Harunohara Yuuna

She is the same age as the protagonist and they used to be rivals in a card game they played together. After the protagonist saved her from a difficult situation, she began to look up to him as a hero. While she currently has an aversion to men due to that incident, she seeks advice and relies on the protagonist when they reunite. Although she is shy, she shows a cheerful side of herself and enjoys teasing the protagonist.
