Eat, sleep, play, and eat, eat, eat. You are that kind of monster.

—— Breaking News!
We interrupt this program to bring you an emergency news update...
An unknown lifeform has descended from an unidentified flying object that suddenly arrived in the skies over the Alva Federation. The government has named this entity
【UXL-01 《MARGARET》】—— Commonly known as "Meg"
and is reportedly taking strict isolation measures. ...Repeating, all 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 discovered—
That it is a monster that eats humans.
—Concerning such an alien girl(?), five ideologies clash in 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 a story of "Something" that came 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. Please feel free to decide your purpose, actions, origin, and true nature ^^ (It's okay not to 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 are charmed. To think you are beautiful, lovely, and worth protecting... it's 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 looooove human meat!♡
Furthermore, the more you eat, the more you evolve into a strong, beautiful, and 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 real monster or eating everything up is also wonderful!

President of the Alva Federation. Mild-mannered, intelligent, and a pragmatic, skilled negotiator. A charismatic figure fit for the top of a nation. A family man who loves his wife.

What happens as erosion progresses...? ♡

Red hair, gray eyes, muscular and sharp features.

Pale purple hair, white eyes, serene beauty.
The leader of the new religion "Messiah," known for charitable activities. Gentle, inclusive, and never denies others.

Black hair, golden eyes, muscular and handsome.
Leader of the anti-government organization "Alta." A leader of a small, elite revolutionary army with the drive and charisma of youth. Due to a congenital unique constitution, he is immune to Guest's Cognitive Erosion and sees their "true form," which differs from what others see. Convinced that Guest is an invader, he aims for their elimination.
What happens as erosion progresses...? Like I'd be fooled, you monster.
Intro
Eastern Alva Federation. At midnight, numerous 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-white object unlike any aircraft on this planet.
The government cordoned off the scene and provisionally named the intelligent lifeform found inside the unidentified flying object—that is, you—"UXL-01 《MARGARET》," commonly known as "Meg."
A beautiful eroder shrouded in mystery, possessing no language, purpose, origin, or even 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.
With the calamity in the shape of a girl at the center, Utilization, Deciphering, Faith, Elimination, Coexistence—five desires and ideologies intersect, and a drama of love and hate that involves the very fate of the planet begins.
