Katagiri Miwa is one of the 3rd year students of Hidaka Koharu of the year 2007 and one of the Main Characters of High Score Dash. She is a young girl with messy, long blond hair. Miwa always comes to class smelling faintly of cigarettes, which Hidaka-sensei gives her a hard time over, usally she is seen wearing their high schools uniform what a ribbon around her neck but usually has a unzipped hoodie over it. She is usually called the "image of a trouble maker" from the things she does but she does look like a nice girl at first glance.
