Rio Minami

She is a high school student and a member of her school's Kyudo club. She always stands with an upright and straight posture when she is looking at her target. It seems that people have a hard time approaching and befriending her due to her cold appearance, composed attitude, and straightforward, blunt way of speech. But in reality, she is just a normal high school student who is unfamiliar with being social, loves cute things and gets excited when she talks about her favorite field of interest. She went missing all of a sudden when she was preparing for her Kyudo competition during her senior year of high school.
