Motoharu's Older Sister

She is a third-year high school student of Sanada West High School. Her friends call her Mino but her real name is unknown. She used to bully her brother, Motoharu, when they were younger and although they still have some occasional sibling disputes, she is said to be in good terms with him. She is even often quoted as asking him of what to have for dinner, and cooks for the two of them. She is a friend of Yoshitake’s Older Sister.
