In the view of the fact Keymaster is mutiple protag, I would say that its MC who had NTRed Lucy by sleeping with other women since she is kinda trying to keep him for herself but in an extremely unlikable way. This is compounded by the fact she is so free and loose with her own sexual rights while creating a lie to deprive MC of his.
From someone who had tried 0.1 and 0.2 and in my own pov:-
I do like the magic world like feel.
I am fine with equal sexual rights and mutiple people doing the deed with one another, all the time even. Its an open society, i think its fine since that is the story's premise.
Furries, Futas, oh my I love me some fantasy races and situations too.
Dislike/Issue with the story:-
Lucy - in 0.1, she just straight up wants to fuck everyone but MC. She has romantics thoughs and feelings for him but just strings him along. In 0.2, dev tried to create a rationale for this behaviour but guess what, now dev added a jealous Lucy mindset where she wants to bang even MC's sister but she also chooses to cock-block MC.
Pseudo Sexual Equal Rights - MC was literally available/standing right there in a few of the scenes. As someone newly brought into a world of magic, its strange that everyone chooses to show their open society to one another except to MC. Also again, MC being new to everything reacts as nothing more than an observer. Lucy might be right about the defective cock!
I do not hate/am not against this Vn. I would like for it to succeed. But I would like to see it story rich like what dev had intented. But so far, it seems more to just fulfil various fetishes...
