Movie
Description
Yuni, alias Blue Cat, Mao, and Bakenyan, is a shapeshifting alien from Planet Rainbow, whose population was petrified during Aiwarn’s invasion. As the last of her kind, she assumes diverse identities to infiltrate factions like the Notraiders, reclaim stolen artifacts—including the Star Color Pens—and resurrect her world. Haunted by guilt over her planet’s demise, she masks her vulnerability with cunning, operating as the phantom thief Blue Cat to orchestrate elaborate heists using fireworks and calculated bargains, while maintaining a cheerful idol persona as Mao. Her isolation stems from a self-imposed burden to undo the catastrophe alone.

A pivotal theft of Fuwa, a fairy tied to reviving the Star Princesses, forces her into conflict with the Pretty Cure team. When cornered, she unveils her true form and tragic past. Her resolve shifts after shielding the team from Aiwarn, earning Fuwa’s trust and the Star Color Pendant, which transforms her into Cure Cosmo. Wielding the Rainbow Perfume and techniques like Cosmo Shining, she embodies the Pretty Cure of Space, her rainbow-themed attire and feline motifs echoing her alien heritage.

Her evolution centers on shedding guilt to embrace teamwork. Initially morally ambiguous—stealing for noble ends—she gradually aligns with the Cures’ collective ethos. A complex dynamic with Aiwarn unfolds: though responsible for Rainbow’s ruin, Yuni purges Darknest’s corruption from her foe, later aiding Aiwarn’s reintegration into society.

In *Hoshi no Uta ni Omoi wo Komete*, she aids in safeguarding UMA, a volatile star-shaped alien, prioritizing universal stability over personal goals. Collaborating with Lala, she neutralizes threats from interstellar hunters, showcasing her growing camaraderie.

Relationships evolve from distrust to solidarity: Prunce transitions from idolizing her Mao persona to forgiving her deception, symbolizing her acceptance into the group. Her bond with Fuwa deepens from pragmatic use to genuine kinship. By the series’ end, Planet Rainbow’s restoration and her partnership with Queen Olyfio cement her redemption, completing her journey from solitary avenger to guardian of cosmic unity.
