Last sketch of tonight. I will colour this in the morning ^^.
Sora Is Error and Gaara's First child. He is named after his grandmother on his mother's side. he is two years younger than his cousin Shikadai though he graduates to Genin close to the time his cousin does. Sora inherits his father's skill of Sand manipulation but also trains to hold control over gold dust also. He also carries over his mother's ability in Taijutsu as she taught him which used with his sand is a lethal combination.
Karura is Error and Gaara's Second child. She is named after her grandmother on her father's side. She is 4 years younger than her brother but she does not become a ninja though she inherits her father's Jutsu style and is taught how to defend herself with sand.
If you want to know more about these two that are early days but i can fill you in with info if you like.
