TV-Series
Description
Rachel Bennett, called Hishikawa Rikka in the original Japanese version, anchors the series as a central character. Her civilian life showcases a disciplined 14-year-old student with dark blue hair typically braided and fastened by a pale blue bow, sometimes accessorized with red glasses. She favors a white collared shirt with a blue bowtie, a light blue pleated dress, black or navy socks, and brown boots, transitioning to a white-and-blue sailor dress in summer.

Academically, she consistently ranks in the national mock exam top ten and serves as student council secretary, though her scores occasionally waver during commitments like competitive spelling bees. She exudes a calm, studious, and responsible demeanor, habitually tempering the impulsiveness of her childhood friend Maya—a dynamic rooted in their elementary-school bond. Her mother works night shifts at a local hospital, while her globe-trotting photographer father stays connected through letters.

After Maya reveals the team’s secret, Rachel obtains a Glitter Charm from a merchant, unlocking her transformation into Glitter Diamond. This identity embodies wisdom, proclaimed in her catchphrase: "The light of Wisdom! Glitter Diamond!" Her transformed state reveals light indigo hair in a knee-length ponytail with curled strands, diamond earrings, and a gold choker. She dons a light blue dress with white winged sleeves, gold accents, and white boots. Activation demands spelling "L-O-V-E" on a Glitter Pad while declaring "Glitter Force Makeover!"

As Glitter Diamond, she commands ice-based powers and joins pivotal group attacks: "Togetherness Power Arrow" (with Glitter Heart, Clover, and Spade), plus "Five of a Kind Glitter Bow" and "Royal Lovely Straight Flush" (with Glitter Heart, Clover, Spade, and Ace).

Beyond the team, she shares deep ties with elementary-school friends Maya and Clara. Initial jealousy over Maya’s bond with Mackenzie evolves into steadfast friendship. Her transformation partner Rory nurses a romantic crush on her, sparking frequent flusters. A turning point unfolds in the second season when she discovers the antagonist Ira unconscious on a beach. Defying her teammates, she shelters and heals him, forging a complex rapport where he shields her from threats. This choice also catalyzes a power enhancement gifted by Glitter Ace.

Her birthday falls on September 17, marking her as a Virgo. Thematically, her Japanese name "Hishikawa" blends "diamond shape" and "river," while "Rikka" means "snow" (from characters for "six" and "flower"). In the English adaptation, she stands as the sole first-season team member lacking a confirmed surname.
