Itou, Nobue

伊藤伸恵

Nobue is the oldest main character. She is Chika's older sister and typically holds the final say in all matters. She frequently attempts to "borrow" money from Chika to purchase cigarettes. Nobue is constantly looking for a part-time job to earn funds for more cigarettes, aiming to soothe her nicotine addiction.
The narrative implies that Nobue experiences a form of sensual pleasure from observing the girls perform cute actions. In this regard, Nobue seems to appreciate the moe aesthetic. The anime shows that Nobue favors Matsuri and Ana over Chika and Miu.
The character of Nobue differs between the manga and the anime. In the manga, she is a sixteen-year-old high school freshman, whereas in the anime, she is a twenty-year-old junior college student. Her age was likely altered because smoking and drinking become legal in Japan at age twenty. Although she introduces herself as sixteen in the first episode of the anime, this was meant as a joke, as she promptly clarifies that she is twenty.
She tends to behave somewhat less maturely in her manga version, engaging in actions such as tricking Matsuri into believing that Miu is dead. Her appearance changes significantly in the early stages of the manga, particularly her hair, which shifts from blond to dark brown (and is black in the anime).
