Basically, how do you view her (character/personality-wise)? To make it a little interesting, let's try to make it short and simple, try writing just a paragraph.
A shy girl, in her own way, and hence quite private. She doesn't attract attention like some of the other H!P members (for example, Yaguchi), and still remains quite humble and polite even after years of popularity as an idol. Extremely talented in numerous aspects, most obviously in singing and dancing. Though she's matured greatly and has always had a more mature personality compared to her age, she still enjoys having fun whenever she can, is never without a witty comment or two and is still pulling silly faces at the camera.
