Ayase Nazuna♀

Nazuna is a childhood friend of Hideaki and at the beginning of the story transfers schools and comes to attend the same school as him. Her appearance, since she grew up in the city, gives her a contrast to those who grew up in the rural area where the story takes place, but she is very sociable and cheerful. After meeting Hideaki's circle of friends for the first time, she easily is able to blend in with them and gets along smoothly. She has excellent reflexes and always gets above-average grades in school.
