Description
Rachel Bennett (Hishikawa Rikka in the original Japanese) is a main character bound by deep childhood ties. She shares a long-standing neighborhood friendship with Maya Aida, established since elementary school; Rachel habitually checks Maya's impulsiveness while depending on Maya's protective instincts, forging profound mutual trust. Clara Yotsuba, another elementary school friend, completes her core circle. Academically, Rachel excels, ranking among the nation's top ten in mock exams and consistently first at her school, though a spelling bee participation later temporarily placed her second. Her mother works late hours at a local hospital, and her globe-traveling photographer father stays connected through letters.

Rachel possesses dark blue eyes and dark blue hair, typically styled with sections plaited into two back braids secured by a pale blue bow. Her swept-aside bangs sometimes leave strands on her forehead, and she occasionally wears red glasses. Her standard outfit is a white shirt paired with a light blue dress and brown shoes, switching to a white and blue sailor dress in summer.

Her path as a magical warrior starts when Maya, struggling to keep the team a secret from her best friend, reveals its existence. Rachel later encounters a mysterious merchant who gives her a Glitter Charm. Choosing to use it to aid her friends, she transforms into Glitter Diamond. Her transformation partner is Rory (Raquel in Japanese), a dog-like fairy who assists and develops a crush on her. To activate her transformation, Rachel places her Glitter Charm onto Rory's silver heart medallion, declares "Glitter Force Makeover!", and traces L-O-V-E on her Glitter Pad. This triggers a glow: her hair grows into a light indigo knee-length ponytail adorned with a heart medallion-tied bow and diamond earrings, while her combat attire materializes—a light blue dress with white winged sleeves, gold clasps, white frills, dark blue accents, and white boots featuring milk blue cuffs. Her transformation catchphrase is "The light of wisdom! Glitter Diamond!". Representing wisdom and the diamond suit, she wields ice-based powers. Her combat techniques include group attacks: "Togetherness Power Arrow" (with Glitter Heart, Clover, Spade), "Five of a Kind Glitter Bow", and "Royal Lovely Straight Flush" (both with the full team including Glitter Ace). Power-ups manifest as a blue light enveloping her body.

Rachel's character development involves overcoming jealousy towards Mackenzie Mack's growing closeness with Maya, leading to solid friendship. A significant season 2 arc centers on her discovering Ira unconscious on a beach. Defying Glitter Ace, she protects and cares for Ira, believing in his potential for goodness despite his antagonistic past. This protective bond becomes reciprocal, with Ira later shielding her and warning her about threats like King Mercenare. She is characterized by calmness, responsibility, and intelligence, though she exhibits suspicion toward strangers, especially those offering unsolicited items. She openly acknowledges her lack of athletic prowess, often being last chosen for sports teams.

Her theme color is blue, her birthday is September 17, and she was initially the only season one team member without a confirmed last name. Her Glitter Diamond design incorporates feather-like elements for an angelic aesthetic.
