Kana Uchiha is born in the middle of a battlefield with her mother fighting until she can no longer for the good of her village. She is born not knowing that red would be the most usual color of her life, not knowing that she had no choice but to become yet another child soldier.
She is born with the expectation of everyone dictating that she would be a warrior, an assassin, and more weapon than human. So she is molded and forged before she can even speak complex sentences.
Kana Uchiha is one year old when she starts walking; two when they start teaching how to form hand seals and how to hold a weapon; three years when chakra exercises begin and literacy begins; four years when she enters the Ninja Academy.
She is five years old when she sees what happens to the Uchiha children who go to the battlefield and manage to survive - and she is scolded for crying because Amane is crippled but alive and it's more than most can do.
Kana Uchiha is six years old when she is considered proficient enough to fight in the Konoha and Iwa conflict. At age seven she loses Ikuto-Kun and Amu-chan, and her eyes burn with hatred and sadness that consumes everything around her. Her sensei – almost dead, but not yet – points her eyes and holds her hand, letting her know that she has the Sharingan.
The war was over and she somehow survives - and continues to survive, through the ranks of chunin, jonin, and finally gets into the Uchiha police force, doing her duty and meeting almost every expectation that an Uchiha, a citizen of Konoha, a shinobi should fulfill.
Almost every expectation, in fact, because even with all the pain, war, tears, corruption, and cruelty her eyes have ever seen and her hands have committed...
She is still more human than a weapon and her heart loves much more than it should. She loves the people, she loves her team, she loves her village, she loves her clan, and she loves life with a burning passion.
Kana Uchiha is fifteen years old when Itachi Uchiha, the prodigy, has a psychotic break and starts massacring the entire clan. She runs and runs and runs, holding her neighbor's crying baby, grabbing an equally desperate cousin with his little brother in his arms, and then... then there's nowhere else to run.
She fought but it was not enough – not against his refined training and sheer genius.
She doesn't beg for mercy. She's an Uchiha and Uchihas don't beg.
Itachi Uchiha stabs his katana into her heart.
The children cry, clinging to her as she feels her death descend upon her body.
The last thing she knows is the familiar high resolution her Sharingan provides and her entire body as if on fire. It is a flame that consumes her from the inside out but is pain and healing.
Kana Uchiha was dying and yet...
She never felt more alive.
