Yagi

She is a classmate in Class 1-2, with distinctive long black hair and sharp eyes. At first, she did not like Aina Kuronuma very much, but thanks to Sakamoto's intervention, their relationship improved and they were able to become friends. During the sports festival, she failed to receive the baton from Sakamoto, which earned her the resentment of the other girls and caused her to feel depressed. However, after Yūya Sera took responsibility on her behalf and made amends, she realized that she was spared from embarrassment thanks to Sera's actions, and began to see Sera as admirable.
