SweetCrispyCrunch: Okay this idea took a looong time to build. For my first fanfic I wanted to and to try really hard to make a good oc. So far as I'm building it I'm thinking Coda is going to one bada** female character.

Khr the plot and characters belongs to Amano who will not add any awesome moments to the very few female roles. *Cough Chrome *cough

Coda was made and formed by a friend and I. We both have pretty messed up minds, Coda is merely a huge chunk of you my dear…

Prologue: "One and only one mission is given"

"Coda you have one mission only." The small girl looked up at the dark shadowy figure the smoke of a cigar in his hand was burning her eyes she could barely see.

"My mission is to infiltrate the Vongola Familia."

"And how will you do that?" The man asked calmly.

"…I will become the ally." She said, it was recited to her many times before but hearing them come out of her own mouth sounded mellifluous and rather pleasing to the ear.

The dark figure did not respond nor comment on her answer he chuckled and petted her slightly on the head.

"Good girl."

Her eyes shot open. Coda sat up and realized the train was still moving. That was not a dream it was an exact memory drilled into her mind. Coda didn't sleep as much as she should, so when the sun went down she tended to replay the last instructions she was told by the agency. It had taken her five years to perfect her training and strategy, and now her mission is finally taken to action.

There was files to pinpoint the location of the next Vongola heir locked and secured by the ninth himself. But Coda didn't have to, like so many mindless assassins break into the mansion to obtain that. All she needed was a photo and she knew exactly where to go. It so happens when Coda was briefly walking past the boss of the CDEF organization's office she saw a certain photo plain as day on his desk. A family picture that included: the ninth, the CDEF boss, his wife, and a son. Her target was established that day. Sawada Tsunayoshi the grandson of Sawada Iemetsu was the next Vongola boss.

She leaned against the window of the train car staring at the mild reflection that displayed her face in front of the passing trees outside. Her teachers had told her multiple times that her face alone was a clear advantage. It displayed innocence. Her big doe pale blue eyes were bright and noticeable but not at all piercing. She had the appearance of a young girl but the mind of a killer. Not often those two combine but when they did well it was a bomb just waiting to blow up. That is why they named her Coda. She is the last resort and the big finale, of a beautifully organized composition in a grand orchestra. The dark figure the man with the cigar is the conductor. If he leaded her and the others to the right direction the plan will go smoothly before the tenth generation boss takes his position. The train pulled to a stop.

"Arrival Namimori station." The intercom announced. Coda stood up she was wearing rather casual clothes to make her inconspicuous in Italy but she will soon have to change that. Her target has to come to her she has to gain his full and complete trust in order to take him down.
