Otome Arisugawa, a vibrant pop idol under the Happy Rainbow brand, lights up Starlight Academy with her bubbly charm. Her carefree spirit shines through frequent declarations of "Love You" and the affectionate "-tan" honorific for friends. Sporting ginger hair coiled into drill-like chignon buns and striking vermilion eyes, she embodies the academy’s style in her signature uniform.

Raised in her family’s kindergarten, Otome honed her nurturing instincts early, aiding childcare before chasing her idol dreams at Starlight Academy. Her ascent sparked a fiery rivalry with Ichigo Hoshimiya, marked by a climactic Christmas audition duel and triumphant Revenge Live showdown. Later, she co-created the dynamic unit Powapowa-Puririn and claimed the Starlight Queen crown, stepping into Mizuki Kanzaki’s legacy.

Driven by relentless dedication, Otome tirelessly prepared for performances, undeterred by occasional stumbles. Childhood acrophobia gave way to daring feats like scaling trees for animal rescues. Bonds with Sakura Kitaōji and Shion Kamiya anchored her journey, while her once-contentious rapport with designer Makoto Nijigahara blossomed into mutual admiration—complete with his adoption of her signature phrases.

Career highlights span electrifying units STAR☆ANIS and Aikatsu8, dual renditions of Powapowa-Puririn’s debut anthem, and crossover appearances in *Aikatsu on Parade!*. As Pop'n Popcorn’s spirited mascot and a master of animal impressions, she carved a distinctive niche in the idol world.

Born May 5 under Taurus skies with blood type B, Otome savors sweets—popcorn and burgers—but shuns green peas. The imperial-rooted surname Arisugawa ("exist-roast-river") pairs with "Otome," meaning "maiden," reflecting her elegant yet fiery persona.
