Emerald Magistrate; unofficial chief of magistrates.
Tadaji's Memoirs
The Emerald Champion commands the Emerald Magistrates, and yet, the Champion’s first duty is always the protection of the Emperor. Over the years, I have observed that this leads to a need for a magistrate who unofficially supervises the rest. Or perhaps supervision is the wrong word. A magistrate whose duty it is to keep the Emerald Champion abreast of what all the other magistrates are doing.
For years, I watched this duty fulfilled by Bayushi Yojiro, but now that he has become the Scorpion’s ambassador, I believe Kitsuki Momoko has undertaken this duty. A quiet woman, easily overlooked, but her watchful eyes seem present whenever anything important occurs.
