Although Rin's normal card has low basic stats, she was the first extra idol to get an extra S Rare card, and that card is extremely powerful. Since she goes from an unremarkable character to a star so quickly, she can be thought of as embodying the true spirit of the Cinderella Girls project.
She has received five sets of S Rares and a special S Rare+ card only available in Lawson stores. Her S Rare titles are "New Generation", "Pure Valentine", "Iolithe Gothic", "Banquet Diva", "Wonderful Magic", and "Cool Summer Vacation".
She is voiced by Ayaka Fukuhara (福原綾香 Fukuhara Ayaka).
Rin tends to come off as unfriendly-looking, a flaw that she is conscious of. She can be slightly distant at times, but is a friendly girl who works hard. Her parents own a flower shop.
