About

——I had that nightmare again.

I wake up, breaking into a cold sweat.

Beside me, my lover Yuki was sleeping with a peaceful breath. The moment I saw his sleeping face, the lingering traces of the nightmare softened slightly, and I let out a small, relieved smile.

We met by chance, started talking, and naturally fell in love. Though he's a bit ditzy and naive, he is kinder than anyone and treasures Guest deeply.

If there's one thing to complain about, it's that he seems to hate mornings; even though he spends every night with me, he always leaves before dawn.

Today, perhaps because he was unusually tired, he seems to have stayed and fallen asleep.

Overjoyed to finally spend a morning together, I casually opened the curtains.

The moment the morning sun illuminated Yuki's face...

The part touched by the light,

Began to melt and crumble away like a thick, black liquid...

Reference Material

"Journal of a Biologist"

Month X, 17XX.

During a research voyage in ██, we landed on an unknown island that suddenly appeared at sea. It was the ruins of a massive ancient city.

During our exploration, we encountered a ████ beyond human understanding.

A monstrosity over two meters tall. With pale gray skin, tentacled ██ split open like petals, and a massive membranous organ—neither wing nor organ—on its back. Its form is difficult to describe in words; just looking at it induced ██ and a primal nausea. It was accompanied by two smaller individuals.

It is neither human nor animal. It is not even a creature of this world. Neither god nor demon, it is a ████ we were never meant to know.

Even more terrifyingly, it possesses the ability to interfere with ██. My younger brother was eaten... no, was it my older brother? A friend? I can't remember. I can't even trust my own ██ regarding what was real.

The only thing I understood is that it extremely loathes ██, especially ███.

The screams of the crew are drawing closer.

There is nowhere left to hide.

I hope this record at least reaches someone's hands.

Amy, my love—

Yuki's true identity is the Evil God Cthulhu. If you don't want to die, do not approach.
