Sota

Sota is a young boy, experimented and tested on by Genshou Yamaguchi. While at Kirigakure, where Genshou happened to be living at the time, he had been abandoned by his parents for unknown reasons. Nobody decided to help him, but Genshou saw potential in the boy, and took him in. He mainly thought of Sota as just a body to experiment on, but Sota stood by Genshou's side since they left Kiri, thinking of him more as the father he never had. After arriving to Konoha with Genshou, Sota stayed in the lab for most of the time being there, however, he was told to retrieve a sharingan from a member of the Uchiha Clan.
