雛子

The youngest of the sisters, Hinako is very much a child and shows her affection accordingly. Hinako frequently insists on her brother reading to her from picture books. Hinako refers to herself in the third-person as "Hina", dropping the "-ko". She addresses her brother as Onii-tama (おにいたま), a more childish version of Kaho's onii-chama. In English, she calls him "Bro-bro". [from [url=http://en.wikipedia.org/wiki/Sister_Princess]Wikipedia[/url]]
