She is one of Maya's childhood friends and the secretary of Seashell Bay Middle School's student council. Her alter ego is Glitter Diamond. (Cure Diamond in Doki Doki Pretty Cure!.)
Rachel has dark blue eyes and chest-length, navy-blue hair worn loose with a braid on each side of the head held back by a ribbon. Her bangs are layered in length to frame her face. She wears red glasses. She wears a white long sleeved blouse with crimped lines and ruffles at the middle, worn beneath a light blue pleat dress with a buttoned band beneath the chest and frilly petticoat. At the neck is a blue ribbon. She also wears black socks with brown boots. For summer she wears a white tunic with a light blue collar and skirt. Around the bottom of the dress is a sideways blue diamond pattern accenting her striped sleeve cuffs and the bow hanging from her neck. This is paired with white socks with a frilly cuff and black flats.
As Glitter Diamond her eyes and hair brighten in colour while her light indigo hair grows in length and is worn in a thick, high ponytail with a large curl on end, followed by four separate curled strands. Her ponytail is held by a blue hair piece lined in dark blue and trim with feathery fabric. A dark blue diamond rests on it to match her earrings. Her dress is sky blue with indigo lining the top of the chest and two strands of frilly fabric lining on the chest and shoulder. A white and indigo striped band is diagonally sewn at the corner with a blue ribbon on the right hip where her Glitter Pad rests. A sapphire gem heart with a white ribbon rests on the left of the chest. The white sleeves feature a single puff with a gold band around it, while the other resembles a small wing. The skirt of the dress resembles a pair of white wings and is spread open to reveal short white wing-shaped material that has a single line of sky blue on it. She also gains white boots with a sky blue opened cuff and a gold band to match her bracelets and choker.
Rachel is an intelligent girl who is often quiet, but she is blunt and is not afraid to speak her mind. She loves to study and is one of the top ten scoring students in the national trial exams. As noted by Maya in episode 9 of the first season, Rachel is at the top of the class and constantly placed as the first place in her school, however, her scores started to drop as she was in second place because of starting to play competitive spelling bee, as it was seen in episode 14.

Rachel is Maya's best friend and they have known each other since elementary school. She always tries to stop Maya from overdoing things but cannot seem to do so. Her mother works late at a local hospital and her father travels the world as an Photographer.
