Hinako

The youngest of the 12 sisters and a young child, Hinako (commonly nicknamed Hina) likes to play with her brother and have stories read to her by him. She refers to herself in the third person as "Hina", dropping the suffix "ko" in her name. She calls her brother Onii-tama (おにいたま), a childish way to call one's brother and a more childish version of Kaho's onii-chama (お兄ちゃま). In the English dub of the anime, Hinako calls him "Bro-bro."
