Rin serves as an attendant in the spirit realm's bathhouse, handling customer service and maintenance. She initially meets Chihiro in the boiler room, refusing help due to personal risk until Kamaji bribes her with a roasted newt. Rin then guides Chihiro through the bathhouse, using the newt to distract a frog worker and prevent Chihiro's exposure as a human. After Chihiro becomes employed as Sen, Rin is assigned as her supervisor and caretaker. Though initially annoyed by the responsibility, Rin privately shows relief and support, supplying work clothing and guidance. She advises Chihiro to distrust Haku, calling him Yubaba's henchman, and comforts her when unwell. Rin assigns Chihiro to clean the large tub, demonstrating the water system using an herbal soak token. During the River Spirit's cleansing, she assists by tying a rope around a protruding object and coordinating staff to remove pollutants. Rin later enthusiastically informs Chihiro about No-Face distributing gold, urging her to collect it while dismissing concerns over Haku. Following No-Face's rampage, Rin finds Chihiro in the boiler room, conveys Yubaba's anger about No-Face's entry, and expresses shock at Boh and Yubaba's bird's transformed states. She rows Chihiro to the train station, warning No-Face not to harm her, and celebrates visibly when Chihiro passes Yubaba's final test. Physically, Rin has brown eyes and long brown hair tied with a pink ribbon. She wears the standard salmon-colored jinbei uniform with a yellow undershirt, a blue apron, and remains barefoot. Conceptually, early drafts described her species as a *byakko* (white tiger or fox), though this was revised to a human presentation. Rin exhibits a strong-willed, occasionally sarcastic demeanor, frequently using blunt or critical language. Her protective instincts emerge through actions like shielding Chihiro during the River Spirit encounter and advocating for her safety against No-Face. Her dialogue includes pragmatic statements, questioning Chihiro's work experience and expressing frustration over tasks like tub cleaning.
