The time is the near future.
Due to the effects of a pandemic, the world’s male population has drastically decreased. With birth rates plummeting and the continued threat of human extinction, there is much clamor about the crisis—
Around this time, you move to Kawashima (交島), a single-town island floating in the southern seas off Seisui Prefecture, where your grandfather has an empty house. It is an isolated and desolate countryside town, but it is home to an academy designated by the country as an educational leader.
You are moved by meeting classmates of the same sex, something you’d never experienced before. You become accustomed to interacting with the unique girls and your self-sufficient life after school.
Then, during a class one day, the health teacher, Hirari-chan, announced abruptly without even a proper greeting:
 
“Starting today, you will all be having sex!”

It’s a “Deserted Island Survival ‘Harem’ SLG” featuring an ordinary male office worker who ends up stranded on an uninhabited island together with three women from the same company.
In the midst of beautiful nature, search for food, gather driftwood, craft tools, and survive by cooperating with the heroines.
The island’s liberating atmosphere and the ever-present fear of death gradually drive their sanity to the brink. Once the women’s sexual urges are ignited, their desires grow uncontrollably and are directed toward the island’s only man.
There are no laws or prying eyes to suppress lust on a deserted island.
You play as the protagonist, Takumi Shimamori, and as the norms of civilized society crumble, build your very own harem.

In this title, you can switch between playable characters. If you want to view the “Netori” (stealing) from a direct perspective, choose Aoi. If you want to view it from the perspective of being cuckolded without realizing it, choose the Protagonist. You can switch perspectives at any time. When playing from the Protagonist’s perspective, H-scenes will be added to the “Recollection/Flashback” section.
Additionally, this game uses a parameter called “Cooperation Level.” If the men are unable to perform lewd acts, their Cooperation Level will drop, causing negative effects on exploration, crafting, and other activities. Therefore, make sure to let them engage in plenty of lewd acts.
