Karin is a former suborniate of Orochimaru of Otogakure, a former kunoichi of Kusagakure, now a genin-level kunoichi of Konohagakure, a Human who gain Soul Reapers powers, and recruited to the Chikaku Squad (Temporarily called Team Tsunaku).
In Part I (Kaipuden), Karin has rose pink eyes, matching hair color, and an unusual hairstyle: her hair is short, pointy, and unkempt on the right side, while it is long, pin-straight and combed on her left side. She wears brown glasses, formerly, a lavender uniform common for Orochimaru's subordinates, short black shorts, and long black thigh high stockings with black sandals. Her chest, neck and arms are covered with bite marks that result from using her Heal Bite, and all of which are hidden by her uniform.
As she is allied with Konoha, Karin begins to wear a pouch around her midsection, and later a black cloak. she wear a red shirt with a pink accessorie similar to the shirt she wored in the Chunin Exam.
In Part II (Shippuden), Karin briefly put her hair in a ponytail.
As a child Karin lived in a small village that was burnt to the ground during a war. She was the only survivor and was completely unharmed. Orochimaru found her afterwards and asked how she survived, to which she answered that she could tell that huge groups of people were coming. Orochimaru then brought her to Otogakure, where she served as a jailer at one of his bases. Karin eventually took part in the Chunin Exams that were held in Konoha. During the second phase, taking place in the Forest of Death, she lost track of her team-mates and was attacked by a large bear. She was saved by Sasuke Uchiha who was disappointed to find she had the earth scroll as well, but she was able to catch a good glimpse of him before he left. She remembered the smile that Sasuke gave her.
