Haruka is a tall girl with brown hair often in two pig tails and orange coloured eyes. She is a curvaceous and well-endowed girl as people in the airport inquired if she was a model.
Haruka is a very energetic girl and, to some extend, childish.
She initially had somewhat of a complex about her height, but as she began playing beach-volleyball, which takes advantage of her tall stature, she overcame it. Also, due to being used to being one of the tallest girls around, she gets uncomfortable around women shorter than her.
