Haruka Isumi

Haruka Isumi serves as the powerhouse lead vocalist of ŹOOĻ, an idol unit operating under Tsukikumo Production. Blessed with striking looks and an exceptional singing voice, her past experiences of rejection and denial have shaped a guarded, combative personality—sharp-tongued, proud, and relentlessly driven to prove herself. Throughout the Third BEAT! arc, she channels her fierce ambition into challenging the very foundations of the idol industry. Yet behind the spotlight, she leads a surprisingly grounded life as a high schooler with a genuine talent for cooking and household chores. Beneath her cutting words lies a quietly lonely heart, yearning for the recognition she has never quite known how to ask for.
