She appears as a playable character in Ryuu ga Gotoku 5 but participates in rhythm game-based dance battles in contrast to the other protagonists.
Haruka is a girl who is taken into care by Kiryu Kazuma during the events of Ryuu ga Gotoku 1 and eventually becomes Kiryuu's adoptive daughter after the events of the game. She is a self-reliant mature girl for her age but still retains her childishness during her younger years.
