Nobue Itou

Nobue Itou is the eldest main character and Chika's older sister, often holding the final authority in their matters. She frequently tries to "borrow" money from Chika to buy cigarettes and is perpetually looking for part-time work to support her nicotine addiction. Nobue also seems to derive pleasure from watching the girls engage in cute activities, showing a preference for Matsuri and Ana over Chika and Miu.
