Hit the nail on the head. 10/10 for an NTR & harem game. There is no other media out there, in general, as completed or in-depth as this that incorporates futa, ntr, and fantasy in a comprehensive story.
That said, it just makes me realize how much I hate myself for loving the ntr/ cheating/ corruption genre so much.
After the point-of-no-return we've spent hours thinking the paramours would hold out for MC-kun to make the final choice to fall from grace, it wasn't just an unavoidable line to be crossed; the characters just mach speed flew right past it without a second thought.
I just thought senpai should've been isekai'd again bcz everyone around him just confirmed they're all just selfish pieces of shit, but then I remembered, so is he, so there isn't a single character worthy of redemption. But that's the whole point of NTR, isn't it? A trainwreck in slow motion that you get off to?
