OK..this is my first KHR fic, I've written others but KHR this is the first!

I do not own Katekyo Hitman Reborn, all characters belongs to their respective owners!

"Are you sure about this 9th-sama? This position has been kept a secret for years...revealing it now will cause quite a commotion." a girl hiding in the dark corner of the office has spoken.

"Yes...This is my final decision, besides, aren't you tired of keeping yourself a secret from the rest of the Vongola Family? I promise you, you will enjoy being with Tsuna and his guardians..you need to get used to their presence if you want to be a proper addition to his guardians" the 9th boss of Vongola Family has assured the worried girl with a warm smile.

"Alright....If this is what the 9th-sama wishes.." she left the room with half a smile.

"Good luck Riza-chan." he muttered to himself.

NAMIMORI MIDDLE

"YAAAAAAAAAAAAAWN" I'm so sleepy! Tsuna yawned tiredly.

"HAHAHA! You yawn really big~" Yamamoto chirped in response to Tsuna's lazy yawn. "You're so lazy..Hahaha!"

*WHACK!*

"Your the one to talk! You baseball nut!" Gokudera yelled frustrated to the carefree idiot.

*DING! DING! DING!*

The teacher entered the room and all the students went back to their seat.

"Ehem! Good morning class, today before we start our class, we have ANOTHER new student, she moved from Italy and will be studying here in Namimori middle..." the room buzzed in conversation. "Another? From Italy?Italians must really love Nami middle..what so great about this school?" the teacher fashed a glare, the student fell silent.

"Come on in and introduce yourself to the class.." the teacher called out.

SILENCE......

"Uh..I said you can come in now..theres no need to be shy." the teacher repeatedly called the 'New Student' but like before nobody came in. This time, he went outside to call her but was only greeted by an empty hall..."Huh...I wonder where she is?"

MEANWHILE...

"CRAP!! I'M SOOOOOOOOOOOOOOO LAAAAAAAATUUUUUUHHH!!" a girl in Namimori middle uniform ran as fast as she could, it was already past 8:00. "I can't believe I'm late on my first day!" she ran as she ate her break fast, brushed her teeth and tied the ribbon of her uniform.

As always, Hibari stood by the gate waiting for any students that are late, threatening them, or 'Biting them to death'. Fortunately for him, his wait was not too long, he could hear his 1st victim for the day and he was beginning to see the running student. From afar, it looked like a stampede of bulls, creating a cloud-like dust trail. "I'M SSSSSSSOOOOOOO LATE! UNFORGIVABLLLEEE!!"

"Your late!" Hibari pulled out his tonfas to stop the rampaging student. When he noticed that this student wasn't about to stop, he stood in a defensive stance.

"GET OUT OF THE WAY OLD MAAAAAAAAN!" the girl yelled and ran past him, knocking him down his feet. Frustrated, Hibari got up to his feet and ran after the student.

"She called me old man......I'll bite her to..death!"

"I'm SORRY I'm late!!!" the girl slammed the door open, panting, trying to catch her breath.

"So you finally decided to show yourself up.." the teacher said annoyed.

*TOINK* she hit herself in the head. "Sorry! I overslept!" she smiled and bowed to the class.

"My name is Riza Tanakuse! I'm from Italy and nice to meet you!"she said cheerfully.

the class was silent, it happened so fast that they didn't really catch her name.

"Why don't you go ahead and sit next to Yamamoto..." she looked into the class to see a idiotic-looking guy waving and smiling at her. "Konnichiwa Yamamoto-san!" she smiled.

*DING DING DING (LUNCH TIME)*~~~~~~~~~~

"What did you say!?" Gokudera's frustrated voice rang in Yamamoto's head.

"Ahahahaha! You're so loud, and you turn really red when your angry! Ahahaha!" he chirped.

"I'm gonna blow you up to pieces you baseball nut!!!" Gokudera pulled out his handy-dandy dynamites and was about to throw them to Yamamoto but Tsuna stopped him in time.

"Come on you guys! No fighting! Fighting over stupid things!"

Lunch time has always been so loud and noisy for Tsuna's group, carefree and have no care as long as they're together, but little do they know, they were being watched form afar.

"*sigh* How am I gonna approach them? 'Hey my name is Riza, I'm from your class and I'm here to kill you!' GAH! that was lame.." Kill? Her insticts tells her to kill, wonder why?

*Sigh* She grabbed her bento box from her bag and sat on the highest spot of the Nami middle rooftop. "I really need to figure this out," she took a big bite out of the onigiri she packed.

"GAAAAAAAAAH!! I REALLY NEED TO TALK TO THEM!!! " she screamed out loud, scratching her head in frustration.

"Oi..you're too loud, do you know what happens to people that disturbs my sleep?"

She continued to eat her box lunch as she mumbles to herself ignoring the familiar voice behind her.

"Maybe I can go with the shy approach.." she said to herself, meanwhile, Hibari is fighting to control himself from biting the girl in front of him. "OI! did you heard what I said!"

"AH! Maybe..I can just tell them who I really am!"..Hibari..IGNORED *snap*

"I'll teach you not to ignore me while I'm talking to you!" Hibari pulled out his tonfas and attacked the girl from behind. The girl dodged his every attack with out looking or moving from her sitting spot. Her hands still holding her box lunch, eating and still muttering to herself. "I can't really say 'that!' first I gotta prove them worthy!" she said with a bright smile as her eyes glittered in delight. Out of insticts, she lifted her chopsticks to her side, it caught something hard but she ignored it and tossed whatever she had caught..*WHOOSH! CRASH!*

What was that? she looked down from the spot she was sitting on. There was a figure laying down face flat on the floor. "Hey...are you alright?" she asked. The figure slowly got up, there was a 'I-will-kill-you-til-you're-torn-into-pieces atmosphere' and it gave her the chills. "What are you doing down there? That's no place for a student to be sleeping!" The atmosphere worsen, she could see how dark it got around the figure.

"I will bite you to death!" he muttered his voice trying to sound calm.

"HEEEEEEEYYY! you're that old man by the gate this morning..OH! You're not old! I guess I'm sorry! Ahahaha!" she chuckled ignoring the killing atmospere, she don't seem like she's afraid of him.

Without further talking, the figure jumped up and attacked her with his Tonfas..swinging it like a mad man, he has no proper style but he's good, fast and strong..she figured it right away who that man is.

She smiled a bright smile, "I'm Riza Tanakuse!..Its nice to meet your acquaintance...Hibari Kyouya-san!" His never-breaking nerve quaver for a moment to find out that this girl he was fighting knows him yet he knows nothing about her. Interesting.

Like him, she was able to stay calm as Hibari tries to hit her, failing to make a hit, Hibari changed his pace, he started to move faster. small square holes opened on his tonfas revealing sharp spikes. The same as before he was unable to give her a good beating..and he's having fun fighting this strange girl. She stopped dodging and stood in place, waiting for Hibari to get closer. The tonfa made a whooshing sound as Hibari swung it to his right, but then it was stuck...Stuck? no It can't be stuck, they're in the middle of the roof with no wall around them..then how can...

Hibari turned his head around to see Riza holding his tonfa with her bare hand, despite the spikes and her bleeding hand, she was able to keep an unnerving smile.

"Yare yare....Lets put this away before somebody gets hurt..or worst..you." She pulled the tonfa dragging Hibari with it towards her, their faces inches apart.

"Let's end this shall we?!" and with a swift kick in the gut, she made Hibari flew across the other building of Nami middle, where Tsuna and his friends were gathering.

"HIEEEEEEEEEEE!" Tsuna squeeked in surprise when he heard a loud crash behind them. They ran towards the spot, only to see Hibari half concious on the ground.

"Hibari-san! What happened?" Tsuna asked him worried.

"......" no response from him, he merely got up to his feet, his tonfas in hand.

"Is he fighting someone?" Tsuna asked.

"Oi! Hibari!" Yamamoto called out but Hibari kept on walking.

"Ohohoho! you're still alive?..." Riza stood on top of the thin fence that surrounds the rooftop. "Sorry, I didn't mean to hit you that hard!" she jumped down. "Forgive me! Forgive me! FORGIVE MEEE!!! ITS UNFORGIVABLEEEE!!!!" she quickly apologized to Hibari kneeling in front of him him, bowing, letting her head hit the ground hard repeatedly.

"Now..where did we see that before?" Reborn said as he looked at Gokudera.

"Get up!" Hibari glared down at her, but she ignored him, silently bowed down, not making any eye contact.

"Hmph!..."Hibari walked away, he got tired of the girl...but an interesting one.

"WHEW! he finally left!" Riza got up relieved.

"Y-You're Riza-chan from class! were you fighting Hibari-san?" Tsuna asked.

She shook her head. I'm not really fighting him..i think..I was just trying to dodge him..Hey you're Tsunayoshi Sawada!" she was about to approach him, but Gokudera stopped her, dynamites in hand.

"Alright, cut the crap! Who are you?!" there was a defensive tone.

"...oh..uh..oh no..should I tell them?..Uh what should I do?...Um..I." she mumbled to herself twiddling her fingers like a shy middle school girl. this frustrates Gokudera more.

"Ahahahaha! Come on now Gokudera-san.."

"Shut up you baseball nut! What if this girl is here to assassinate the 10th?!"

"OH NO! I WOULDN'T DO THAT! not to the 10th anyway!..."
"Well what are you here for?!"

"I'm Riza, the secret guardian of the 10th boss of the Vongola Famiy...I'm the Night Sky Guardian! I know its lame but...I'm here to provide help to the future boss. NICE TO MEET YOU!"

"EEEEEEEEEEHHHHH?" they all said in unison..
