Rin is an eight year old orphan girl who finds Sesshomaru in the woods beneath a huge tree.. After her entire family was slaughtered by night robbers, Rin never speaks, only communicating with hand gestures and friendly smiles. When various wolves are sent by Koga, killing and eating the villagers, Sesshomaru finds Rin's lifeless body and revives her using Tenseiga. After this, Rin starts to speak and remains in company with Sesshomaru, Jaken, and A-Un. Throughout the series, she is known for her kindness and loyalty to Sesshomaru, even though he's a cold and uncaring demon. She believes that men are more evil than demons because human robbers killed her entire family. In the Final Act, she causes grief and great sadness to him when she dies so in a way, Rin brings out the best in Sesshomaru who never shows to other people his feelings for Rin, but he does have them. Rin also has a good relationship with Kohaku, as she tells him what about her family's murderous death. Kohaku tried to kill her when under Naraku's mind control, but once free, he became Rin's best friend and protects her along with Sesshomaru. She is able to fully control A-Un and is recognized as his main master, as shown several times in openings and episodes that Jaken cannot fully control the beast, even though he got him first. At the end of the series and either ten or eleven, Rin is adopted to live with Kaede, although Sesshomaru is shown often visiting her and bringing her gifts. Inuyasha stated that she is in the village to practice to return to a human village or whatever she chooses.
