn't paid that man back for what he did to his face! Even if it was himself, that strike was totally unjustified.

So he turned to hurry down to the courtyard and battle his older self. But the more he moved, the slower his movements seem to get. It was the same feeling he'd gotten when he'd watched the older him kill Kumiko by the riverbank. The feeling of being stuck, slowed down. It was as if time was stretching out...

"Ciaossu." Reborn called out to the struggling prefect.

"Baby." Hibari began, calming down, but only slightly. Reborn stared out the window, frowning at the view before him. Ten Years Later Hibari was also struggling to move, but he was making much more progress than Hibari had in the office. Possibly because he was use to this situation.

He disappeared, and suddenly Hibari was free again. He took out his tonfas and swung them around to test his mobility and was pleased to say that his movements were back to normal. Reborn stared silently at him before speaking once more.

"Hibari, do you know what just happened?" Reborn started.

"Hn?" Hibari sat down and looked away, but Reborn knew that his indifferent act was just another way to show that Hibari was hanging on to his every word. Reborn smirked.

"Your older self knows. That's why he left immediately without doing what he wanted to do."

"And what was that?"

"That's for me to know and you to find out, Hibari."

"Hn."

"What you've just experienced is something called Time Lapse. Hibari, you can travel through time. Right now, you have minimal control of your abilities, but your future self can do so sufficiently, at least enough to quench his own desires."

Hibari looked up at the infant's words. Time travel? That's insane. He didn't believe in such superstitious things like that.

"Don't believe me? You got hit by Lambo's bazooka before, didn't you? What happened then? You travelled to the future, didn't you?"

"That was with the help of scientific equipment. It doesn't justify for supernatural abilities."

Reborn tapped the brim of his fedora thoughtfully. Truth be told, it was rather hard to convince Hibari otherwise, and yet he could understand the feeling. If someone were to tell him that he could time travel, he would've laughed in that person's face and then he'd probably put a bullet through their idiotic brain. It was good enough that Hibari hadn't walked off already. Suddenly, the perfect example came to his mind.

"Your tonfas, Hibari. When you take out your tonfas, what does everyone else do?"

"Freeze in terror. Run away."

"Yes, they freeze, like a delayed reaction, before they run away. Don't you find it weird?"

"No. They're herbivores. They're scared of me."

"Hm. Where do you take your tonfas out of?"

Hibari pulled a collapsible tonfa out of his sleeve, glancing sideways at the Acrobaleno's reaction. Reborn kept his face carefully blank. "So they come from your sleeves. When you take them out in preparation for a battle, you pause time ever so slightly so that it seems like you're pulling them out of nowhere. I've heard Dame-Tsuna complain enough times that your 'magic tonfas' come out of nowhere, so don't deny it."

Hibari's mouth curled into a humorless smile. So what if he could control time flow for himself?

I could have an advantage in battle. I can fight difficult opponents again and again until I bite them to death effectively. I can...

Go back and beat Mukuro.

A slow sadistic smile made it's way across his face. He faced Reborn once more. "So tell me, baby. How can I hone my...ah...abilities?"

Reborn smirked. "Don't be so quick to think ahead Hibari. Mukuro can control time too. And much better than you, well, right now anyway."

Hibari went back to scowling. Damn that pineapple illusionist.

Komatsu looked into the mirror, combing her hair backwards with her hand. She swears that some white hairs have developed because of that stupid girl. Venomously, she took out a backup knife which she kept strapped to her back, and stuck it into the sink drawer. She imagined that it was Kumiko's flesh, and that blood was pooling out of the wound right now, and dripping onto the tiled floor.

"Tsubaki-chan?" A girl asked hesitatingly. Komatsu whirled around, effectively hiding the knife from her view. She smiled.

"What is it, Amane-chan?"

"Ano...what was that behind you? I saw something like a knife...something..."

You know too much, girl.

"Don't move. It's actually a surprise for the class. A magic trick. Do you want me to show it to you?"

The girl's eyes widened in delight and she clapped her hands happily. "Okay! I won't tell anyone, promise!"

"Close your eyes." The Silent Slayer ordered and the girl complied readily.

With a yank, she pulled out the knife. All these weeks of frustration and anger towards one girl, Koizumi Kumiko, was going to be released in this single moment. Nobody would ever have to know, least of all Nakamura. She was still a teenage girl after all. She needs some kind of vent for her bottled up feelings.

And for her, the vent wasn't crying. It was killing.

Lunging forward, Silent Slayer wrapped her arm around the girl's mouth. Amane snapped opened her eyes in surprise, completely confused at the change in situation. The hand around her mouth tightened, and suddenly she was finding it difficult to breathe. She struggled open her mouth and chomped down on the offending hand. Silent Slayer didn't move, and Amane realized that the girl was wearing gloves. She was starting to see black.

Silent Slayer hurled her against the wall, her hand never leaving her face. Once pinned, she took out the knife and slid it teasingly across the girl's skin. She was crying now, her tears rolling down in fat drops and splashing onto the porcelain tiles below. Silent Slayer held no compassion for her victims though. She didn't even feel guilt for all those she'd killed in the past. Even if this kill was of her own accord, nothing had changed.

She was about to stick the knife into the girl's chest, but then realized that it would be too much of a messy ordeal. Unless...she burned the wound close before it could drip?

So she plunged the knife in. Amane's eyes widened for a second, and a muffled scream ripped out of her throat. Silent Slayer held her hand firmly against her mouth, and nobody heard the scream. She left the knife in the wound, and then drew her bloodied hand back. The hand burst into flames, and the blood evaporated and the knife melted, leaving no trace of weaponry behind.

Sky flames. Silent Slayer uses sky flames.

And those harmonizing flames, warm as they are when used for a good purpose, were pressed coldly to the girl's chest, effectively burning the wound close. A glaze of death came over Amane's eyes. She was well and truly gone. Silent Slayer decided that she wanted to get rid of all the evidence, and she let the body crumple to the ground before striking her still burning hand against the corpse's clothes.

She watched happily as the girl's body went up in flames.

A/N: Read and review, everyone! I would really appreciate it if you dropped in a small sentence or two on how I'm doing with this fic.

Pretty, pretty please? I might even upload faster! ^.^
