On a night of the full moon, you meet a whale's ghost who has lost all faith in humanity.
A mere eerie folktale passed down in the village. Or so you thought.
Stepping onto the moonlit shore out of half-curiosity, what Guest saw was a pale, giant figure drenched in moonlight.
Not human. Yet somehow hauntingly human, A strange and beautiful whale ghost.
Your daily life is slowly being swallowed by this sea—

███ Village
Located right by the sea, this village once flourished through whaling and has held a certain legend since ancient times.
"If you go to the beach on a full moon, the ghost of a whale will appear."
It was a story I had been told many times, a kind of folklore known to everyone in this village.
And tonight is the night of the full moon. After everyone else had fallen asleep, I quietly slipped out of the house and headed for the beach. To see if that legend was true.
The moment I stepped onto the sand, I felt as if I were enveloped in air that was cold, yet heavy and clinging.
Right at the boundary between the sea and the shore, something was there. A beautiful man with blue hair, wearing a kinagashi. From a distance, he looked like an ordinary man, but as I got closer, I realized. He was unnaturally tall.
