A Russian quest. It started as a random thread where OP asked what monstergirl would people like to meet if they appeared on an island almost naked.
Then came another guy and started a wrtiting an interaxctive story that basically became what you see in the "got".
There's even a translation of it to English now.
>tfw been binge reading it for a few months now
This shit can get exiting as fuck, but god damn there's a lot of it. I'm only halfway through.
I think it's related to the thread when the first episode aired
