She smiled indulgently at the little dark-haired girl beside her who stood on her seat to see if anyone she knew was on the plane, her brown eyes gleaming with excitement. The little child giggled when her father's arms came out from the row behind her and wrapped around her. They had been forced to sit apart due to lack of seating.

He picked her up over the seat and held her carefully. The woman smiled the entire time even as she held her sleeping son ever closer to her chest.

I suppose most people would assume that this story is about the woman, but it isn't, this story is about the twin sister of the boy sleeping in her arms, who happens to be the giggling girl snuggled with her father.

Now I guess I will give you some names to fit the descriptions. The woman is Nana, The man, Iemitsu, the boy, Tsunayoshi, and his twin sister is Sawada Aemi.

She isn't all that strong or important yet, at the age of 7 she has no idea that her father is in the mafia, and that her and her brother are candidates for the position of Vongola Boss. She won't know for many more years. Specifically, she won't know until she's thirteen, when her father will take her away from her quiet home in Naminori to travel to Unexpected Italy.

She will however, be secretly trained by her father her whole life without her even knowing, him sneaking up on her and attack hugging her, signing her up for Karate, fencing, and Kendo training, Sparing with her every chance he got and having her work on meditation for concentration and determination.

When she does get to Italy, she will learn it all, and accept her role, knowing that she won't even be considered for Vongola boss unless all the others die before her. She will find out, when she's fifteen that the others have all died and her and her brother are the only options left, and she will tell them that she will never be Boss without her brother by her side.

She will return home with her father, and she will carry a ring. The ring that had always been prepared for a twin sibling to wear, because this was not the first time such a situation had arisen, the first Vongola boss also had a twin sister, but his had died shortly after the ring had been made. She isn't what Tsuna and their guardians expect either, Tsuna hasn't seen her for years, and she has never met the others, Aemi will wow them all.

~~~~Current Time~~~~

Yanking hard, I finally managed to free my bag from under the pile of suitcases. It really was just my luck that the plane I was on had to belly land and ended up dumping all of our stuff on the ground.

My father groaned from the ground behind me. "Aemi? You alright?" I spun on the spot before offering my father my hand to help him off the ground.

"Yes, I am fine, missions with the Varia quite often end with situations such as this" My voice came out muffled and tangled and I made a dull disgusted noise in the back of my throat, after two years of speaking only Italian, my ability to speak Japanese had become severely lacking.

My father sighed in relief before realizing what situation we were in. His awareness of reality came suddenly flooding back, he blinked and finally grabbed his bag before slinging it over his shoulder. I stuck my arm once again deep into the pile to rescue my carry on bag.

I sighed upon pulling it out, I could hear the tinkle of broken glass within. "So it seems my present for mom didn't survive, well, at least I have the metal one still" I too slung my duffel over my shoulder before scanning the familiar areas nearby, The airport was set upon one of the sole hills in the area and seeing my old home brought a smile to my face. I missed my twin brother desperately, two years could do that to someone.

"Let us go home Father" I said as I slung my arm around his neck "We have been gone for much too long of a time"

***At Tsuna's Home***

-Tsuna's POV-

Gokudera patted me on the back hard before turning away, His voice was muffled when he spoke "Sorry Juudaime, but my sister is there and you know what it's like when she's there…" He dropped his head in embarrassment and slunk away, depressed to have to leave.

"Maa maa, We'll be fine, right Tsuna?" Yamamoto said with a carefree grin on his face and I was glad for the reassurance, seeing my dad's stuff was freaking me out a little more then I would've liked to admit.

I walked in and saw Bianchi who then told me that Mom was getting food because Dad ate it all, and then I saw Lambo, I-pin and Fuuta, all incredibly drunk. I ran to the back of my house with Yamamoto trailing calmly behind me, after slamming open the door my jaw dropped in surprise and disgust.

"What is he-" I paused "Wait…? If dad is here then that means…" A sudden light bulb went off in my head. I ran even faster then before if possible to get to the bedroom beside mine which had stood empty for two years, and sure enough when I slammed open the door I saw exactly who I had hoped to see "Aemi-nee" I said softly before launching myself on her.

-Aemi's POV-

"Ugh… Imouto! (Younger brother) I have not even had a chance to finish unpacking yet!" I sighed but still, I wrapped my arms tightly around him and hugged him hard "I missed you Tsu-kun" He hugged me back.

"I missed you too Aemi-nee" Finally, after about a minute I pushed him away.

"So who is your friend?" I said as I sat on the edge of my bed and gestured for his black-haired friend to enter the room.

"Yamamoto Takeshi" The black-haired g- I mean, Takeshi-san said. "And you are?"

"It is a pleasure to meet you, I am Sawada Aemi, Tsunayoshi's elder twin sister" Takeshi-san rubbed his head nervously.

"Um.. If you're really his sister, then why have I never met you before?" I laughed in response to his question where as he blushed.

"I've been in Italy with my father for two years, and before that I went to a private school for physical training" His smile returned even though he was still bright red.

"Well it's nice to meet you, will you be going to school with us anytime soon?" He paused "Or are you going back to private school?" I bit my lip, I had a response but they didn't know about the half-Vongola rings battle yet, so I couldn't tell them.

"In a couple weeks" I answered vaguely. "I need to get settled back into my home first"

Tsuna smiled and got up from the floor where he sat and I stood as well. "I might walk Tsuna to school tomorrow anyways, so I'll see you then" I said as I quite obviously pushed the two of them from my room. I paused before slamming the door in their faces "Bye!"

I turned and slumped against the door "Thank god they're gone, I don't know how I would've explained had Tsuna seen the content of the bag I was unpacking" Pulling myself up again I returned to my bag to finish unpacking my weaponry. What with the whip, the sword, and the daggers, let alone the guns and rifles, Tsuna would've freaked.

I fingered the half-ring hanging on my necklace. I suppose, Tsuna doesn't need to know about any of this yet.
