Name: Uchiha, Kotouru(last name,first name)
Age:12
height:5 foot 3 inches
personality:Silly at many times,but you can be very serious. If someone makes you angry they better be hopeful that your in a good mood. Your perspective on your clan being wiped out would be, you were furious and cried every night since then,but now have gotten over it.
History:Your parents names are Kurinae Uchiha(mother) and Sentea Uchiha(father), you were an only child. Your father was has a background from the Water village,which had an Uchiha clan back then, your grandfather was part of that clan. Unfortunately by oath you had to have a water spirit sealed within you. So when you were 4, you were taken to the Water village and have Kiseki(the woman water spirit)sealed inside of you. Your mother had a history with the Lightning village and their Uchiha clan. Before you were born they moved back to Konoha and had you. Being a female you were enabled to have a special chakra ability or abilities, you had lightning sword,chakra ball and more(explained later).
How you survived from the clan being wiped out: It was after the academy let out and at the time you were only eight years old. When you came inside you immediately went to your room and studied jutsus. Then you heard people outside screaming and so you hid under the bed,because you heard your parents scream after that. Fortunately the lights were off,once Itachi walked in he looked for you but couldn't find you, because of your water Spirit your parents engulfed your walls in chakra. So Itachi looked for your chakra but couldn't see it. As he left you ran and looked out the window there was sasuke Uchiha, your child hood friend.
How you know sasuke:You've known him since he was born because your birthday was March 15 and his was July 23. Your parents were very close with his. He was your only friend because everyone made fun of you for your seal mark. But Sasuke didn't care one bit, he told you that you'd both be friends forever,until Itachi did the unthinkable. When you saw sasuke being taken away from the anbu you wanted to go but were too scared for four years since then you have been hunting and training by yourself.
