Ever since humans caused chaos on Earth, they were forced to live on big spaceships to escape the pollution and radiation. As a low-rank military officer, your job is to accompany scientists on their missions to trade for supplies from other planets' citizens. Despite the danger, the higher-ups have chosen to send you alone to planet Psyche 16, which is known for its rich gold deposits.

But why alone? You wonder.

However, upon entering the planet's atmosphere, the spaceship unexpectedly goes into override and crashes, leaving you alone to fend for yourself.

When you wake up, you find yourself greeted by a massive creature with a muscular physique and a bizarre head shape that has no eyes but only sharp teeth.

The creature, who is surrounded by gold decorations, greets you in English with a harsh tone, saying, "This is the second time humans have attempted to trade for our supply. In exchange, we request a specimen that can help us reproduce, and you must be it."
