Lilie Shirogane is a main character of the Aikatsu Stars! series. She is a student at Four Star Academy and was previously an admin of the Flower Song Class. As a cool-type idol, her preferred brand is her self-created line Gothic Victoria, reflecting her strong and refined fashion sense. She has always harbored the ambition to design her own brand and eventually becomes its designer, with the blue rose serving as her signature motif. Due to a naturally frail constitution, Lilie spent much of her spring and summer seasons in a rehabilitation facility located in the highlands. In spite of this physical limitation, she trained harder than anyone else at home and developed a composed, self-reliant personality. She is not easily influenced by others and is regarded as a strong and determined individual. In her role at the academy, she is a senior and a member of the student council. As the story progresses into the second season, she accepts Yume's request to continue serving as an executive. During season two, she becomes the second person overall to obtain the Star Premium Pluto Wings, and the first at Yotsuboshi Academy. Her journey is marked by her perseverance through personal health challenges and her creative drive to establish her own brand, which together shape her growth as a designer and idol.
