Rom, also known as one of the White Sister, is one of the protagonists in Hyperdimension Neptunia: The Animation. She acts as one of the CPU Candidates of the nation Lowee and is also Blanc's younger twin sister along with Ram.
Rom is rarely ever separated from Ram and does just about everything with her. She seems to represent Blanc's quiet side.
Out of the twins, Rom looks the most like Blanc, even though she still love pulling pranks with Ram. She wears a blue overcoat with white puffballs, a pink handbag and a ribbon, and a white and blue hat to match with a pink rectangle in the center. Her leg-wear consists of white tights and shoes that match her dress in design. She has shoulder-length brown hair and steel blue eyes, much like her older sister.
Rom seems to be very quiet and possibly even shy in comparison, and doesn't say much. Rom sometimes seems upset or nervous by how Ram acts or what she does, but otherwise she lets Ram do as she pleases with her. Though Rom has also shown signs of exerting how own free will.
Rom's appearance is similar to that of White Heart's. Both share the same light blue hair color but Rom's eyes are pink instead of red. She wears a one piece bodysuit that is white in color with a secondary color of pink on the arms, legs, and torso.
While Rom is normally soft spoken and shy, when she activates Hard Drive Divinity (HDD) and becomes White Sister she starts to speak up louder (though still speaking softly for the most part) and sounds far more serious and confident in her abilities.
