In Niigata on 14 October 2xxx, born a pair of beautiful twins. A boy and a girl. Their parents are the Sawada couple, Sawada Iemitsu and Sawada Nana.

They named their babies with Sawada Ieyatsu for the blonde boy and Sawada Tsunayoshi for the brunette girl.

That day is the best day for the couple because since then they can finally be parents like what they always dreamt of...

~Timeskip~

It has been 6 years now...

Sawada Family is known as the happiest family in the whole village.

although the youngest twin that known as Tsuna grow up as a blind girl, they don't seems to bother that and even supported her as much as they could. Mostly Ieyatsu, the eldest twin who grown protective for his half...

They lived a wonderful life...

But sadly that didn't last long as an accident happened...

It happened on 14 October. Sawada was having a small party for their cheerful twins. Althought that they lived in a small cottage everyone in the whole village seems to attend, sharing happiness for the birthday for the two.

"Kyaaa! my Tsu-chan and Ie-kun is now 6 years old! I'm so happy!" Nana squealed while Iemitsu then added, "Hya! my beautiful twins~ Happy Birthday! Here, come to Papa!" The three of them then hugged the man while laughing happily almost forgetting that they have guests watching them with awe.

"Happy Birthday my dears... I wish you a happy life~" an old man said as he kissed the two on their forehead while they giggled.

"Happy birthday Ie-kun! Tsu-chan! Here, your present! I pick them by my self!" One of their friends said, and of course the twins accept it happily. of course not forget to say their thanks.

and so they continued with the party. Once they're free from the crowded people the twins finally have time for each other.

"Happy Birthday Tsu-chan, I wish everything that you wished for come true" Ieyatsu said with a grin.

Tsuna smiled back at her twin as she replied, "The same to tou, Aniki... Happy Birthday..." They then spended their time together on the outside staring at the sunny sky with Tsuna leaning on Ieyatsu's shoulder and Ieyatsu clinging his hand to hers.

No one dare to ruin this cute view and so they just let them be...

after some moments Tsuna suddenly stood up, startling Ieyatsu who started to get sleepy from the comfiness...

"What's wrong Tsu-chan?" Ieyatsu asked as he rubbed his eyes cutely.

"Aniki... someone is calling for help. She said she's in trouble..." Tsuna said in whisper as she pointed at one direction.

Ieyatsu narrowed his eyes to that direction but all that he can see is snow for miles and nothing more. "I don't see anything, Tsu-chan. and why are you whispering?" He asked. Tsuna just simply give hima a look that only him would understand.

"did sheasked you through your mind?" with that Tsuna nodded.

No one other than them two know about the gift that Tsuna has. She might lost her sight since a very young age with an unknown reason, but in return she has an ability to sense Yokai and Ghost. One time, Ieyatsu spotted her chatting with their anchestor, Giotto. And since then this secret became theirs only.

Tsuna said that Yokai are almost same with humans, they just lived in different realm that humans can't see. They had saved some of them from trouble thanks for Tsuna's ability. Ieyatsu had witness their kindness through what they did to Tsuna as return for the help. but of course he also aware that just like humans Yokai can be dangerous, and that they have to be careful for the evil one...

Ieyatsu glanced over his shoulder. Their parrents are bussy handling the guests. Seing this oportunity Ieyatsu grabbed Tsuna's hand, "come on..." he said.

"so which way is it?" Tsuna then pointed the way as Ieyatsu become her 'eyes' and guide her from obstacles.

all of the sudden it's snowing, and just a couple of minutes later it's gtting harder and harder. "Tsu-chan! I think a storm is coming! we should go back!" Ieyatsu shouted so his voice can be heard due the loud breeze.

"But she's right there! just a bit longer! she neeeds our help Aniki! we have to helped her!" Tsuna shouted back determinded.

Ieyatsu knows her. and she wouldn't bite her own tongue. She'll always go ahead to reach for what she wants. and so all that he can do is sighed, "Okay, but we'll get back as soon as we finish got it?"

"Un!" Tsuna smiled.

They then tighten their grip and getting closer at each other for warmth.

Tsuna is right, someone indeed is calling for help. However it's not a Yokai as Ieyatsu can see her too. or that's what they thought.

a long black haired young lady who sitted on the snow.

"Please little ones... help me. My feet is hurting and I can't walk my way home..." she pleaded.

Ieyatsu stared at her beautiful face...

Her eyes are sparkling blue, her lips is pink and her face is pale white. 'this beautiful lady must be freezing from being outside for too long just wearing a kimono. Poor lady'he thought. 'Good thing Tsuna insisted to get us here.'

However when he glanced his twins face, there's no gladness or even happiness on her face, instead it has a horror expression as she stared blankly at the lady.

"A-Aniki... we should get run... NOW!" Tsuna then dragged Ieyatsu with much force, shocking the boy while on the same time making him confused as well.

"What's wrong Tsu-chan?! why are you suddenly dragging me? There's a poor lady that asking for our help right there, shouldn't we help?!" Ieyatsu asked while keeps on running.

"Aniki, she's not a lady... She's a yokai. an evil one... She's Yuki-Onna!" Tsuna just finished talking when the said Yuki-onna suddenly appeared right in front of them, trying to get them with her pleading look.

"please... why wouldn't you help me?" she asked.

Ieyatsu pulled Tsuna to his back as he growled at the Yokai, "stay back you evil Yokai! you will never get anything from us!"

The beautiful Yokai just grinned... creppily. as it's spread widely passed her eyes.

"and what can you do? you just a weak human. but your life source would be perfect dinner for me. so why don't you just stay still until I finished." she said then laughed creepily. "I promise that this won't be hurt..." She then began to attack.

Ieyatsu jumped backward along with Tsuna just right in time before she can get them with her sharp teeth. but that's just a luck as Tsuna then got bitten...

"AAAAH!" She screamed as her life source is being sucked away from her.

Ieyatsu tried to freed her by kicking the Yokai. but he's not strong enough...

Bur suddenly something blinding hit the Yuki-onna, making her dropped Tsuna who's barely alive by now.

Ieyatsu hurriedly on her side, hugging her protectively as he cried her name. Just then another blinding light came before him, he can also heard the Yuki-onna's scream of pain afterwards.

'w-what's going on?'Ieyatsu questioned.

He then saw, before him there's so many Yokais in front of them, protecting them from the Yuki-onna.

"W-Who are you?" Ieyatsu asked in scare as he pulled Tsuna closer.

one of the Yokai smiled at him as he answered, "we're Yokais that you and your twin have helped in the past. and now we would like to return the favor..."

Those Yokai then attacked the Yuki-onna who got defeated easily remembering that she's out numbered big time.

Ieyatsu can only watched as they shooed her away.

Just then Tsuna grunted, snapping Ieyatsu's attention back to her.

"oh Tsuna... *sob* I'm sorry... I'm so sorry... *sob* I can't stopped her *sob*I'm not strong enough... I'm sorry" he said.

"I-It's not your fault Aniki... I-I'm the one who dragged y-you here... I-I'm s-so sorry..." Tsuna said between her sharp breath. They both know that it's only matter of time before Tsuna's time's up. She can't survive for long after that attack and so Ieyatsu cried much harder while hugging her tightly not wanting her to go...

The Yokai is touched at the view, they can't stand to see this sad momment. and so they all agreed to help them.

the one who act as their leader then speak, "Dear boy, Tsuna is our friend. She had helped us so many times in the past. and so were you. So if you would, please let us helped her..."

Ieyatsu shooked his head as he stepped back, "what are you going to do with her?!"

The yokai smiled, "she can no longer live as human, but she'll survive if we changed her into our kind, Yokais. but if we do,you might not see her ever again like how you can't see us before today. So, what's your choise?" he asked.

Ieyatsu stared at his sister, her face started to pale, her breath is getting short and she's freezing. He can't let her die like this. and so he decided to go home by himself while handing her beloved twin to the hand of the Yokai...
