Before Naritoki, the magistrate was a woman named Matsu Shigeko, who resigned her office due to a self-perceived inability to effectively police the City of Stories.
Shigeko-san was first and foremost a warrior - a samurai whose code of behavior was particularly strict. Naritoki had nothing but respect for her, but (on occasion) expressed an opinion that she had been unable to adapt to Ryoko Owari because she lacked "flexibility". When regarding her entries, keep in mind that she saw all things in highly charged terms - either good and virtuous or evil and corrupt. There is little room for ambiguity in Shigeko's view of the city.As far as Gate knows, she was reassigned to a post in the Crab Provinces that would be more suited to her abilities. Clear Water Village would be the most likely location to find out further information.
