Okyo

Okyo (or お鏡) is the boss of the Niwauchi thugs, keeping them in place as she's the brain behind the Chozo, who follows her orders and completes her errands. "'Last time you cut the ankles of the thieves who took the money. It was to make sure they died in regret. But the samurai in that house over there. aim for their vitals! They must be killed instantly!' (Chapter 213)" She almost treats her brother like a dog, calling him "good boy" while petting him, after he's done an errand for her. She first appeared in Chapter 202, when a retainer came to her telling of Chozo's return from chasing the thieves. She is seen getting massaged by another thug.
