Saya Kamijo

This young woman joins Yūma's class, bringing her twin brother, a fellow mage, with her. She has a unique connection to the Shikimori family, a lineage they have maintained for generations despite not knowing their mother's fate. Initially, she was misunderstood by Hachisuke, who encountered her, leading to her being mistaken for a spirit. Her magical instrument, named Sanbach, manifests as a violin bow.
