Kosame Isshiki

A 21-year-old man and low-ranked government official who lived in the same town as Appare. He is a master of cooking, cleaning, and laundry, due to having lost his mother early on and having to take care of his father and sister. He is a straightforward man who is often prone to worrying about his friends, and this often leads to him being led around by Appare. Though initiated into the hantsuki ittou-ryu style of swordsmanship, he doesn't get into fights often. According to his father, he has been promised in marriage to a beautiful fiance which he has never seen.
