Yagi

A classmate in 1st year, class 2. She has slightly wavy long black hair and sharp eyes. She didn't like Kurokuma at first, but thanks to Sakamoto's scheming, they became closer and became friends. During the sports festival, she failed to receive the baton from Sakamoto, which caused the girls' resentment and made her feel down. However, thanks to Sera's self-sacrificing atonement, she avoided embarrassment and realized it was for her sake, leading her to appreciate Sera's cool side.
