The Twin Sister( Shikamaru X Oc )

Prologue

The day when the Nine tailed beast attacked the The Hidden Leaf. The fourth Hokage , Minato and his wife Kushina were restraining the beast. Kushina carried both their twins in her arms , while Minato was preparing the sealing.

They lay both their children in the center and it was now time to seal the beast.
The younger twin (aka Naruto) was sleeping , while the older twin (You) was wide awake. Watching the events unfolding Infront of her.

The beast Kurama has been creating chaos and killing many shinobi's . Kushina was restraining it using her chains to stop it from  moving any further.

It suddenly tried to stab the twins using one of its tails. But both Minato and Kushina shielded them.

Blood was scattered. 

The older twin was still watching and looked eyes with Kurama...the beast stoped it's movement and watched the infant infront of it.

Minato used the opportunity and made the hand signs for the sealing.

Sealing the beast inside the younger twin...
 

  Alongside the conscious of their older child.

After the sealing, Minato fell to the floor alongside Kushina and sadly passed away.

The others alongside the Third Hokage arrived for aid ...but they were too late...seeing the fourth Hokage lifeless in the ground and a dying Kushina...He ran towards them and sat beside Kushina.

" Lord Third---" Kushina spoke like a whisper.

Lord Third was in tears seeing Kushina's dying state.

" My children..." Hearing this, Lord Third looked at his surroundings and heard a crying baby...

" Jeff!!! Take the children to the hospital!" Yelled the Hokage.

The twins were taken to the hospital leaving their dying mother with the Hokage.

" Minato and I decided to name our twins...Naruto and Y/n ...*heavy breathing*...we got it from Master Jiraiya's make out book.....Y/N... ,she is part of the  SEAL.... please protect here..." A tear fell from her eyes and with  her last breath , she smiled and passed away.

The Hokage was crying while he held Kushina's cold body and wept " Don't worry..Minato...Kushina, I'll take care of the twins."

A funeral was held for all the dead Shinobis that died in the battle.

Lord Third visited the twins in the hospital.

He saw the seal mark on Naruto and looked away...

LORD THIRD'S POV:

I left the room that Naruto was in and walked towards Y/n's room... It was off limits from the outsiders...when I entered the room, there was a strong pressure keeping me away from the child...It seems that a huge amount of chakra is surrounding her and is protecting her from danger...Chains were surrounding her like a barrier keeping others away.

I slowly walked towards it and it let me pass and carry her...the chains then surrounded us and I walked away from the hospital towards the Hokage's building.  ( I don't know what it called so let's just stick with it)
   
I already prepared a room for the unconscious child...

I made sure it was one of the heavily guarded place in the Hidden Leaf...I've assigned two skilled Anbu's to guard the room and made sure they keep distance for their safety.

It seemed that she was in a coma...

I took care of her...making sure she is well kept...Only a few know of her existence...

She attack others that's not me...
Not letting others coming near her...her chakra was active even when she is in a coma...

The only thing I know is that she cares for Naruto a lot...

I tried putting Naruto beside her and the chains surrounding her became stronger..protecting Naruto from harm...a sister's instinct to protect her sibling is seen in her.

I chuckled at this behaviour.

I've been taking care of her for years and keeping her safe.
Jiraiya often visits her and surprisingly she didn't attacked him.
She recognizes him as someone she must protect.

I feel guilty not telling Naruto about her...
I also noticed that everytime Naruto gets picked on other children and hurt him , resulting in bruises...
The chains surrounding her seems to react to this and getting out of control, destroying some parts of  the room...it was ANGER...

It is a possibility that she knows what's happening around Naruto...
But she stops when Naruto won't let it get to him and yelling that he would become Hokage.

She would smile when this happen and the chains would be calmer

When Naruto is lonely ...her chains change color and I would see tears in her closed eyes.

She felt his loneliness... It seems that she wanted to be around him.

I pity these children...
