Hina Mishima

Hina is strong and genuinely kind with a big sense of justice, but also a bit naive. She is not very academic but has spectacular athletic skills. Her parents divorced when she was 5 years old. At 7, her mother was run over by a car right before her eyes. This event traumatized her severely and caused complete memory loss. She also fell off a bridge and hit a tree at 10 meters, which may have exacerbated the damage. Hina goes to live with her uncle and leaves her hometown. 10 years later, they return and she starts to attend the local high school. Appalled by the current state of affairs at this school, she declares a war against the leaders of the Blacks and Whites. Hina is nicknamed 'Piyoko' (baby chick) by her new friend Koshiba. She has a secret crush on her uncle.
