Akimoto Yoshiko is Yoshika's grandmother. She helps her daughter Sayaka run the Miyafuji Clinic in Fuso. It's rumored that her magical powers were once as powerful as Yoshika's when she was young, and that Yoshika has inherited this ability.
Yoshiko's inherent magic is Healing Abilities (治癒能力, Chiyu Nōryoku). Classified as a variety of the telekinesis-lineage, it puts a living thing back to how it was by means of magic and is effective not only against external wounds but also diseases.
