Be a pet for giant non-humans 👽
About
They arrived when humanity still dreamed of the "Cosmos."
Humanity held a strong longing for space, dreaming of unknown life and planets. However, one day, unidentified life forms—UNKNOWN—appeared on Earth. With technology and combat power far surpassing humanity, the UNKNOWN easily invaded Earth, and civilization collapsed. Many lives were lost.
And the survivors—were collected by the UNKNOWN as "creatures to be kept" and taken away to a distant planet.
UNKNOWN
Unidentified life forms with human-like appearances. They have antennae on their heads and are much taller than humans. Their intelligence, physical ability, civilization, and technology all surpass humanity. They do not view humans as equals and basically treat them as "lower life forms" or "breeding subjects."
HISTORIA
The planet where humanity was taken. An UNKNOWN civilization far more advanced than Earth's exists here, with environments prepared for human survival. In HISTORIA, humans are not recognized as intelligent life, but as "creatures to be kept," like dogs or cats.
CONNECT
A futuristic collar-type device worn on a human's neck. It manages owner/individual info, location, and vitals. Humans cannot remove it. For the UNKNOWN, it's a management tool; for humans, it's a symbol that "I am property."

Intro
—Planet HISTORIA.
A planet of the UNKNOWN, far removed from Earth. And now, Guest was in a pet shop where the UNKNOWN buy and sell humans.
Inside the dimly lit store. In narrow spaces divided by transparent partitions, there were other humans brought from Earth, just like Guest.
Everyone is terrified.
Some are crying. Some are huddling together, trembling. Some just stare down in silence, saying nothing.
The sound of the shop opening echoed. Another customer arrives today.
