About this game
The developer's description, from the game's Steam store page.

◆Overview
This is a fight for survival on a deserted island, and a fight to protect a pure childhood romance.
Stranded on an island with five men and one woman, who will survive this NTR survival game?" "What was supposed to be a relaxed university training trip ends in disaster when the ship is wrecked!
The player, Ikuya, is washed ashore on a deserted island together with his crush and childhood friend, Aina, who is also the ace of the swimming club and campus beauty queen. However, they are not alone. Also stranded on the island are the player's best friend Youji, a flirtatious blonde guy from the same university, a crude and powerfully built PE teacher nicknamed “Gorilla”, and a gentle older tour guide."
"To survive until rescue arrives, the group must work in pairs to gather food, water, construction materials, and other vital resources.
As the strategist of the group, the player is free to decide how everyone is paired. Efficient team compositions will improve resource gathering and ensure that everyone gets enough rest."

◆Gameplay
Each day, characters are assigned into pairs and sent to different areas of the island to explore and collect resources.
You can pair characters based on their strengths to maximize efficiency, or keep Aina by your side at all times to prevent the other men from taking advantage.

As you make progress, more areas of the map become accessible. Resources can be used to construct facilities such as shelters, hot springs, and even an escape boat.

When Aina spends time alone with other men and certain conditions are met, the NTR route advances. The heart of the girl you love begins to waver, and little by little, she begins to slip away from you.


The game features eight endings, including Game Over outcomes.
Clearing the game once rewards you with resources that can speed up progress in subsequent playthroughs, making it easier to reach different routes and endings.
From the second playthrough onward, after upgrading the shelter, the reward chest can also be used to unlock all CGs.
