Shin

was a Konoha orphan who was recruited into Root.

Background
Even though he was trained to abandon his emotions, Shin grew close to a younger Root member, Sai. He recognized Sai's talent for art, and encouraged him to continue the hobby. Sai looked up to him as a brother and began to shed Root's teachings, but Shin soon died of a disease, leaving Sai's training to suppress most of his memories of Shin. After Sai met Naruto Uzumaki, who he noted to be similar to Shin, Sai's memories of him returned, which brought a smile to his face.

Personality
According to Sai, Shin and Naruto are very much alike. He counted that Shin was loud, impatient, and unrefined. But, despite all these, Shin seemed to be a kind boy, since he often did compliment on Sai's drawings, also always helped him. And because of these reasons, Sai looked up to him as an older brother.

Appearance
Shin had gray hair and black eyes. When he was a child, he wore a pale yellow shirt together with a pair of dark brown pants. These outfits were the ones he wore in the cover of Sai's picture book. When he was older, he wore official uniform of the ANBU, and had a giant shuriken and a tantō on his back. Unlike all other members of Root that wear a short jacket, he didn't.
