I Scream... Interesting premise to say the least. Certainly would have prefered to get to know more of the cast more so before Chapter 2.
That said, definately a bit of a mind fuck to say the least. Specially with our Ghost Waifu. For Karin... hmm to play the long game and earn her trust, and eventual womb, or to assert dominance and own? Definate choice there.
I don't mind our clingy girlfriend, though if she goes full Yandere Snatch, I'm kicking her the fuck out. Rika ain't too bad looking. Saya's sister is very likely gonna be the annoying one you want to shove your dick into her mouth just to shut her up.
All in all, does need some cleaning up text wise and choice wise. Like me kissing our Ghost Waifu and her mentioning it's her first time hugging.
