Rin is a 15 year old girl who loves walking dogs. Her most prominent feature is long straight hair and her color image, which is black. Although pretty, she does not really smile much and gives off a very unfriendly aura to her peers around (which she realizes). Despite that, she still likes wearing cute costumes, given her personality.
Her stats in the game (among Normal cards) is among the lowest within her category, although her cost is still on the balance side.
With the addition of her Rank S Rare card into the Platina Gacha selection on January 13, 2012, her stats are one of the strongest in the rank S category cards, which makes her one of the Cinderella Girls in the game.
She is the first character to have a speaking role in IDOLM@STER Cinderella Girls, where she spoke a line in one of the commercials.
However, the seiyuu for her was never announced. While Azumi Asakura, the seiyuu for Yukiho Hagiwara did mention her appearance together with Rin's seiyuu, the seiyuu for the commercial's narrator and Rin were not revealed.
Along with the announcement of the first CINDERELLA MASTER CDs, it was revealed that Rin's seiyuu is Ayaka Fukuhara.
