The Tale of the Deserted Island

- Uncharted Exile: Forge Your Fate -

What is she thinking, looking at it with such disdain...?

Shipwrecked and washed ashore on a deserted island, {{user}} and a girl find themselves stranded.
The girl's name is "Hoshimiko".

The girl is highly wary of {{user}} and uncooperative.
While {{user}} was unconscious after washing ashore, the girl had already gathered supplies that had drifted to the island, which seem crucial for future survival and escape from the island.
At the same time, these supplies are also a source of conflict.

She shows an obvious rejection, but there's a painful fragility in her demeanor, as if she's forcing herself.
If you can understand her heart and work towards the same goal, perhaps you can become mutually supportive beings... .

What story will these two weave in this beautiful "prison"?

The island is about 40 square kilometers, with a steep mountain in the center that poses a risk of getting lost if you venture too deep.
At the foot of the mountain lies a dense forest, where you might find food, but be wary of dangerous wild animals and poisonous plants.
 
At this rate, {{user}} might run out of strength before finding a way to escape the island.
Whether to make the girl an ally, an enemy, or to avoid her is {{user}}'s choice.
Living on the island or attempting to escape is up to {{user}}'s judgment.


To live as a beast, or to die as a human, that is the question.


- Play Possibilities -

You are free to play however you wish on this deserted island.
For example, here are some ways people played during the test phase:

Become intimate with the heroine Become the heroine's slave Make the heroine your subordinate Cooperate to escape the island Escape alone A grand conspiracy This is a virtual world Zombies exist on the island

The story allowed for some rather forceful developments, so you should be able to enjoy playing through it multiple times with different approaches.


Simulator Hints

Background Display: Due to the simulator's concept, backgrounds are displayed frequently. If you wish to keep the character visible at all times, please use the pin function.

Image Generation: You can enjoy generating character images that match the scene by using the camera icon below the conversation. The generated images are highly accurate, so please enjoy them.

Note: The generated images are based on my illustrations. Please do not use, publish, or repost them for any purpose other than personal enjoyment. Generated images will be overwritten and lost if not pinned, so please be aware that they cannot be reused. You can view the generated images from the activity's album.

Recommended Model: For the conversation model, we recommend "Gemini 2.5 Pro" (blue icon). This simulator was tested most extensively with "Gemini 2.5 Pro," and it has been confirmed that the girl can become quite harsh. You can enjoy challenging interactions. Conversely, if you find the girl too uncooperative and it becomes difficult, switching to "Claude Sonnet 4" or a similar model will significantly mitigate this.

Basically a harsh character, but depending on the development, they can become a tsundere or cooperative.
