The monkey scenes were the best part.
Who ever listens to the old ship captain who says "going way over thar, eh? bad juju on that island, you sure bout' this?" Not this chick, she's ready to go exploring! And an island where all the women have recently abandoned is the perfect place! Yeah, not the smartest tool in the shed.
Turns out the island is cursed and someone monkied with the shrines that offset the curse, meaning the men have gone into horny overdrive mode, and are willing to trick, influence, corrupt Natsuki into being their community fuck friend. Of course Natsuki isn't exactly cool with that idea, but, she can't do much about it as her quest to repair the shrines will corrupt her with each one.
The routine you'll find yourself doing is visiting all parts of the island in the day and at night, activating a shrine after uncovering the hints to their locations, and then re-exploring the entire island at day and night. This allows you to find all the secrets, talk to all the NPCs, earn all the sex scenes, and so on and so forth. However in my playthrough, I somehow managed to stay totally free from Natsuki becoming impregnated. And I also unwittingly saved an NPC that takes down the cursed god of the island, resulting in what is likely the cleanest run for Natsuki.
Sure she still sucked off most the island, let them take her ass to pound town, fooled around with the young and the old men, and watched a monkey face fuck the only other woman on the island, but somehow I must have done everything in a way that prevented Natsuki from falling to the dark side too much. Heck I was actively trying my best to turn the other chick into a money's wife, but no dice, so after I got my ending I unlocked all the scenes to find out I missed out on the best ending!
Yes Natsuki can become the baby factory of the village, she can also become the slut who lends her holes to the men as needed, but a third ending also has her and the other chick become the monkey's wives and fuck him and their monkey children until the island is nothing but horny monkeys.
So why did I like this ending the best, why did the monkey scenes strike home for me? I think it is because the monkey is seemingly innocent, and the girls don't see him as a threat like they do the other human males. So he gets away with more, subtly corrupting the girls, kinda like the other games that the developer of this one has made. Overt stuff just doesn't do it for me.
