(Warning: This is not an AU! It's basically another storyline that is happening simultaneously with the canon, which seeps over and effects things occasionally. There are some major changes, but they are eventual and happen quite a bit later on. My intention isn't to rewrite the canon, merely to expand upon what is there and realistically add a character that wasn't there initially.)

The Girl That Talked To Herself

When Nana had found out she would be having twins she was ecstatic. Even more so when she heard that one of them would be a girl. As happy as Nana would have been with a boy she always secretly wished for a girl. However, she ended up getting both. No one could be luckier, she told herself. No one.

Iemitsu, her husband, doted on her from the moment he found out about their daughter. Not that he wasn't before, but it was almost as if his protectiveness grew ten fold. Nana figured secretly, he was hoping for a girl as well.

Now though, standing there holding his son for the first time, she could tell Iemitsu couldn't be prouder of their son. Through her sweat plastered bangs, Nana could make out tufts of chestnut hair already springing to life on the boy's head. Now that he was clean and no longer screaming, she wanted nothing more than to hold him tight and never let go.

Instead, another child was already occupying the woman's arms. Their daughter. Nana could see it now, they both looked just like their father. Maybe it was a little too early to tell, but she could already see their tiny features picking up the Italian in her husband's blood. In fact they looked closer to his heritage than even Iemitsu did.

Little did Nana know, there was someone else in that room that the children had an even more likeness to. An ancestor from years long past. The ghost of a man referred to as Primo in his time.

The unseen specter regarded the twins with curious orbs of honey, inspecting them close as if they were alien creatures. First the boy, as his flame was stronger than the spirit had ever encountered before outside of himself. Then the girl.

What he didn't expect however, was a pair of identical eyes glancing directly back up at him.

Several Years Later

"Tsuna-kun!" Nana called from the downstairs of their humble, two story home. "Have you seen your sister anywhere?" Tsuna, whom was in the middle of playing with the toys his Daddy had bought him the day before, didn't know per se, but he could guess.

"Backyard!" Tsuna called back through the open bedroom door, his voice slightly mangled by the recent loss of one of his two front teeth. Nana nodded to herself, she should have known.

Setsuna always spent her time out there.

The young four year old in question was currently sitting on the patio, chatting with a little boy. Both of them had the same wild blonde hair, and eyes that looked like two pairs of giant topaz.

"So how is your brother doing?" the boy asked. "I worry about him sometimes."

Setsuna pouted at the mention of him. "You always ask about, Nii-chan."

"That's because I know everyone else is fine... He seems a little too much like... " he trailed off, gazing into the distance at the setting sun. Setsuna frown slightly, following his line of vision. Every once in awhile Giotto would get like this. Where the two would be talking normally then all of a sudden he would get all sad.

"Well," Setsuna placed a tiny hand over one of his. "Tsuna-nii is good. Daddy got him some toys yesterday to cheer him up after a dog barked at him."

At that Giotto chuckled, his high pitched voice sounding like clear bells tinkling in the wind. "That's why I worry. Your brother scares way too easily. A Mafia Boss should be strong."

"Mafia Boss?" Setsuna quirked a thin eyebrow.

Giotto only grinned wistfully at her. "He may never have to be one... but I just have this feeling. Tsuna-kun looks way too much like me for it to be coincidence..."

Setsuna hummed in agreement. "You do look a lot like, Nii-chan."

"Sorry," Giotto apologized after a moment, remembering just who he was talking to. "You must be bored with this old man's ramblings."

"You're not an old man," Setsuna giggled, her golden hair bouncing with every laugh that shook her tiny frame. Giotto couldn't help smiling back at her. Setsuna was so innocent right now - she had no clue of the hardships she'd have to face as not only his descendant but a Medium at that.

"Setsu-chan," Nana said as she slid open the back door to the house. "Who are you talking to?"

"Giotto," Setsuna replied quickly, a grin still wide on her face.

"That imaginary friend again?" Nana shook her head in quiet bemusement. No matter where they went, Setsuna would always strike up a conversation with thin air. Even just walking down the street, Setsuna would run off, saying she found a friend to talk to. At times, it was quite unnerving, and as much as Nana wanted to write it off as simple childhood imagination she couldn't deny her growing unease over the subject. "Well, it's time for dinner, so go wash up."

Setsuna hopped up from her spot at the end of the patio, offering a hand to Giotto which he hesitantly accepted. "Can he come to dinner too?" the small blonde asked her mother eagerly.

Another sad smile crossed Giotto's features. "I should probably go back home. I can't stay long as it is."

Setsuna pursed her lips. "Come back soon?"

"You bet."

Then the little boy waved before disappearing in the wind. Setsuna waved back, already missing the boy she had gotten to know in the past year. Apparently no one else could see him, but she could. Despite how intermittent his stays were, Giotto was Setsuna's best friend.

-Ƹ̵̡Ӝ̵̨̄Ʒ-

Setsuna soon found that all ghosts weren't as nice as Giotto though.

When most spirits found out that she could see them they would demand something from her. Some wanted her to tell their secrets. Others simply wanted her to say their goodbyes. There were even a few extremists that demanded she get revenge for them.

As much as she wished she could help all of them, Setsuna couldn't deny that they terrified her. Especially the ones that didn't know how to hide the injuries that had caused their deaths. As a child the apparitions hadn't bothered her much since she didn't realize just what they were though.

By the time she was in her first year of middle school however she was already tired of it all. Tired of having to ignore ghosts so they wouldn't bother her. Tired of people staring at her when a ghost did feel so inclined to pester her and she would have to tell them to go away. Tired of feeling insane for being able to see things that other people couldn't

Everyone thought she was crazy - even her twin brother Tsuna. Sure, he wasn't mean about it or anything. But he could tell when she got that look in her eyes that she saw something that he didn't. Though, he attributed it more to his sister being weird than anything else.

Because of this however they weren't exactly the closest. That wasn't to say Setsuna didn't love her brother, because she would do anything for him, but there was always this impenetrable wall between them. Like no matter how hard they tried they were simply unable to reach the other.

So, when a spirit decided to randomly pop up in the middle of her Math class Setsuna wasn't particularly thrilled.

"Help... Me..." the man groaned. There were rope marks on his neck, and his head was lolling sickeningly to the side. Setsuna tried her best to avert her eyes, but he just kept moaning and shifting closer.

How stereotypical.Setsuna thought with a sigh. This was obviously one of the more freshly dead spirits. When they've been around longer they can hide the wounds that had killed them, and start to resemble their past selves more. This man however still thought he was alive.

"You... Can... See... Me... Right?" the ghost demanded, his hands firmly planted on the edge of her desk. "Please?"

Unable to take it anymore, Setsuna threw a thin hand into the air. "Can I be excused please?"

The whole class instantly bubbled to life.

"Here we go again," Setsuna heard a classmate grumble.

"Why do we have to have this freak in our class?" asked another.

There were similar complaints all throughout the room. Setsuna tightly closed her eyes, partly to block out the ghost staring intently at her and partly to contain the white hot anger boiling deep inside ready to burst.

When her teacher finally gave her leave to go, she heaved a sigh of relief. Though it was short lived once she noticed the ghost had followed her into the hallway.

"Help... Me..."

Setsuna irritably turned on a heel to face him. "You're dead, okay? So please just leave me alone."

The man's eyes widened with the realization. "I'm... Dead?" Then a bright light engulfed him and the manifestation of his body shattered, revealing a more normal version of the man he used to be.

"Better?" she asked delicately, giving him a small encouraging smile.

A grin took over his features as well. "Thank you... I think I can rest easy now."

Setsuna scratched at her neck sheepishly as he finally disappeared. Those ghosts were always the easiest to deal with. They were problematic regardless, but all they required was simply telling them what they were. Easy, but still irritating.

With a sigh, Setsuna ran a hand through the length of her long, blonde hair.

Now that she was so worked up there was no point in going back to class.

-Ƹ̵̡Ӝ̵̨̄Ʒ-

When Setsuna finally made it home she was surprised to find her brother already there. With a light knock on his bedroom door, she peeked her head inside, only to find him hovered over a manga... like always.

"Skip out early too?" Setsuna asked with a chuckle.

Tsuna sighed, flopping over onto his back. "Yeah, got stuck cleaning after P.E. again and didn't feel like staying."

"I know the feeling," Setsuna leaned into the door frame thoughtfully, crossing her arms over her chest.

Tsuna grimaced slightly at his sister.

Sure, everyone at school walked all over him but he kind of deserved it for being so useless. Setsuna wasn't nearly as bad as he was, but they bullied her just as much, if not more so. They were known around the school as the Dame-Twins. Though she was known more specifically as the girl that talked to herself.

As much as Tsuna wanted to stick up for his sister, what could he do for her? What they said about her wasn't wrong. Ever since he could remember Setsuna would occasionally space out and begin having conversations with thin air. For awhile he thought she just had an over active imagination - hell, he still did - but after a few months in therapy as a child it was deemed she was simply doing it for attention.

Tsuna couldn't quite understand why she would even remotely want the kind of attention they got, but ultimately it didn't matter. Regardless of her quirks, to him she was just Setsuna, his sister. Albeit his weird sister. But his sister nonetheless.

"Tsunayoshi!" Nana shouted at the bottom of the stairs, pulling both of her children from their thoughts. "I got a call from the school. You cut out during the middle of class again?" Nana was ready to bulldoze through the door when she caught her daughter already occupying the space. "Oh, hey, Setsu-chan!"

Nana pulled Setsuna into a quick embrace, causing Tsuna to scoff. "Why when I cut school you're ready to tear my head off but when she does it you hug her?"

"You cut too, Setsu-chan?" Nana asked suddenly, releasing her daughter.

Traitor. Setsuna sent Tsuna a look that said as much before ducking through the open door. Thankfully, Nana didn't chase after her and she retreated safely to her own room.

"Sorry, but you're on your own this time, Nii-chan," Setsuna apologized as she listened to the yelling through the wall. Their mom was really laying into him this time. After a few minutes however, the argument shifted and Setsuna could hear the stomping of feet down the stairs.

Curious, yet still wanting to avoid persecution, Setsuna hesitantly ventured into the hallway.

"I refuse to have a Home Tutor, okay?!" Tsuna exclaimed, almost shrilly. "I'm not good at anything I do anyway!"

"Ciaossu!" a high pitched voice squeaked above the commotion. Not recognizing the voice, Setsuna risked creeping down the stairs to figure out just what was going on.

The moment she reached the bottom of the staircase though, her and Reborn had fairly differing reactions of the other respectively.

She is the spit and image of Primo.

And,

Why the hell is there a ghost chained to the back of that baby?!
