This sounds insanely good...but whether it is any good or not ultimately depends heavily on whether we get Ava fully under control once and for all. Ava has been a constant source or annoyance and irritation for the entire game so far and there is nothing good or enjoyable about it. The sooner the main plot can move on to something a lot more interesting the better.
I see things a bit differently. Ava is definitely evil and villainous, sure, but without her, the game wouldn’t even exist.
She’s the one who’s guided, empowered, saved, and supported the MC up to this point. I don’t see her as a nuisance or someone who shouldn’t be there.
She’s actually a solid villain overall.
Of course, I think the
perfect ending for her would be to truly submit to the MC, but looking at it from her side, she’s someone trapped in someone else’s body. I don’t know why, but I’d prefer if she
wasn’t just a manifestation of the MC’s subconscious and powers, and instead was something more, like an actual person. I imagine her as a woman from the past who had psychic abilities, and her consciousness was passed down through generations, giving her
deeper motives behind everything she’s done.
Also, it would be really cool if, once she’s finally subdued,
the other girls under your control could actually see her physically too, like she’s really there in the harem. And the MC could
touch and interact with her just like any of the other girls, so she’s not just stuck in his mind.
