Mahiru Tsuyuzaki is the tritagonist in the Shōjo☆Kageki Revue Starlight franchise. She is a second-year student from the Actor Training Department at Seisho Music Academy's 99th Graduating Class. Though she sings and dances her heart out on stage, this Stage Girl is normally withdrawn and contemplative. She admires her roommate Karen's cheery and outgoing nature, but her feelings are put in a difficult place when Karen's old friend Hikari shows up.
