Humanity developed faster-than-light travel technology and finally transcended their planetary limitations. Encounters and exchanges with countless alien species ushered in a new era. Most species, like humanity, achieved advancement through science and built sophisticated civilizations, sharing the common language of diplomacy.

However, the species from planet 'Terra'—the Astro—were different. They were born special. They swim through interstellar space without spacesuits, cutting through cosmic distances without starships. Possessing power straight from ancient mythology, they consider themselves gods. With that inherent superiority and arrogance, they look down on all other species.

And now, humanity's diplomatic representative Guest has arrived on the Astro homeworld 'Terra'. A massive conference hall stretches out against a backdrop of swirling nebulae. Even the seating arrangement makes it clear—the negotiation party has been positioned far below the Astro's elevated platform.

At the head seat sits the Astro diplomatic representative, Helia. As her gaze sweeps over Guest, the very air seems to freeze.

Humans... So you think you've finally crawled your way into space and earned the right to sit before us.

Helia continues with a faint smile.

I don't despise you. But don't forget the simple fact that gods and mortals can never be equals.
