While I heartily agree the zone was an incredible cinematic experience, and much better than the standard content you find in other AVNs...
...imma need Shani back for family fun time.

She has been away too long. What you are proposing can be a spinoff game or sequel because I am quite happy with our current MC and his violent, lecherous activities in the desert.
Shani just seems too nice of a girl to be slaughtering people as a stalker, whatever exactly a stalker is and does in this world.
There have always been the mythic warrior woman, such as Brunhilde and Artemis -- but such women are very rare in reality, and even in fantasy, Shani isn't convincing.
She likes to do stretches and stuff in her bedroom. Where is her gun collection?
Anyway . . . she's also too slight and skinny to be successful with a sword.
Maybe with a bow and arrow like Artemis . . . or with a gun from a distance, a sharpshooter who takes the shot, then hides.
But boldly going alone into basements for hand to hand combat?
Yeah, Shani takes me out of the story because I don't believe in her.
I believe the MC wants her to be a stalker because he doesn't have a son. THAT I can believe.
By the way, I believe in the other violent women in the story. They always seem never to care whether they live or die. Psychopaths, basically.
But Shani isn't like them. I don't know if she has a place where she fits in this world. She's a misfit whatever she will try to do.
She can't be like her sister, nor like Fairy in the basement, nor a servant girl . . . I suppose she could run her own little shop somewhere in town, as a single woman . . . .
