Shin

is a fictional character in the anime and manga series Naruto.

Background
One of many nameless orphans recruited into Konoha's secret branch of the ANBU, Root, Shin, like Sai was raised and conditioned to have no personality or personal connections. It is unknown if Shin is his actual real name due to the heavy use of codenames in the ANBU Root Division.

Shin and Sai met during their training in Root. Shin took a liking to Sai's drawing ability, and Sai came to think of him as a older brother and looked up to him. Eventually, his "brother" died of an unnamed illness, and Sai's Root training suppressed most of the memories he had for his Shin. Before the Shin's death, Sai was in the process of drawing a picture book that would show the feelings they shared for each other and all the opponents they faced. Their pictures would start at opposite ends of the book and in the middle both Shin and Sai would be holding hands, but Shin died before he could give it to him.

Personality
Shin has been described by Sai to be very much like Naruto, even though Root members are trained to have suppressed emotions.

Abilities
His abilities are mostly unknown, but Shin has been shown in the anime as　being the top performer in Sai's Root training class.
