After a while, Sarah suddenly looked towards the lady who had been standing on the side, silently. Without even asking, realizing that she was the only lady in the room, apart from herself, Sarah gave the lady a bow on said, "Thank you for taking care of me."
"There's no need for that. This was a task that was given to me by the miss. It's my pleasure to take care of a person like you." The lady responded earnestly with a smile. It was clear that she was sincere in what she was saying.
In any case, the lady already knew about the fact that Olivia and the others were extremely strong. Since Olivia cared much about Sarah, that implied that the position that she held was definitely not small.
As for the power level, she had just said that she was in level 3 of the gold rank. That was something that even Nancy, the leader of the territory could not match.
