Kotori Matsunohara (松ノ原 小鳥)

The commander of the City Patrol who answers directly to the magistrate herself. His skills and abilities are a mystery until he uses them on one of the Mushigari's member, who is found killed by a sword blow, which also cut the stone behind him. He doesn't often go on the field with the patrol, but he must be very skilled to be its commander.
