She is the student council president of Uranohoshi Girls' Academy, and the older sister of [[Kurosawa Ruby]]. Dia is a member of the Aqours sub-unit [[azalea (love live!)|AZALEA]], alongside [[Kunikida Hanamaru]] and [[Matsuura Kanan]].

She has [[aqua eyes]], [[long hair|long]] [[black hair]] with [[blunt bangs]], and a [[mole under mouth|mole below her mouth]].
