Lisa Shirakaba is a supporting character in the crossover film Aikatsu! x PriPara THE MOVIE -Deai no Kiseki!-, representing the Aikatsu! side of the story. She is a sexy-type idol who hails from Hokkaido and uses the brand Dolly Devil. Originally introduced as a rookie idol in the Aikatsu! television series, she debuts alongside her best friend Nono Daichi, and the two share a close bond that carries into the movie. Lisa has a calm, collected, and level-headed demeanor, often keeping a rational perspective even when the unusual dimensional crossover between the Aikatsu! and PriPara worlds occurs. She is generally comfortable in her own skin and rarely shows strong passion, but when something genuinely excites her, a determined fire appears in her eyes. This can make her seem reserved at first, and she is prone to embarrassment when others point out childish or trivial habits in front of new acquaintances. In the film, Lisa’s role is to support the main Aikatsu! cast as they navigate the merging of the two idol universes. She joins in the collaborative live performances and helps bridge the gap between the two groups through her grounded yet dependable nature. Her primary relationships are with Nono Daichi, whose energetic personality contrasts with her own calmness, and with the other Starlight Academy idols, particularly those she has worked with before. Lisa’s abilities center on her sexy-type idol performances, which rely on poise, graceful stage presence, and the Dolly Devil brand’s fashionable coords. While not a central protagonist in the crossover, her steady personality and friendship with Nono provide a reliable anchor for the ensemble cast. Over the course of the story, she demonstrates a willingness to cooperate with unfamiliar PriPara idols, showing her adaptability and quiet growth as an idol.
