Nogitsune rises
I assume "Kitsumaru"'s "Kitsu" is taken from "狐", kitsune, which is "fox" in Japanese? Well, in any case, I would like to suggest more fitting name for your character; 姿変ココ, Shinaka Koko(姿変 basically meaning "shape change" and ココ coming from 狐子, which means "Fox Child" and where "子" is usual suffix used in female given names).
Chapter 1- Nightmares and Promises
Shinaka Koko tentatively stepped into the shower. The scalding hot water washing the grit and blood on her body wash down the drain. The worst of it was on her hands, the dry caked blood peeling off under the water. With a sob she slid down the glass wall of the shower, head hanging in her hands.
The worst thing was that most of the blood wasn't hers.
She sat in the shower as it turned icy cold, scrubbing until her skin was rubbed raw. Starting to shiver she turned the shower off and dried herself off, being careful of the gash that ran diagonally down her abdomen and puncture wound in her lower leg. She re-wrapped the wounds, and deeming the other wounds non-fatal she curled up in bed, hoping it would allow her some comfort from the horrors of the day.
All night she tossed and turned dreaming about what transpired, as even in her home where she felt the safest, the nightmares still reached her. Most where ones she has had before, but others were as fresh as her wounds.
In the first she was kneeling on wooden floorboards eating at a low table set before her. Her parents sat across from her, laughing as she got Miso soup all over her face. Their features were clear, her mother's purple eyes, so much like her own; her father's short white hair, that no matter how much he brushed it, it always stuck straight up, but beside the sound of laughter and the smile on their faces there was no animation. No movement of their mouth as they stared at her. No crinkles to her mother's eyes that occurred whenever she was happy. They were still like the pictures she had to remember them by.
She saw two Iwa shinobi stalk forward, melding seemingly from the shadows at the corners of the room. They snuck up behind her parents and before she could scream the two-shinobi placed their hands over her parents mouths before slitting their throats. As she hopped over the table to reach her parents, sending neatly placed bowls from dinner crashing to the floor the scene changed.
Next all she could see was brief flashes of black hair, rocks crushing half of a young teenage body. That only hours ago was sitting beside her, laughing with her as they recalled one of his most recent excuses for being late. She tried saving him, but was unable to. His body was crushed beyond repair. the only thing still showing the tiniest piece of life was the three spinning black tomoe set against a crimson background, as red as the blood beating out of the boys body. "OBITO!" she screamed out as she ran towards the falling rocks, only to be jerked back in a flash of silver.
Then the scene melded into another, set just a few hours ago. The screaming of the villages and countless shinobi as they were battered aside into steel and concrete, or impaled by claws and flying shrapnel and misfired jutsu. The crying of the children, as they met the same fate or saw their own parents murdered before them, far more violently then her own. The worse sound that chilled her to the bone, and called towards the beast inside of her was the blood curdling roar of the Kyuubi no Kitsune. Taller than all the buildings around it, taller than the Hokages' mountain itself.
She saw her hands as she smothered a child. The kid clawing at her hands, eyes wide and pleading her to let go. A large gash ran down his body. From the right shoulder to his left hip. She knew he wouldn't have survived, his organs had been shredded and his entrails spilled out of his stomach. If she hadn't done what she did he would have died a slow agonizing death. Her form of death was the lesser of the two evils that was killing him, but it still made her feel sick. She couldn't even protect a child, much less the people she grew up with.
When the child stopped struggling and his eyes lost the pain in them, she thought she saw forgiveness but it was gone a second later. Letting go of the child she lay him on the ground and closed his eyes, refusing to see the shocked and horrified faces of the people around her. Judging her for not letting a child die a long and painful death.
She looked up to see her surrogate father figure fighting against the beast, on top of his toad summon Gamabunta. She saw a the appearance of smoak as the toad vanished and the Yondaime's legacy falling to the ground. Moving as fast as she could she sprinted towards the falling body, muscles shifting beneath skin as she changed.
In her dream she wasn't fast enough and watched as the fragile body hit the ground, blood scattering beneath the tiny body.
She woke after that, sitting straight upright as a scream burst from her lungs, until her throat was hoarse. Feeling suddenly too hot underneath the sheets she ran to the bathroom and vomited into the toilet. She leaned down onto the floor, breathing slow, body shivering. She knew she had managed to catch the child before it hit the ground, but she couldn't get the thought out of her head. What if I failed? What if Naruto had died?
Thinking of the small boy; his ocean blue eyes and his grinning smile as he looked up at her bruised and bloody body, brought a small smile to her own lips. She had saved him. Saved the last part of the man who took her in after her own father died.
With renewed determination she got up off the tile floor, walked to the window and opening it she whispered into the wind: "I will protect your son Minato and Kushina. I swear by my blood I will protect Naruto."
The wind carried her message silently through the village, the trees and finally up towards the moon hanging in the night.
A/N Sorry for not updating for a while, I have been struggling with family drama while balancing uni, but I'll try to update more now. For the moment I'm updating previous chapters, adding more description and changing a few plot points.
As always R&R.
