It's NTR and mindbreak. Tomo betrayed MC, Cotton Candy and that little demon got mindbreak. And some incest.

Relax, it's not exactly them. It's their counterparts. Those two series are separate stories. They are not really related.
It's somewhere on nhentai, I got the link from Kissmanga, some dude posted it. It's hard to find it on phone... Orz Sorry :/ I will post it but you have to wait.
Isn't Tomo the MC?? So she betrays herself, and do some incest?? How did she betray herself in the first place??
