Sawada Tsunayoshi, an average looking girl who had a basic school life that consisted of bullies, generally low grades and a failed love life. It was on that fated day she never knew would come and face her.

It happened when the clumsy 14-year-old was walking home from Namimori Middle, clutching her school bag and wondering what to do with the pile of homework her teachers had dumped on her desk.

Once the Sawada household came into view, Tsuna quickly slid the gate open, shutting it behind her with a small click. She rushed to the door, fishing out her keys and getting ready to insert one in the silver keyhole.

Just inches from unlocking the door, it suddenly swung open, revealing an infant wearing a suit and a chameleon placed on its fedora, seemingly waiting for Tsuna from inside the house.

"HIIIIEEE!," Tsuna shrieked as she toppled to the floor, startled from the abrupt action, before getting on to her feet and brushing back her long brown hair into place.

The strange guest stared intently at the girl with nonchalant midnight eyes. Tsuna squirmed uncomfortably at the gaze, avoiding eye contact and instead pretending to look interested in glancing at the wall on her left.

After an awkward silence, a reply coming from the baby broke it.

"Humph. Who knew the next Vongola boss would be a female. How unexpected."

Tsuna snapped her attention back to the baby. The appearance was adorable with the chubby cheeks, and it took some effort for the girl to suppress a girly squeal. But it wasn't the only reason that stopped her from doing so. The aura coming from the baby was... Unusual, in a way.

"Ciaossu."

She flinched, forgetting about her deep thoughts. "Umm... Wh-who are y-you?"

The infant smirked, sending chills upon Tsuna's spine. Was that a glint in its eyes?

"I am Reborn, a hitman belonging to the Vongola Family, the strongest Mafia Family in the world," the infant confirmed.

Tsuna's warm brown eyes widened in shock. Hitman? Family? Vongola? Mafia? What did all these words have to do with her? They all seemed so dangerous.

"You, Sawada Tsunayoshi, are a direct descendant of your great-great-great grandfather, who was the one that founded the Vongola. Therefore, you are the rightful heir to the Family by blood, despite your gender. I am here by orders of Vongola Nono to train you into becoming a suitable mafia boss," Reborn explained.

"Huh? B-but isn't th-there anyone else s-suitable for the j-job?," Tsuna stammered out, scared of what was to come in her future. If she ever had one in the first place.

The hitman's expression darkened, the tone in his child-like voice turning serious.

"No, there are no other candidates competing to become the next boss. Three of Vongola Nono's sons are already dead. You are the only one standing in this place. And your father has continued on as a boss of the Family's organization, CEDEF, so he doesn't count."

"Wh-what about m-my father?," Tsuna asked, confused.

He was part of the mafia? So that was why he rarely showed up in Namimori? She didn't know much about her dad, much less remembered what he looked like. Only photos allowed her to see him with her mother, Nana. As father and daughter, they looked nothing alike. So what was there to believe their relation to each other?

"From now on, I will be your home tutor until you become the boss, so you better be ready with the training I give you," Reborn replied, ignoring Tsuna's question.

The boss candidate shivered and blanched at the statement. She was less likely to expect surviving this 'training.'

"Does that mean... M-my mother h-hired you?"

The hitman smirked, his chameleon crawling down his arm to rest on his tiny hand. The creature soon materialized into a green gun.

"Of course. I planned all of this to happen from the beginning, just to take a good look at you. Tsuna."

A cold sweat trailed down the unfortunate girl's forehead. This baby was no longer cute, nor was it ever adorable. It was simply evil, like a malicious spirit had possessed him or something.

"Hiiie! Th-then where is my mother?," she cried out, frantically moving her head from side to side.

"She went out shopping, telling me she will come back to prepare dinner."

Reborn pointed the green gun at Tsuna, who was panicking and thinking of ways to escape this life or death situation. After all, she never planned on dying young. No. Not yet.

"Let's get started, shall we? Tsuna."

Hearing her name being said by a sadistic psycho baby was like demons announcing your death sentence.

This was all it took for the poor teen to scream her heart out, desperate for someone to spare her from harm and danger.

"HIIIIIIIIIEEEE! I DON'T WANT TO DIE JUST YET!"

The frenzy was going to occur for a long while in the Sawada household. This is how Tsuna's proclaimed sealed fate was known that afternoon.
