I see you're point but if they are Li's I count it as Netorare. Like I said, I wish there was a better tag to get across "I don't want anyone but the MC getting action while I'm playing the game" but there isn't. If they are fucked by others before we steal them that's fine, I care about if they are fucked in the current time frame of the game. An Li is an Li, whether the MC initially likes them doesn't effect whether they are an Li, only whether they're an Li for the game itself matters.Well I would like to clarify something. (this isn't to argue but maybe it makes you understand better)
The story is about a corporation that, in the shadows, is capturing girls and turning them into sex dolls. (which are basically sex androids made of humans but mind controlled) Then they will be sold off as sex droids to people.
The current turned girls have scenes in the "years ago" part. Which is before MC is of age and not even introduced yet. He doesn't even know them besides maybe Vanessa who is the sister of his crush. MC has no clue even what is happening.
(since I know nothing of the future this is my best guess) Once the MC figures out this is happening, he will go after the corporation and either turn them back or take them for himself. He might also fail in this depending on your choices hence the bad end.
There are more girls that MC will not even know that will be turned. He only knows a few of them and hates half of them. This is why it is not netorare. Since girls aren't being stolen from him really, but he will steal them eventually if you go for the harem.
This makes it netori not netorare since you steal others girls.
The game isn't also purely about the MC having sex with girls. It rather is a story with sex in it. But the main focus is way more on the story then the sex.
Are they fucked by others before you steal them yes. And if this is not acceptable for you. Sure that is understandable for me. And not a game for you.
Let me give an example. I'm playing a game and the MC meets an Li in the story, if that Li is not a virgin or has fucked before I meet them, or have years ago sex as you called it. I'm fine with that. But if the Li get's fucked in the current time frame of the game while I'm playing and there's nothing I can do then I would put that under the umbrella of Netorare since there's nowhere else it really fits. And I can agree that it's netori but since we can't stop them form having sex with others in the current time frame of the game I will also put it under netorare because of that. What matter to it being "netorare" is if it's an Li and whether you can stop it that makes it avoidable.
It might have also been how I worded my question. Maybe instead of asking if netorare is avoidable I should have asked something like "Is sex not involving the MC avoidable" maybe that would have been a better question.
