The Dark horse, (Sasuke Uchiha x Reader)

The L/n clan was massacred when y/n was just 6 years old, one year before the Uchiha clan's massacre.
The clan possessed unique physical abilities. They have the ability that grants them extra horse-like traits. It gives them powerful leg strength (so they love their split-kicks), incredible speed like a thoroughbred, the stamina of an Arabian, and the agility of a Quarter horse.
But their extra abilities are special. There's a select few who possess the l/n clans true power, but all of the l/n clan have the purple color changing eyes, which activate when the user wants too. Reference image in story.

When the eye is activated, it glows purple. Their traits are similar to the Uchiha's Sharingan, when using it they can track high-speed movement that normal eyes can't follow, but instead of their eyes progressing like a Sharingan, a select few are born with a unique power:
80%: No extra power.

10%: Fate reading eyes, sees possible outcomes a few seconds into the future.

5%: Emotion weaponizing eyes, converts emotional states into power boosts: fear=speed
rage=strength
resolve=defense

1%: death awareness eyes, sees how close a person is to death. It's not a timer, it's a presence. Near-death shinobi appear distorted or flickering.

0.0001%: ???Unknown abilities??? This power only can happen when mixed with the Sharingan. It comes from evil, being compared directly to the devil. Only known information is that when activated the user's appearance changes to something more devil-like.

Because of the l/n clan possessing such power, they were all killed. Leaving only y/n alive, much like how only Sasuke was left alive. But unlike Sasuke, y/n was not protected by anyone. How she survived the massacre is unknown.
