- Rin has long, dark brown hair, which has been tied in a ponytail. Behind her bangs she wears a small yellow bell, tied with small white ribbon. Rin's eyes are brown with a red shade in the anime and clear red in the visual novel. She is wearing the same, usual uniform as the other girls.
- Rin is the main heroine in the story. She is the younger sister of Kyousuke Natsume and is the only female member out of the five original members of the Little Busters. She does not communicate well and is seen as inarticulate. Due to this, she is anti-social, and is usually seen alone. When playing baseball with the others, Rin is an ace pitcher, although she used to be quite a bad pitcher - her throws would go in completely unpredictable directions - until she gets into a baseball stand-off between Sasami Sasasegawa, where she demonstrates two "super-power" pitches, where one of them is a fastball and the other one is her own version of a changeup(in the visual novel she performed two fastballs(130 and 135 km/h) which lured Sasami to swing too early when Rin launched a slowball, earning Rin a strike-out). She is one of the two initial survivors of the bus accident.
- Rin loves cats and at school takes care of several strays; it is not uncommon for several cats to crawl onto her. One such extremely overweight cat she named "Akinori Dorj", other, much smaller, cats she has named "Hitler"(that name has been changed in the anime, but exists in the visual novel), "Fabre", "Tezuka" and "Isoroku". Rin often has a white kitten named "Lennon" with her which rides either on her head or shoulder.
- Rin's name means "bell", and she wears a bell in her hair.
- Her English voice actress, Brittney Karbowski, has also voiced characters in previous Key anime series, including Ryou Fujibayashi in Clannad, Ayu Tsukimiya in Kanon, and Yuri Nakamura in Angel Beats!
- She has given Masato several nicknames like, Trash, Retard, etc. She gained a title given by her brother Kyousuke herself: during the first baseball practice she gets the title "Godly Lack of Control", however in the visual novel if her first route is completed so her skill is better; she gets the title "An Ordinary No-Con" instead.
- "This guy's an idiot." (Episode 01)
- "Come on, come on. What now, Isoroku? Guts! Guts! Be the first in history to walk on two legs!" (Episode 02)
- "That wouldn’t be fair... I just need to clear the task, right?... We'll find out what they want to tell us." (Episode 02)
- "There must be something... I can do too!" (Episode 06)
