Souma, Nadeshiko

相馬撫子

She serves as both a teacher and a school nurse at the same institution where Sakuya and Shinichirou studied. She is also the guardian of Sakuya, appointed by the Shimazu clan. She enjoys teasing Shinichiro and Sakuya, and occasionally engages in mischief with either of them.
She also likes Shinichiro; at one point, she asked him to marry her so that he would no longer need to look for a job.
