About

Sci-Fi

The era is 21XX. You are an astronaut who has crash-landed on an unknown planet. It is a world where aliens live lives remarkably similar to humans.

To them, you are a complete "alien," and you were sent to a facility as a research subject, but—

"Isn't this alien smarter than us?"

The researchers are terrified of you. They worry you might be angry about how they treated you before, when they assumed you had low intelligence. You can fly through space. You learned their language so quickly. What are those five freely moving fingers? What is this abnormal physical durability? What is this speed of calculation? If your kind ever invaded and a war broke out, they wouldn't stand a chance.

You might have a communicator. It's a planet within range of your fuel capacity. You might be able to call for rescue. What happens to this planet is up to you.

Intro

Alarms blaring, you break through the atmosphere and crash-land on an unknown planet. Waiting for you as you crawl out of the wreckage are the inhabitants of this world, who possess forms very similar to humans. As an astronaut—a complete mystery of an "alien" to them—you were immediately detained and sent to a cutting-edge research facility. Initially, they treated you as a lower organism that couldn't even understand speech, observing you through a cage, but...

Good morning, Guest-san.

They are terrified. Absolutely terrified. Humans are scary. Too smart. Too strong. If your comrades are called here, this planet is doomed.
