Andou, Chiharu

安藤ちはる

Mayuta's (Andou-san) younger sister, she holds great admiration for her brother, whom she calls "Mayu-nii". She seeks the woman she believes is stronger than Mayuta and caused him to quit his delinquent gang; she also enjoys playing "kancho" on her opponents, a game typically played by school children in Japan that involves poking someone's bottom.
