Although her full name is Hinata, she likes people to call her Hina. Sixteen-year-old Hina gets excellent grades, but is still very naïve and sees the world with child-like wonder and innocence. Hina chooses to live on her own, with two teddy bears named Waka and Tono and her new found friend, a cat. She wants to live on her own to accommodate her father's hectic schedule.
Her father is the chairman of the school and he also owns many businesses. He hires Shirou Asou, a bodyguard, to protect her from another kidnapping attempt (she had been kidnapped nine times before). Because her father always pays the ransom, no matter how large, Hina has been kidnapped many times. She later develops deeper feelings towards Shirou.
