Just from early vibes alone, doesn't seem like it's crazy good. In fact, I'd say she's pretty dtf right off the bat since she's got stereotypical tsundere looks and barely puts up a fuss when harassed. From the first masturbation scene alone, she's already imagining her defeat by the hands of her enemies. She's a closeted slut looking for an excuse to fuck and got a golden ticket to do just that by an unreasonable debt.
I mean, if you're into that, more power to you. But if not, there's probably not going to be a whole lot of what you're looking for. This descent into corruption feels like some kiddy pool depth to me.
