A world full of lush green, beautiful towering landscapes, tall buildings in perfect shapes varying in sizes, the people are beautiful, no flaws and their movement synchronized sometimes.
Ugly and dark are not prohibited and not accepted in this world, if one is born ugly or imperfect he/she will be cast out, which equals to sending people into space without any bodily protection, everything he/she has will be confiscated that contradict of his/her possession.
But if one is not born ugly, it will follow the others and fill in the gap, if one cannot create or imagine something beautiful, they will be eaten or added to others collection and displayed in others room.
So no one shall do things that does not look beautiful or it will equal death, if one tries to oppose and change this law, all things that are beautiful in a sense, will shed themselves and show their otherside, their ugly side will show immense strenght and vitality, they will evolve and adapt instantly sending information through brainwaves.
If one adapts and evolves, the others will transform to obtain the one who leapt on a higher level, thus dealing with opposers, invaders are killed without any huge casualties.
So any disruption towards their world, their masterpiece, the opposers will disappear from this world.
But to record, there are only a few instances born ugly and showing flaws in this world, they are the children of the ugly not from this world, birthed by the imperfection outsider and a native.
Although the outsiders aren't welcome, if they show no imperfection, they are very welcome to this world, will be treated with luxury, but if the outsider is found to love carnal acts, evil deeds, bad posture, not respectful, they will be kicked outside the planet or worse, eaten alive.
To the outsiders this world is considered paradise, its just with restriction to not show any bad habits and develop bad thoughts, anyway the world is beautiful, everything in this world is beautiful, just like what its creator intended to cast away the mentally unstable.
So changes in the laws, questioning the perfect as imperfect, talking about immortality is a curse, imposing something not normal will be killed, just like a man acting like a girl and a girl acting her opposite will be killed, but if its fashion, death will show itself in the face of an illusion that looks so real.
So what if a group of transmigrators stumbled upon this world? Will they be shown of good and right side and dispise their perfection for them not being perfect? Or will they enjoy this world like a vacation and transform into a resident of this world.
