Cthulhu no Choushi ~Musei Doukoku~

Synopsis

A floppy disk arrived at the door of detective Horiguchi, who earns his daily bread by investigating affairs and searching for pets.

There was no sender's name on the envelope, only a notepaper that said, "I want you to find the person who wrote the nine notes on the disk," along with a cash deposit at a sum that hardly seemed like a prank.

Although he thought it was a strange request, he was hungry for work, so he reluctantly started investigating...

A businessman whose spirit has been taken over by a monster. An observer swallowed by the darkness of Antarctica. An amnesiac man discovered after an encounter with a strange insect...

In a storage medium that could no longer be called outdated, the world's most bizarre events were recorded.

How can one find the person who wrote such a delusional account? It seems that this is going to be a more difficult request than anticipated...
