Sai is a Chūbu of Konohagakure's Yamanaka clan. Prior to this, he was an Anbu from Root. As per standard Root training, Sai was conditioned to remove all emotions and as such, had difficulty connecting with others. When he is added to Team Kakashi as a replacement for the rogue Sasuke Uchiha, Sai begins to learn more about people's feelings and tries to develop his personality and identity by forming genuine bonds and rediscovering the emotions he was taught to suppress. Sai is a talented artist, and claims to have drawn thousands of pictures. Despite the magnitude of pictures he has drawn, his lack of emotion makes it impossible for him be inspired to give something a title, and thus all of his works are nameless.
Naruto
Moments prior to Naruto Uzumaki's birth, a huge demon known as the Kyuubi, the Nine-Tailed Fox, attacked Konohagakure, the Hidden Leaf Village, and wreaked havoc. In order to put an end to the Kyuubi's rampage, the leader of the village, the Fourth Hokage, sacrificed his life and sealed the monstrous beast inside the newborn Naruto.
