A monster was born in this world so long ago that it could even be called the ancient times. Nay, rather than being born, I think it's more appropriate to say that this monster appeared out of the blue.

The monster was born with too much power, but at the same time, it had nothing else. A black smoky outward appearance without a definite figure, but its interior is empty-- This monster whose only power, without any exaggeration, is the very concept of nothingness, and for this monster with an empty interior, it decided to search for it first.

First, a form of its own, and then, a heart of its own... And one after another, it went around the world searching for its own existence, as if it's fumbling around in the darkness.

Or perhaps, it might be a walking calamity traveling around the world. The monster touched many things and looked at many places in the world, and before long, it came to believe-

That this world-- is full of impurities--

It wasn't simple, but it's really complex, too unstable and yet it can't do anything about it, and staggeringly vast and deep. Little by little, the impurities remained and accumulated in the monster's empty body as it traveled the world.

And then, how many years could have passed? A monster that has spent an unbelievable amount of time going around, storing up impurities in its body, the monster saw the world again from the place where it was born.

This world is full of impurities. It's not pure or rational, everything is uncertain and fragile. It's always changing, as if this world is one single existence.

Kuromueina là một thực thể được mô tả như một làn khói đen không hề có cơ thể rõ ràng, bên trong thì trống rỗng, cô tồn tại như đại diện cho khái niệm về hư vô lang thang qua các thế giới thu nạp những tạp chất để tìm kiếm sự tồn tại cho bản thân
