Utaha Kasumigaoka is one of the main characters of the Saenai Heroine no Sodatekata series. She is an up-and-coming young novelist and a student in class 3C who has a secret identity as a writer. Utaha is a tall and beautiful slim-figured girl with mid-back length dark hair that she wears a white hairband and different eye colors in the anime and the light novel. In the light novel, Utaha's eye color was brown. In the anime, Utaha's eye color was changed to scarlet red. Utaha is a hardworking girl who easily finishes writing their game's plot in the span of a night. Her usual disinterested expression gives off the impression that she is an unapproachable person. When she is with the people in Tomoya Aki's circle, she reverts to her disdainful self who enjoys making sarcastic remarks. She seems to be calm and quiet, but she actually has a sharp tongue. Utaha can be a little aggressive, for example, when Tomoya said that he and Megumi would go out on a date. Utaha is also very intelligent and is the smartest student in the school. She even writes plays for the drama club as a hobby. She is also a little bit self-centered, but she never talks back to her parents, making her well-mannered. However, when Tomoya complimented her one time, she acted like a shy, embarrassed girl instead of her usual cold self and called Tomoya by his first name instead of Rinri-kun.
