Mishiru is the Prism Show manager of PURETTY. She is very strict with training her girls, but she has a kind side as well. She gets along well with Kyoko Asechi because of their similar professions, but she is not nearly as interested in money gain as she is. 

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.
