Tsuki was chatting to her eight year old cousin, Stella, in the main family's garden. A maid walked up to them, "Tsuki-sama, your father would like to see you immediately," she turned around and walked away from the two girls.

Stella and Tsuki looked at each other. Stella mumbled while playing with an ant, "what do you think he wants?"

"I'm not sure," Tsuki whispered back and stood up. Kurai and she walked tensed to her father's office of the main house. When Tsuki made it outside the room she kneeled on the tatami and slid open the shoji.

The head of the family looked up from his paperwork, "enter."

"Hai," Tsuki whispered and walked in to sit in front of him. It wasn't that she was scared of her father that she was whispering; she was just always like this. She noticed he was holding a very decorative box.

He looked up at her, "Tsuki, you have been chosen as Vongola Decimo's Moon Guardian. You are at the age and skill now that I can trust you with this task." Her father opened the box in his hands. Inside were a grey box weapon and ring. "These are your weapons provided to you. The Moon fights independently and therefore has something different from the rest of their allies. In your case instead of obtaining Vongola Gear like the other Vongola Guardians and their boss, you will just have a Vongola ring and Box. Though, this is not to your disadvantage as it will be as equally strong if you can master it. You have been given one month to learn how to use this new weapon. When your time is up, you will meet and serve them as a guardian. Now go and preserve the family's honor. I have faith in you my child."

Tsuki's eyes widened as she stood up and was given the box by her father. She slowly nodded her head and walked out of the room. 'I need to start immediately,' she thought as she walked to the outdoor training grounds. Just before she reached her destination, Stella ran up to her happily and blocked her path. "Tsu! Tsu! What did he want?" Stella beamed like always. Tsuki was almost a complete opposite of Stella personality wise but she always had the patience for her cousin. The two were always together and Tsuki would do anything for Stella, even give her own life, as she considered her a sister over a cousin. She vowed to always protect her cousin after Stella was already hurt before when Tsuki made a mistake.

"I'm now the Vongola Moon Guardian," Tsuki told her. "I have a month to learn to use my new weapon, then I leave."

Stella's face lit up. "Wow Tsu! I knew you were amazing! I wanna be just like you when I get older," she tilted her head and pulled a huge smile.

"Thanks Stel, I'll try my hardest to fulfill my duty and always protect you. I promise." Tsuki pulled a small smile, kneeled in front of the short girl and ruffled her hair. "Now I must go and train myself," Tsuki immediately turned serious and walked outside.

"Tsu can I watch you?" Stella called from behind her.

Tsuki turned back around, "do you have nothing else to do around the house?"

"No…" Stella looked away.

Tsuki just giggled, "you must be the only person I can't be stubborn and reserved to. Yes, you can watch me."

Stella grinned and sat on the grass by the door to get a good view of her older cousin.

Tsuki's POV:

I looked at the box I was given by father. It had a Vongola crest on top. Wow, I'm actually going to be the next Moon guardian. I can't believe I was given such an honor… I opened the lid and saw the box weapon and ring I was previously shown. The ring had a large, grey, diamond shaped stone with an engraved moon on the top. I put the ring on my finger.

I remember in one of my lessons they taught us how to light a ring with flames but I've never done it before. You must have a strong resolve. My resolve… My resolve is to protect Stella from any more danger and to fulfill father's wishes. The ring didn't light. "Hm." I closed my eyes tried again and this time the ring lit a grey flame.

"Tsu, you lit it! You're so cool!" I heard Stella shout. I knew I lit the ring but now for my box. It was also grey with a Vongola crest. I inserted the flames into the box and a scythe shot out. The Moon Scythe.."Tsu! Kurai's glowing! Wait! Oh no! TSU HE'S ON FIRE!"

I immediately looked up at him. Kurai was smothered in Moon Flames. "Stel it's okay. Those are Moon Flames. I think this is because of my box," I whispered as the flames disappeared and Kurai walked towards me.

So I have a Vongola Ring and Box. I know how to light my ring and open the box. Inside is a Scythe and Kurai seems to also be affected. I have one month to learn my new skills and then I leave to meet my new boss. 'Well, well, well. Look what we have here,' I heard from behind me and abruptly turned around.


Two days before the month ends.

Tsuna's House:

"DAME-TSUNA GET UP!" Reborn kicked Tsuna out of his bed.

"HII! REBORN! Why did you do that?" Tsuna shouted back at his tutor.

Reborn's expression grew serious, "there's something very important I have to tell you so pay attention." Tsuna slowly sat up and looked at him. "You will meet your new guardian in two days."

Tsuna's eyes widened, "a new guardian? But I thought there were only seven flames… HAS SOMETHING HAPPENED SOMEONE!?"

"They're all fine but there is actually secretly an eighth flame. It's the Moon Flame. Their existence is always kept a secret and if someone says anything without permission, they are killed."

"HIII! This sounds dangerous! But is that why we've never heard about them before even with Primo's family?"

"Precisely, he had one but again it was a secret. Bearers of the Moon Flame come from a 'clan' Japanese family. They're name is Uchu. All their children are brought up learning to serve the mafia with their flame. This is enough talk for now but in two days you and your guardians will meet her in your house."

"Why my house and... A GIRL!?"

"Well we can't explain things in the open... And yes, her name is Uchu Tsuki. Make sure everyone is here in two days but don't say a word to them about why," with that Reborn exited Tsuna's room to breakfast.

Meanwhile:

Tsuki kneeled and breathed heavily. She whispered, "it has.. to be… perfect."

Stella's pink, frilly dress swayed in the wind as she cheered Tsuki on, "You can do it Tsu!"

Tsuki stood up and tried again, stubbornness showed in her eyes, as she knew she was not going to give up. Her time was running out but she was so close. 'Hm, if you really wish to be accepted as the Moon Guardian and become stronger you better hurry up.' A voice whispered to her.


Two days later:

Tsuki walked in the room next to Reborn, "hello, my name is Uchu Tsuki and I'm Decimo's new Vongola Moon guardian," she whispered to everyone.

CHAPTER END


It's only been a few hours since I posted her profile, but this just hit me and before I knew it, I finished the chapter. So hmm I wonder what happened to Stella in the past and who that person was when Tsuki was training. :)
