Renji is the 1st born child of Tetsu and Omori Kaguya. He is very loved by his parents, but he struggles to connect with them as he was born without the capability of feeling regular Neurotypical emotions. The boy is similar to his younger brother in that they are both very withdrawn from their peers. Renji is arrogant and thinks that he is better off by himself in battle. The thing that sets him apart from any of his family members is that he has a unique ability to blend in with any background, sort of like a Chameleon which makes him the perfect spy. Seeing as the boy is not really fit to be a regular shinobi, he was surrendered to the Anbu Black Ops recently after turning 11, abandoning his family to train under Kisayo Hiroyashi, the Head of the Anbu Black Ops in his village. One thing they teach the new recruits is to not be emotional as it will hinder the individuals' ability to think critically in high-stake missions. This role is suits him as he already has disconnected from the norms of the shinobi world. Since joining, he has made 1 friend. The only friend he has ever had. Her name is Ayame Mizutani, a member of the Mizutani Clan. As Renji is part of the Anbu, he has adopted the name Shinra, and Ayame goes by Miyo.
