Chiaki is a prep student at Kouka School of Musical and Theatrical Arts. She's Chika's twin sister, and the two are genuinely close—the kind of pair who can read each other without saying anything. Chiaki's pretty straightforward about what she thinks and generally comes across as upbeat.
She's got her sights set on playing musume-yaku roles, the female leads. That said, she had a rough patch early on—she failed her entrance exam while Chika passed it on the first try, which hit her hard guilt-wise. But she bounced back and got in during her first year of high school.
