An island where you can't leave without raping an NPC / NPC姦しないと出られない島

I was so tired that I overslept the train and ended up on a strange island. There, as a player of the game, I can fuck all the female NPCs I want! Some NPCs only speak the same dialogue, while others have personality and will.

You have two days to escape,
If I don't escape in two days, my phone, which has the Player app installed without my permission, will explode with me.
It looks like in order to escape, I have to bang all the female NPCs in various places.
Now that this has happened, I have no choice but to fuck them.
