Sasuke was training intensely in his family training ground as he had one goal in his mind and that was to kill Naruko and Satsuki.
Naruko that blonde haired bitch who not only made a Sasuke look like a complete fool when she had defeated him with little to no effort but she had the gall to make fun of Sasuke because he hasn't unlocked his sharingan yet.
I'll show you your place you worm" Sasuke said as kicked a tree breaking it in half as he imagined that the tree he broke was Naruko but that wasn't enough to satisfy his anger as he set his sights on another tree as he imagined that he was killing his twin sister Satsuki.
Oh how Sasuke hated the family princess Satsuki, at the age of three Satsuki had managed to unlocked her sharingan and immediately she was the center of attention in the Uchiha clan, whenever Sasuke does something wrong his parents would always compare him to Satsuki and he hated it.
He wanted to be clan heir so bad but no the title goes to Satsuki who of course is much stronger then Sasuke but all that will change.
Once I've obtain the power I so desperately need you better count your days Satsuki and Naruko because I will give both of you the most painful death ever known to man" Sasuke said as he left the training ground as he was unaware that he was being watch by a mysterious hooded figure.
