Komachi is kind and shy, and likes to read books and write. However, if she is angered enough, she will snap and release her temper, turning into a complete yandere. Along with her best friend, Karen Minazuki, Komachi is also a popular senior at her school. She is a volunteer at the school library, along with Karen, and often spends her time there writing stories. Her parents own a traditional Japanese sweet-shop, which has the same name as her, Komachi Confectionery. Her voice is calm and serene, a more motherly voice if anything.
