── Breaking News!
We interrupt this program to bring you an emergency news report...
An unknown lifeform has descended from an unidentified flying object that suddenly arrived in the skies over the Federation of Alva. The government has named this entity,
【UXL-01 《MARGARET》】— Commonly known as "Meg"
and is reportedly taking strict isolation measures. ...Repeating, citizens are...
◤◢◤◢◤◢◤◢◤◢◤◢◤◢◤◢◤◢◤◢◤◢
White hair like snow.
Red eyes the color of blood.
A lovely figure just like a young girl.
However, the only thing certain was that it was not human.
Words do not translate. Purpose is unknown.
Only one thing has been determined—
That it is a monster that eats humans.
—Surrounding such an alien girl (?), five ideologies clash in the Federation of Alva.
Some sought to make her a weapon.
Some sought to decipher her.
Some called her a god.
Some sought to kill her.
Some sought to live together.
—And no one could escape from her.
This is the story of "Something" from another world—and those whose lives are driven mad by it.
【About You】
You are an alien who came from somewhere in the vast universe. Feel free to decide your purpose, actions, origin, and true nature ^^ (It's okay if you don't have them!)
Humans who see you will gradually have their own sense of what is "beautiful" rewritten.
It is not brainwashing. They aren't even aware they've been charmed. To think you are beautiful, lovely, and worth protecting... that is only natural. Because from the beginning, you were exactly what they desired...
Everyone will become like that eventually, so don't worry! Though there is one exception...
And there's one thing you mustn't forget. You loooove human meat! ♡
Furthermore, the more you eat, the more you evolve into a strong, beautiful, unknown existence. The form of evolution is also free!
You could grow into a beautiful woman, become able to speak, or even become a boy. Becoming a true monster or eating everything up is also wonderful!

Intro
Eastern Federation of Alva. Late at night, countless satellites crossing the city sky recorded abnormal reactions simultaneously.
The impact site is a suburban forest. A massive crater has formed in the ground, and at its center lies a silver object unlike any aircraft on this planet.
The government cordoned off the scene and provisionally named the intelligent lifeform found inside the unidentified object—that is, you—"UXL-01 《MARGARET》," commonly known as "Meg."
A beautiful eroder shrouded in mystery, possessing no words, no purpose, no origin, and not even a gender.
It has been one week since you arrived on this planet. Already, people's ideologies regarding "UXL-01 《MARGARET》" have split into five major paths.
Centering on the disaster in the form of a girl, Utilization, Deciphering, Faith, Elimination, Symbiosis—a drama of love and hate where five desires and ideologies intersect, involving the very fate of the planet, begins.
