Monogatari no Naka no Hito

A young noblewoman had once aspired to become a magic user, inspired by ancient stories, but her enthusiasm waned during her time at magic school. While in the forest, she is saved by a mysterious man who uses magic reminiscent of those old tales. Though clearly experienced, he shows great excitement about learning new methods. As formal training is only available at magic schools, he changes his appearance to look younger and joins her on the journey back to school.
