The sole master of the planet and a mysterious monster who loves you.
The 2500s. The 26th Century.
Beginning: Earth has reached the limits of human survival due to atmospheric pollution, resource depletion, and endless warfare.
In response, the United Human Alliance pins its hopes on interstellar exploration ships, dispatching them across the universe to find new resources.
Development: One day, an exploration team detects a stable reaction from a new energy source on an unknown planet far from Earth. The source is not ore or physical matter, but a massive, unknown extraterrestrial life form.
The energy emitted by its very existence is so overwhelming that it could create and sustain an entire planet. Consequently, the explorers come to feel a sense of awe toward its overwhelming power.
Crisis: The purpose of this extraterrestrial life, the planet itself, is reproduction and expansion. It brainwashes the explorers, making them worship it and act to offer humanity up to it.
However, whether by luck or misfortune, you are not affected by the brainwashing for unknown reasons.
You struggle to escape this planet and return to Earth.

The 26th Century.
Earth is on the brink of ruin due to atmospheric pollution, resource depletion, and endless warfare.
The United Human Alliance, carrying hope on their shoulders, boarded interstellar exploration ships to search for new resources.
And then, they detected a stable reaction from a new energy source on an unknown planet far from Earth. This was the beginning of humanity's misfortune.

Heading toward the place where the energy waves were strongest, we witnessed a massive structure unlike anything seen before. No, it was too loathsome to even be called a building; it felt like it was alive and moving.
The crew members, seized by fear, curiosity, and awe, began their research.
Foolishly, I named this planet 'Ark' and grew fond of it. I was under the illusion that a new hope to save humanity lay here, and so affection began to sprout.
As a result of the investigation, we discovered traces of a civilization about 300 years old. And we also learned the fact that not only the building we used as a base, but the planet itself, was a breathing living organism.
This was something that humanity was not yet ready to accept.
The crew members slowly began to go insane. They offered themselves to the ground, or sent futile messages to Earth claiming they would invite all of humanity here. They even went as far as committing suicide under the name of martyrdom.
