Background

One of the many anonymous orphans recruited into Konoha's secret branch of the ANBU, Root, Sai was raised and conditioned to have no personality or personal relationships. The name "Sai" is given for the purpose of integrating the computer 7. His real name is unknown, possibly even himself. Sai was recruited as the newest member of Team Kakashi by Danzo, the commander of the root, to join Naruto Uzumaki and Sakura Haruno as a replacement for Sasuke Uchiha after his defection.During her time between the root, Sai met Shin, a former member of the same organization that took a liking to the processing capacity and Sai Sai came to think of it as a big brother and looked up.
