Erika's a second-year at Shuchiin Academy, where she hangs out in the Mass Media Club with her friend Karen. She comes from money—her parents own the Kose Miso Soy Sauce Company—but honestly, that's not what defines her. What really matters is her completely unhealthy obsession with Kaguya. We're talking fainting-just-from-being-near-her level of devotion. She's basically Kaguya's number one fan, though Kaguya probably finds it uncomfortable.
