Luna is a female Netherland Dwarf rabbit Jewelpet with pink fur, yellow inner ears and chest fluff, and jewel eyes made of blue moonstones. She typically wears a blue head bow and a white pearl necklace featuring a blue crescent moon-shaped moonstone pendant; later appearances add hot pink, square-shaped glasses to her design. Her Jewel Charm form is round with a large blue bow at the center, incorporating three moonstones—two small flanking a larger central stone—and vertical white and blue gem detailing. Transformed into a human, she retains pink hair styled with a blue polka-dotted bow, wears pink and blue kilt skirt attire, and keeps her signature glasses. Personality-wise, Luna is characterized as free-spirited yet somewhat selfish, favoring nighttime activities. Early series depict her as generally kind and gentle, often ending phrases with "dana." A significant shift occurs in "Magical Change," evolving her into a clever, studious individual who frequently consults encyclopedias, serving as the intellectual counterpart within her group. Her core magical ability is "Charm Improvement," enabling spells to enhance human appeal, particularly for girls; supplementary materials alternately describe this as enhancing femininity and addressing women-specific issues. Luna's background spans multiple series: In the first season, she partners with human Hanako Kabeno, using magic to create a dress for Hanako’s romantic pursuits—a temporary spell causing public embarrassment when reversed. Later, she works alongside Milky and Peridot as a waitress at the Strawberry Café and participates in Jewel Games. During "Twinkle☆," she and Milky jointly partner with Halite, providing informational segments after episodes. In "Sunshine," she attends the Rose class alongside Diana and Milky; during a trial involving Jewelina Mirrors, her academic prowess gives her an advantage over Labra, but she becomes trapped due to Labra’s error. After rescue, she advocates for Labra’s promotion despite both failing the test. "Kira☆Deco!" positions her as the "Princess of the Moon," residing temporarily with adoptive father Rald before returning to her lunar homeland. "Happiness" depicts her as a mail carrier for Jewel Land’s post office, forming a Magic Gem bond with human Nobara Kitajima. "Magical Change" marks her final major role as one of four primary partners to human Airi Kirara; here, she develops romantic feelings for Airi’s brother, Sakutarō, and becomes integral to restoring human belief in magic. Her departure concludes with her returning to Jewel Land after receiving a gift from Sakutarō. Her relationships include frequent pairing with Milky across series and a familial bond with Rald during "Kira☆Deco!" Merchandise reflects her enduring presence, encompassing acrylic stands, plush toys, charms, and apparel spanning her various incarnations.
