Rin (りん?) is an orphan girl who finds Seshoomaru in the woods after he is badly injured by InuYasha. Although Sesshomaru snubs her, she visits him regularly and attempts to take care of him, even stealing fish from the village for him until she learns that he doesn’t eat human food. The villagers beat her for the theft, but when Sesshomaru idly inquires about her injuries, she seems strangely happy about his interest in her welfare. During this time, she never speaks, only communicating with hand gestures and smiles.
She is killed by Koga’s wolves but Seshoomaru resurrects her by using his sword the Tenseiga. The next time Rin appears, she is clean, wearing a new, colorful kimono, and talking and acting more like a typical child. Throughout the series, she continues to follow Sesshomaru. Though Sesshomaru never states any feelings for her, he displays a strong protective instinct and Rin is obviously devoted to him.
After Naraku’s defeat she lives with Kaede, which InuYasha comments is “practice” for her to live in a human village as an adult, or whatever life she chooses. Sesshomaru visits her and brings her gifts.
