Synopsis
There is a fluffy existence on this star. I don't know if it's a living thing so far. But he stands here in the shape of a person. All fluffy people exist, imitating the appearance of the lost. I don't believe in the so-called "revival" ... In front of me, fluff swirled and a little girl appeared.

"Fluffy-san 773".

I continue to suffer from the noise of thought. That can't be mistaken. He was lost from my world ten years ago.
