Tsuki no Shugoshin

Summary: Who is that pervert in his boxer? Is that thing on the baby's hand a gun! Namimori sure is an interesting town. Pft, like I care….80xOc

AN: this is like a retell story of KHR with my OC, Hoshina Natsuki, in which the name Natsuki literally mean Summer Tree. Notes: First attempt as retelling a manga or anime in words. Title means Moon Guardian. I know people out there already used the idea of Moon Guardian. But the meaning of this "Moon" will be unique. Guardian in Romaji could be spelled many ways but I'm not really sure how to spell the right one so I used Shugoshin instead.

P.S. this is not beta-read

Chapter 1

Legend had it that the moon took shape of a woman to guide those who were lost in the darkness. The ever beautiful Moon that glitters brightly in the night sky is the symbol for kindness and beauty.

"Pft… Yeah right," A teenager mumbled as she stared at her laptop boringly. She was dressed in Namimori High School uniform. Her silky black hair was tied back into a high ponytail. Rimless glasses adorned her face. Behind those pieces of glass is a pair of brown eyes. She stared boringly at her wrist watch. It was her first day of school and she doesn't want to be late. She quickly shut down her laptop and grabbed her school bag. She slipped on her shoes and shouted, "Ittekimasu~"

"Ah, Natsuki-chan, your bento," a woman voice hollered.

"Oops, almost forget. Thanks mom! Ittekimasu!" she grabbed her lunchbox and walked out again.

"Itterrashai~" Her mom responded.

On her walk to school, she was enjoying the stillness of the street when suddenly a noise of a gun being fire pierced the silent.

"REBORN~!"

She heard someone shouted and turned around. A half-naked brunette charged passed her while shouting, "I WILL CONFESS TO KYOKO WITH MY DYING WILL!"

"Pft… no one care you hentai!" Natsuki muttered.

The rest of the walk was not so peaceful. The image of the boxer imprinted into her innocent mind. She was so focus in trying to get rid of that horrifying image that she reached the school yard without even knowing it.

A vein popped on her forehead as she saw that hentai person. 'Doesn't he know that public nudity is a crime?' She thought.

Then she saw a baby dressed in a suit and wore a hat with a pet chameleon. She was surprised. She didn't know that baby can talk?

Curious, she decided to approach the baby.

"Ne, are you really a baby?" She asked suspiciously to the baby.

"Ciaossu~," the baby greeted, "Dame-Tsuna, your late," He said harshly to the brunette.

"Ah~, I'm late," The boy yelled and grabbed the spare clothes from the baby hand and dashed into the school.

"I'm Reborn, a Hitman," he introduced himself darkly.

"Pft… hey Reborn, I'm Hoshina Natsuki, and nice joke," she smiled.

"It's not a joke," he said and pulled out his gun and pointed it at her.

"Tche… You are too serious. Bye-bye Reborn!" she rolled her eyes, showing no reaction toward the gun and dashed into the school.

"Interesting, perhaps she'll be Tsuna first family member," Reborn smiled to himself.

During the first half of the school day, all Natsuki heard was hentai this and hentai that. Seem like the person that zoomed passed her and left this lovely image into her poor mind, was the hentai and his name is Sawada Tsunayoshi. What even worse, Mochida is challenging him in a kendo match for dishonoring Kyoko.

"Pft…this will be interesting," she grinned and make her way up on the roof. She was enjoying her lunch when she suddenly heard a shout of frustration.

She turned around and off to the far corner of the roof was Tsunayoshi. A vein popped in her head and she decided to ignore him and continued eating her lunch. His shouts of frustration become more and more annoying until she finally exploded and marched toward Tsunayoshi.

"Sawada Tsunayoshi, if you scream again I swear I'll punch you, understand?" She hissed at him.

"Ieeep, U-Understood!" He stuttered in fear.

"Good, now let's us see what is the problem?" she said and took a seat next to Tsuna, "I'm Hoshina Natsuki, by the way,"

"Sawada Tsunayoshi," he said.

"Pft… everyone know you as a hentai or Dame-Tsuna, so no need to introduce," She said rudely. She had learned his name through all the rumors, the infamous Dame-Tsuna.

"Ah, ok, well you see…"Tsuna started explaining his encounter with Mochida after his confession.

"Baka!" Natsuki said and lightly wacked Tsuna in the head with a paper fan that appear out of no where. "Why bother to getting frustrated over something so insignificant. Beside, you are the one who started all of this. So you better go fix it," She scolded.

"B-But I don't know Kendo," Tsuna whined.

"Pft… just because you don't know how doesn't mean you can't win. Beside, I'm sure they are going to cheat anyway," Natsuki said, giving him her trademark 'noise'.

"You mean for me to cheat?" Tsuna eyes widened in shocked.

"Heck no, Sawada-san! I'll give you tips regarding of Mochida-senpai," She then smirked evilly.

"H-how?" Tsuna asked

"Oh, just watch," She said and took out her Laptop that she secretly brought with her to school. Of course, no one noticed because she concealed it carefully. She doesn't trust her mom to leave her Laptop at home. Just like the saying, like daughter like mom, her mom constantly trying to hack into her daughter laptop and invaded her privacy.

She turned on her laptop and typed in the password. A screen popped up and she click on one of the application. A window popped up and she started entering row and rows of numbers. Tsuna looked at her confusedly until a picture of Mochida show up. 'She freaking hacked into other people private life!' Tsuna gasped in shocked.

"Mochida, captain of a kendo club, age 16, Date of Birth: March 13, huh… interesting. He just started kendo 2 years ago. This guy is a weakling, I'm sure you can beat him," Natsuki smirked and closed her laptop. "I wish you best of luck, Tsuna"

"Eh… I thought you were going to help me?" Tsuna whined.

"Pft… There is no such thing as a free lunch in this universe. You must first earn it. 'Hint' his head will be exposing. That's it. Have fun," She smiled wickedly and walked down the stair to her classroom, 1-A.

The school bell ring, indicating that the school day has finally come to an end. Mochida and his friends were laughing maniacally saying that Tsuna chicken out.

"Nah, he'll come," Natsuki told them.

"How did you know, Hoshina?" One of the senpai asked.

"'Cause he is over there?" Natsuki said and pointed at the door.

Everyone turned around and saw Tsuna holding the wooden sword.

"Yosh, Dame-Tsuna, Ganbatte!" Natsuki smirked when Tsuna approach the group.

Everything happened so fast. At first Mochida was whacking Tsuna mercilessly with his bamboo sword. Then suddenly, Bang! Tsuna was down only to rise up again half-naked!

"REBORN, I WILL DEFEAT YOU WITH MY DYING WILL!" He shouted.

Natsuki noticed the baby out of the corner of her eyes. 'Hm~ so he is the cause,' she thought, 'how interesting,'

Tsuna was mercilessly plucking Mochida hairs. 'Oh~ so he decided to take my hint,'

Thus Tsuna won the tournament. Kyoko suddenly approached Tsuna and congratulate him. It turned out that she thought the confession was a joke. She then asked to call Tsuna by his first name. 'Woops, I forgot to ask his permission for the use of first name, oh well,'

While Kyoko was speaking to Tsuna, Natsuki silently slipped out of the gym. However, she was confronted by Reborn.

"Hi there, Reborn," She greeted.

"That was quite skillful of you to hack into the school website," Reborn compliment.

"Thanks, could said the same to you. When you said you are a hitman you are not joking are you?" Natsuki said.

"Oh? You noticed the shot?"

"Precisely,"

"Want to join the Mafia?" Reborn asked and pointed the gun at her.

"Do I have any other choices?" Natsuki chuckled nervously.

"Nope…" Reborn said and prepared to pull the trigger.

"Alright, Alright! Who family am I going to join?" Natsuki shouted desperately.

"Tsuna's, the Vongola Family," Reborn concluded and the gun transformed back into a chameleon.
