Asakura Yotsuba♀

She started attending high school in spring. Is one year younger than the protagonist, Shinichi, who is also her childhood friend. She's a pure, honest and kind girl, which is a rare find these days. Back at kindergarten, she was often bullied, and after Shinichi saved her, she fell in love with him wholeheartedly. However, she was afraid of destroying their current relationship if she confesses, so she still can't convey her feelings. Still, because she can't properly hide her affection towards Shinichi, the two look like lovers when they are together, to the point that only Shinichi has yet to notice her love for him.
