Itachi was eating lunch alone and, he was alone cause he perfected everything. From ninja training to common core. He was just eating lunch minding his business when these two kids from higher grades came up to him. They starting talking ill about the Uchiha clan witch almost caused him to attack them with his kunai when a girl stood up for him.
She stood up to the older kids!
"Leave him alone! I'm also and Uchiha!"
School was over so Itachi left. He ran into the two of the older kids. They wanted to fight him but, Itachi didn't. Exceptionally he was willing to do it in the art of self defence But, to Itachi's surprise they pulled out kunai. Itachi not that scared was about to grab HIS kunai until the same girl from earlier popped out. She got so mad and furiated that she unleashed the Sharingan. Itachi was devastated. He was better than her at everything but, he still wasn't able to unleashed sharingan.
"Leave us ALONE!"
She has Sharingan!
The girl past out due to her being way to under skilled which meant Itachi had to carry her or in reality drag her to the nurses office. there she explained how and why in her own theory on what happened. Her dad died by nine tails attack, giving her grief of not being strong enough so all of a sudden she was able to use there handed down technique, Sharingan.
"You see my dad..."
