Height 172.1 cm Sai is the replacement of Sasuke Uchiha in Team 7. The name "Sai" is given to him for the purposes of joining the team. He was recruited at a young age by Root, which trained him to have no emotions so as to make it easier for him to accomplish missions. This lack of personality causes Sai to meet with hardship upon joining Team 7, as he makes the mistake of insulting the other members in an attempt to seem sociable. He tries to seem more caring by smiling, though his teammates come to dislike it due to his obvious insincerity. 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 to be inspired to give something a title, and thus all of his works are nameless.
