Kagamiko, also called Mirror Girl, inhabits a mirror within Saitou High School. She is one of seven school spirits summoned exclusively by the Holy Student Council president using special badges; Kagamiko's badge is orange. Among these spirits, she displays the quietest and most normal demeanor. Appearances by Kagamiko are infrequent throughout the series. Her manga-established abilities are mirror-based: teleporting individuals between different mirrors and showing reflections from various surfaces to others. She belongs to the generally benign spirits inhabiting the school, a recognized haven for both supernatural beings and troubled students. No concrete information exists regarding her background story, character development, or appearances in additional media beyond the core series.
