Haruka is the all-around good girl and main heroine in The Idolm@ster. She has enjoyed singing and making sweets since she was a child, despite the fact that she seems to be quite inept as a cook in general. She is easily excited and a bit clumsy, admitting herself that she usually falls down somehow at least once a day. However, Haruka remains positive and keeps a strong resolve, always working the hardest to make the Producer happy. Also, although her character image color is red, personally, Haruka actually tends to be more partial toward the color pink (which is Iori's image color). Her Image Song in The Idolm@ster is Taiyou no Jealousy, but it becomes I Want in The Idolm@ster SP. She shares Watashi wa Idol as an image song in the Xbox 360 release of the game with Iori Minase.
