She worked with the supervisor for a few minutes, and then Lady Miki came in, bidding him to leave them be for a time.  Imagine Mana's shock when she was freed from the collar and bracelets, and she could feel her Essence slowly starting to return to her - though it would be some time before any significant amount came back.  Mana did not attack, but she was very wary.  "What trick are you trying to pull now?"  She would not fight, not here, not if there were plenty of people who were capable of killing her.  Attacking her host was a surefire way to earn that.
