Мисудзу Сотомура

Хироси's younger sister, beautiful but willful. A strictly business-minded person. As soon as she steps into the cinema club, she establishes her own rules and proclaims herself the director's assistant. She criticizes any movie she watches, making insightful and accurate comments. She is one of the few female characters in the plot who does not have romantic feelings for Jumpeyi; she cannot stand his indecisiveness when it comes to the opposite sex. She reveres Tojo for his writing talent.
