Mikan Shiratama, an 11-year-old female introduced in the series' second season (Episode 39), attends Paprika Private Academy as a sixth grader before transferring to Avocado Academy. There, she rooms with childhood friend Aroma Kurosu. Born October 4 (Libra, blood type B), she has golden eyes and scarlet-red hair. Outside idol activities, her hair is in a short ponytail with an orange angel-wing hairclip. When transformed, her hair lengthens into a high, curled ponytail with face-framing strands, and her height increases. She wears school uniforms featuring wing motifs: initially a winged tie, later Avocado Academy’s winged-back uniform. Cheerful, sweet, and optimistic, Mikan often adopts angelic mannerisms stemming from a kindergarten play. She speaks in third person, ending phrases with "~nano" or "~geru" (from "angel"). Her happy-go-lucky nature pairs with a voracious appetite for meat buns and pudding; sweets and meat buns rapidly restore her energy. Though excelling in sports with high stamina, she tires abruptly if energy depletes, requiring food to recover. Mikan met shy, lonely Aroma in kindergarten. After watching Mew and New’s idol performance together, they dreamed of becoming idols, with Mikan sketching their future personas. When Aroma struggled as a devil in a play, Mikan’s script inspired Aroma’s devilish persona, forging their angel-devil dynamic. They pledged to debut as idols together, forming "Aromageddon." Their bond remains exceptionally close: Mikan helped Aroma overcome childhood timidity, translates her archaic speech, and joins her schemes. A temporary rift occurred in Episode 47 when Aroma disbanded their unit after finding Mikan eating cake with rivals SoLaMi♡Smile. Mikan apologized sincerely, prompting reconciliation and unit reformation. As a Lovely-type idol using the angel-themed Silky Heart brand, Mikan debuted with Aroma without casual coords—a rarity matched only by Falulu. Their unit expanded to "Gaarmageddon" with Gaaruru. Mikan also joins PriPara Police alongside Laala Manaka and Dorothy West. Her coords include Heart Jewel, Silky Heart Cyalume, Gaarmageddon Blue Club, and Super Cyalume Mikan. Mikan holds records: three consecutive Dream Idol Grand Prix wins (a main-character first), zero Grand Prix losses, and no Fairy Change. She is left-handed. Her surname "Shiratama" blends "shira" (white, contrasting Aroma’s "kuro" for black) and "tama" (ball/gem); her given name "Mikan" means tangerine.
