--------------------------------------------

-Normal POV-

Naria woke up to her mother calling her down for breakfast. She quickly got dressed and rushed down to the kitchen, where her mom was making breakfast and her father was reading a newspaper.

Her mother, Aria had black hair and onyx black eyes. While her father, Mizuo had brown hair and red eyes. Naria inherited her mother's black hair and her father's red eyes.

"Morning, Mom! Morning, Dad!" she greeted with a smile.

"Good morning Naria! How are you?" asked her father.

"I'm feeling great, Otou-san!!!" she cheered.

"Are you excited for Aunt Michiru and Uncle Kisuke's visit?" asked Aria, putting the cooked eggs on a plate.

"Are they bringing Tadaomi too?!" Naria excitedly asked.

Michiru Tsukuyomi is Naria's mother's older sister by only five years. Kisuke Karasuma is her husband and Naria's uncle. Tadaomi Karasuma is her cousin, though he is only slighly older. Tadaomi treats Naria like a sister and is currently wanting to become a Government Assassin, when he's a bit older. While there was some protest on what he wanted to become, his parents supported him anyway, cause once Tadaomi sets his mind to something, he's gonna push himself until he accomplishes it.

Tadaomi also had a little sister, around Naria's age. Her name was Hoshi, and to be honest, she was the most adorable, innocent person she's ever known. Which explains why Tadaomi is so overprotective of his little sister. Hoshi is usually home schooled, due to overprotective brother, who managed to convince his family to let her be home schooled....somehow....

"Yes, Tadaomi and Hoshi are coming too. Tadaomi says they're not busy, so they can stay for about a week." answered Mizuo as his daughter cheered.

As Naria was eating her breakfast, she suddenly remembered that she and Tsuna were walking to school together! She looked at the clock, only to see 7:34 AM!!!

"I'M LATE!!!"

Quickly finishing her breakfast, Naria raced out of the house yelling her goodbyes to her parents. She dashed off to the direction of Tsuna's house, while fixing her shoes in the process.

Staring at the direction that their daughter was running, the parental couple laughed at her antics.

---------------------------------------------------
-Sawada Household-

Naria barely made it to Tsuna's house, she made it just as Nana was finished making Reborn some pasta. Bianchi and Lambo were also there, with Lambo already making a mess.

"I'm sorry for being late!" gasped out Naria, who was out of breath from running.

"Oh you're fine Naria-chan! Tsuna just woke up not too long ago." replied Nana, giving Reborn some pasta. 

"Morning Reborn, Bianchi!" she greeted the two hitmen cheerfully. 

"Ciaossu Naria!" came the infant's signature greeting. 

The dark haired girl gave a small smile, and then felt something tugging at her leg. Looking down, Naria saw the little cow of the household, Lambo, hugging her leg. 

"Nari-neechan! I wanna play!" said Lambo, but before he could say anything more, Reborn tossed a rubber ball at Lambo. 

Apparently, Reborn had tossed it so hard, it sent Lambo flying right into Tsuna, who just came down the stairs. The impact of Lambo hitting Tsuna in the gut was enough to knock Tsuna off balance and fall down the stairs. 

"WHAT THE HECK WAS THAT FOR REBORN?!" yelled Tsuna, holding up Lambo so he could talk. 

"You're being slow Tsuna." replied Reborn, then gestured to Naria. "Your friend is already here." 

Scrambling along, Tsuna grabbed a piece of toast from his plate and ran out of the house with Naria behind him, both shouting a farewell to his mom. Nana waved back a smile on her face, wishing them a good day. 

As the two best friends ran along the street, they fail to notice Reborn following them. Naria mentioned that her aunt and uncle were coming over by the end of the week for a visit. Tsuna, having met them before, stated that the elder of the two, Tadaomi was scary, considering that his smile even scared tough dogs. 

"You need to learn how to stop being a whimpering cat, Tsuna." came Reborn's reply from atop a stone fence. 

"HIIE!" squeaked the brunet. "R-Reborn!" 

Before the infant could speak anymore, a girl with dark brown hair made her way up to them...by balancing atop the same fence that Reborn was on. 

"Hello!" greeted the girl, mostly directed towards Reborn than the two teens staring at her.

"Ciaossu!" greeted Reborn. 

"My name is Haru Miura!" said the girl, trying hard to keep her balance. 

"I know." replied Reborn. "You often tag along when we're going to school. What do you want today?"

"Eh, really? I never noticed." wondered Naria, looking back and forth between the two individuals on the fence.

The girl, Haru found Reborn adorable, wanting to hug the infant hitman, however, said infant refused and transformed Leon into a green gun, stating that he is a hitman. In response, Haru turned to Tsuna and straight up slapped him. 

The dark brown haired girl then went on a rant, questioning what Tsuna was teaching this baby and that babies are pure angels who are young and innocent and that Tsuna was destroying that said innocence with his rotten heart. Though in their opinion, Reborn was anything but innocent.

"I-I don't think he knows what you're talking about Miura-san..." said Naria, trying to separate Haru and Tsuna, who is being shaken by the brunette girl.

"Wh-What's going on?" questioned Tsuna, tears running down his face.

Thankfully a familiar laugh distracted the three teens, as Lambo came swinging in, literally, in another attempt to assassinate Reborn. He stuck both of his hands into his afro and pulled out two pink grenades. Unfortunately, this caused him to let go of the rope and he fell down, luckily, Naria caught him. 

"H-Hold it in...." stuttered Lambo, tears gathering in his eyes as he gripped Naria's shirt sleeve.

"There there Lambo, it's okay." comforted the red eyed girl.

Haru had let go of Tsuna to walk over and picked up Lambo from Naria's arms.

"Oh my, are you okay little boy?" she asked the sniffling Lambo, who stared at her in confusion.

Then she noticed how adorable the cow was and began to hug him, squealing about how cute he was, but Lambo didn't seem to think the same way.

"Th-This hurts..." the five year old gasped out. "H-Hold it in..."

"Um Miura-san, I think you're hugging him a bit too hard..." Naria said noticing Lambo's lack of air, but then noticed that there was a lack two other presences. 

Naria turned to where Tsuna and Reborn were supposed to be, only to find them gone.

"Eh?" she questioned before looking at the time on her watch. "I'm almost late! Sorry Miura-san, Lambo-kun, I have to go!"

With that, the blackette ran off in the direction of Namimori Middle School, barely making it into the classroom when the bell rang.

Well at least that she didn't have to deal with Hibari today.

When it came time for their math class, they were just getting their math test scores back. 

"Gokudera, Hayato. You scored a 100 on the math test." said their math teacher, giving Gokudera his test back. 

"Whoa!" was the class' collective response. 

As Gokudera went back to his seat, Tsuna praised the silver head, who tried to shake it off as nothing. 

"Tsukuyomi, Naria." called the teacher, with Naria standing up to get her test. "You scored an 87 on the math test. Not bad, but there is room for improvement." 

Naria bowed, taking her test and sitting back down. Tsuna turned in his seat and gave his friend a thumbs up, which was returned with a smile and a thumbs up in return. 

"Sawada, Tsunayoshi. Yamamoto, Takeshi." called the teacher again, with both boys standing up at the sound of their names being called. "20 points. A failing grade means that you'll be assigned special homework."

Tsuna looked away embarrassed, his cheeks red.

"It's due tomorrow, you must get every problem correct or else." explained the teacher. 

Right after that, the bell rang and school was over. 

As Tsuna was packing up, Naria walked up to his desk. 

"Tsuna, I can't come over tonight. Mom wants me to come home straight away to help clean the house." she told him, adjusting her bag. "Since my relatives are coming, we need to clean the house."

"It's fine, I'll try my best to do the homework." Tsuna said as he stood up, finished packing up.

"I can at least walk you halfway." Naria said.

So the two friends were walking down the neighborhood, though Tsuna did look a little down. As they were walking, Yamamoto managed to catch up to them. 

"Yo Tsuna, Tsukuyomi-san." greeted Yamamoto, patting Tsuna's shoulder.

"Yo Yamamoto-kun." Naria greeted back as the two turned to greet the baseball player. "What's up?"

"I wanted to ask Tsuna if we can work on the homework together. After all, with two people it might go by faster." explained Yamamoto.

"Let's do that!" Tsuna agreed, a bit happy that he had help.

"Okay then, do it at our place." came a familiar squeaky voice.

Lo and behold, Reborn showed up, as a plant in front of a house. While Tsuna was freaked out, Yamamoto took it casually and greeted Reborn, who replied with his signature, "Ciaossu."

While Tsuna argued with Reborn, Naria checked the time on her watch and then turned to look at the situation at hand. Apparently Reborn also called in Gokudera to help out. Yamamoto laughed along while Tsuna exasperatedly agreed.

Beside the two, Naria chuckled, "Well you two better head on to Tsuna's house then. I have to go."

Waving bye to the two teens, Naria ran off towards her house. 

--------------------------------------------
-Later That Day-

After long hours of cleaning the house from top to bottom, Naria collapses on her bed, tired after the long day. However a sudden ringing snaps her up, it was coming from her cellphone. Checking the caller ID, Naria noticed that it was Tsuna who was calling her. Answering the call, Naria was greeted with Tsuna screaming for help, which caused her to pull the cellphone away from her ear.

Finally getting her hearing back, the blackette responded, "Tsuna, slow down! I can't understand what you're saying?!"

"Please help me on this one question!" the brunet begged from the other side of the phone line.

"What's the question?" she asked. 

"Prove that when 100 sheets of paper, 11.5 centimeters long on each side will stack up perfectly when dropped from a height of 3 meters." 

"Hmm," muttered Naria thoughtfully. "Have you ever considered that the papers could be bound together? Or glued?"

"Uh..." was Tsuna's hesitant reply.

"Ask Reborn, maybe he know. Good night." with that, Naria hung up and fell asleep, not wanting to deal with more shenanigans until tomorrow.

However, just before she fell asleep, Naria sensed something from outside her window. Snapping her eyes open, she looked towards her window into the dark neighborhood. The presence felt like someone was watching her, but she couldn't tell if it was benevolent or malicious. Narrowing her red eyes, Naria closed her curtains before returning to bed.

Far away, a figure stood on a building deep in the shopping district. The figure was short, and an artic fox stood beside them.

"So this is where Reborn went..." 

--------------------------------------------
-Timeskip-

The next morning, Naria walked over to Tsuna's house so that they can walk to school together. As she walked up to the house, Naria noticed that there was something there, hidden by the neighbor's house, however she was quickly brought out of that by Tsuna stumbling through the door. After saying their greetings, the two friends headed off to school.

So how was the homework last night?" Naria asked, curious about what happened. "Did Yamamoto-kun and Gokudera-kun help you out?"

"Yesterday really sucked." was Tsuna's blunt reply, yawning right after. "Question 7 was a pain, and that weird girl showed up too!" 

"Miura-san was there? Was she stalking you?" she teased, poking at his cheek.

"No, she wanted to take Reborn away because she thinks I'm rotten!" he ranted. "Plus, when she brought in Bianchi to "help" it ended up with my paper being destroyed! I had to recreate my sheet by looking at Yamamoto-kun's paper."

"Sounds like you had a rough night."

As the duo walked passed an alleyway, a strange figure started following them. Heavy footsteps followed the two students as they walked, but they soon took notice of them. Turning around, they saw someone dressed in protective gear, helmet, and had a hockey stick in their hand!

"HIEE!" squeaked Tsuna, backing away, before grabbing Naria's hand and began to run away.

"T-Tsuna slow down a bit!" shouted Naria as the brunet made a few quick turns trying to lose the person, who was not far behind them. 

"I can't! That thing keeps chasing us!" he screamed. "How long is this gonna take?!" 

The figure soon chased the two to the bridge overlooking the canal. That's where Tsuna tripped and fell on his face, letting go of Naria in the process. Luckily, the figure who was chasing them was out of breath too.

"T-Tsuna-san!" came a familiar voice. "Good morning."

"Ah, Miura-san!" can Naria's surprised reply as she recognized the voice. "What are you doing?"

"W-Wait, that's Haru?!" he stuttered. "H-How?!" 

Haru removed the helmet, revealing her tired face, "I was up all night, thinking."

"So you dress up like that when you don't get enough sleep?" he asked.

"I don't think that's the case Tsuna..." said Naria with a sweatdrop. "In any case, why are you chasing Tsuna, Miura-san?"

"Hahi! Call me Haru!" the girl exclaimed before becoming calm again. "Anyway, if Reborn-chan is really a hitman, and you're really going to become a Mafia boss, then you should be really strong!" 

Both Tsuna and Naria did not like where this was going. With that being said, Haru had put her helmet back on and challenged Tsuna. If he wins, she'll accept what Reborn told her and move on. Before Tsuna could even get a reply, Haru charged at him, her hockey stick raised, but she suddenly started stumbling around.

"You okay?" he asked, a bit concerned. 

"I-I'm fine!" was Haru's reply as she swung the hockey stick down where Tsuna last stood, luckily he moved out of the way.

Naria moved off to the side, wanting to avoid the conflict, but then noticed that Yamamoto and Gokudera were walking in their direction. Before she could even call out to the two, Haru mis-swung the hockey stick and nearly hit her instead of Tsuna. 

"W-W-Wait! AH!" screamed the brunet, trying to draw the girl away from his friend, which worked successfully. 

Turning to the sound of his voice, Haru ignored his pleas to stop and continued trying to whack him. 

"I'm not going to become a Mafia boss!" protested Tsuna as he ran away.

But Haru was taking his claims in the wrong direction.

"So you're just toying with Reborn-chan, then?!" she shrieked. 

"N-No that's not it!" Naria said, trying to back her best friend up as Tsuna dodged another swing at his head.

"Geez, don't move out of the way!" 

"But he has to if he doesn't want to get hit..." the blackette trailed off.

"Juudaime! Hime-sama! Move out of the way!" shouted Gokudera as he and Yamamoto ran towards them. 

Confused, the two looked up and saw that Gokudera had thrown dynamite into the air....and they could go off at any minute!

Tsuna tried to warn Haru of the explosives in the air, but...

"You're underestimating me." she retorted. "I won't fall for such a trick!"

Tsuna moved out of the way, seeing as the dynamite were about to explode, dragging Naria with him. Haru was unfortunate enought to not heed Tsuna's warning and got hit with the expolsion.

"HAHI!" 

BOOM!

When the smoke cleared, all that was left of Haru was her helmet and hockey stick. Concerned, Naria ran over to the bridge's railing and saw Haru trying to keep herself afloat! Her heavy armor weighed her down, and she was close to drowning.

"Big problem here, Tsuna!" Naria said, running off the bridge and down to the pathways by the canal, trying to help Haru. 

Gokudera and Yamamoto managed to make it to the bridge where Tsuna was having an existential crisis since he can't swim. Fortunately...

"You save her." came the voice of a familiar infant. 

On the edge of the bridge stood Reborn, with Leon transformed into his gun form. 

BANG!

The hitman fired the Dying Will Bullet and struck Tsuna in the forehead. Not long after that, his clothes were ripped off, except his boxers, and an orange flame bursts to life on his forehead. 

"REBORN! I'll save Haru like my life depends on it!"

Reborn then prepared two more bullets, the Screw Shot, and aimed them at Tsuna's ankles. Once they hit, Tsuna's ankles began to rotate at a very rapid pace. Once he hit the water, Tsuna swam fast and saved Haru, managing to make it onto the shore before the Dying Will Bullet's effect ended. Gokudera and Yamamoto ran down to help Haru and Tsuna dry off, with Yamamoto handing them a towel. Naria had a spare uniform for Tsuna, since she had a feeling that Reborn was going to use those bullets often. 

"Hope you've learned your lesson and stop stalking the Boss." scolded Gokudera. 

"Girls shouldn't be waving something like that." added Yamamoto. 

"Guys stop, she learned her lesson and then some." Naria said, using the towel to help Haru dry off after giving Tsuna a spare uniform.

Then, somehow, Kyoko and Hana arrived from the road above the canal pathway and saw the five by the bridge. The two girls walked down to get a closer look at what was happening, and Tsuna being the love-struck boy that he is, stuttered at the sight of Kyoko. 

Though that was cut short as Haru began chasing him, yelling how he was cool and how she wants Tsuna to hold her tight, which made Naria burst out laughing, Yamamoto quickly joining her. 

And on the bridge above them, was Hibari, Kyoya, looking down at the group of students.

"Crowds are such a pain."

At the sight of his student's growing family, Reborn gave one last smirk.

A/N: OH SWEET NAGA THIS TOOK A WHILE!

So this chapter and the series in general was delayed for several reasons:

1. I had no way of watching KHR until I did some searching and found a site where I can watch it. 

2. I had to rework some of the chapters and Naria's personality. 

3. Hiatus

But that's all done in the past. Now this story is back on track and I hope you guys enjoyed this chapter.
