Uchiha Kyodai

The Face Becomes the Mirror to the Soul

Kyodai falls more in love with her sons every day. They look just like her father. Curly hair (less curly than hers), kind smiles, playful expressions, long eyelashes, large eyes, broad noses, shoulders, chins, and jaws, shapely lips, flat cheeks, and even their slightly pointed ears. They are cheerful and polite, mischievous but respectful, and Kyodai thinks she's done a good job. That's why it terrifies her when they turn eight and join her on the battlefield. She doesn't want to lose them. They are the light of her life. Perhaps she is selfish. That doesn't shock Kyodai.

She had let go of her hate for the Senju years ago. Now she dives down deep to grasp on to it, not caring if she drowns. Kyoto, her son, her son was dead, was dead. Kyodai thinks of how small, precious, and bright he was and screams, sobbing the loudest she ever had in her life. Her Mangekyou spins to life and the clearing becomes a nightmare. The Senju, oh how she hates them, are paralyzed by fear. Her face promises vengeance. They know they are going to die. Kyodai uses her gift of sharing, and they feel it before it happens. The only survivor is a white haired man with red eyes. Kagami finally understands why his mother is feared. Understands why she didn't want him or Kyoto to be like her. He promises that he will always love her, and that he will not become her. Kagami makes good on his promise.

Tobirama seemed to be scared of the Mangekyou (rightfully so) and the Uchiha's hate, but it was never really elaborated on why. That's what this is. Kyodai has some sort of twisted charisma.

P.S. Both Kyoto and Kagami mean mirror.

I do not own the Naruto series.
