The necklace as some of us knows, restrains her powers to not be detected, that was the reason why her mother did whad she did ofc just to protect her. And she never was a slave to begin with. I am very curious of the extent of her powers honestly, she is very smart and inteligent on top of that she is pure, innocent, gentle, kind,curious & brave &cuuuutee!, and she learns things very fast from i noticed too, and i am very curious how she can be without it, and am waiting patiently for wayyyy more content and amazing story that comes next i also am very curious what happens next, Amazing work thank you NCrow once more.
Yeah, but the male goon slaves who attacked the priestess also had the same necklace, and as far as I'm concerned they had no powers they had to subdue with it, so it's probably just there to coerce them into submission. It is probably some mimd control aparatus that messes with the head of it's subjects to some degree, while also apparently inhibiting their powers. A side effect of that may be the fact that Ryoko keeps calling Ryo her master. My likelier theory, as a veteran who has played this game from around the first if not first version, is however that the story was originally that Ryoko was supposed to be a runaway slave (there are plenty of indicators that will likely be reworked when Ncrow gets around to do it) and she has ptsd, which has now been retconned to the story we know today. The master thing may stick around if Ncrow is into it, I suppose, personally I don't mind, but I get that some people may do.
Well it may be like that with those that attacked the priestess since the master orders them, so they had to obey the will who controls them, as with Ryoko is different case as above said, the person did nothing like that that may initiate her obey the will of the person who wears it for her, and yes i not mention what the necklace do too that is revealed ofc later by Natsuki (about her body being more mature shhh.).
