She is a high-energy teenage girl who dedicates herself aiming to be number one. Her catchphrases are including "Mia ga Ichiban!", "GA-GAAAAAN!" when she is shocked, and "Ki Do Ai Luck!" (Motivation Passion Love Luck). Although she seems quite dim-witted and straight-forwardly unintelligent, her straight-forwardness and simpleness are what keeps her going. Everyone in Prizmmy knows that Mia has a bad way of saying things, but she means no harm towards anyone. She never lies and always plays by the rules. Mia is always encouraging others and always keeping things positive.

Three years after the events of "Pretty Rhythm: Aurora Dream," Aira, Mion and Rizumu have grown up and tutor a new group of aspiring idols: Karin, Reina, Mia and Ayami, who form the Prizmmy&#9734;. Teenage girls from Korea, named Somin, Shiyoon, Haein, Chaekyung and Jae Eun (who are the PURETTY), appear as a rival group.

PriPara Movie: Minna Atsumare! Prism☆Tours is the film based on and starring the characters from PriPara. The film first began showing in theaters across Japan from March 7th, 2015. The plot focuses on Laala Manaka finding out about Saints' top idol journey, and aside from the PriPara performances, the movie also features the journey of characters across all the Pretty Rhythm series.

At some point in the movie, the characters are given a choice of four doors to go through. At this point, the movie diverges into one of 4 routes depending on what the audience chooses. Each route recaps different aspects of the previous Pretty Rhythm series, mainly reintroducing the different characters and their performances. However, Laala and friends only get a chance to enter one door at a time, meaning the film must be watched four times to view each door choice.
